Pain In Fish: Weighing The Evidence, James D. Rose Jan 2016

Pain In Fish: Weighing The Evidence, James D. Rose

Animal Sentience

The target article by Key (2016) examines whether fish have brain structures capable of mediating pain perception and consciousness, functions known to depend on the neocortex in humans. He concludes, as others have concluded (Rose 2002, 2007; Rose et al. 2014), that such functions are impossible for fish brains. This conclusion has been met with hypothetical assertions by others to the effect that functions of pain and consciousness may well be possible through unknown alternate neural processes. Key's argument would be bolstered by consideration of other neurological as well as behavioral evidence, which shows that sharks and ray are fishes …

Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach Jan 2016

Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach

Animal Sentience

Key (2016) affirms that we do not know how the fish brain processes pain but denies — because fish lack a human-like cortex — that fish can feel pain. He affirms that birds, like fish, have a singly-laminated cortex and that the structure of the bird brain is quite different from that of the human brain, yet he does not deny that birds can feel pain. In this commentary we describe how Key cites studies that substantiate mammalian pain but discounts the same kind of data as evidence of fish pain. We suggest that Key's interpretations are illogical, do not …

Why Is Fish “Feeling” Pain Controversial?, E. Don Stevens Jan 2016

Why Is Fish “Feeling” Pain Controversial?, E. Don Stevens

Animal Sentience

In his excellent target article, Key (2016) develops a mechanistic argument in an attempt to show why it is unlikely that fish can “feel” pain or for that matter, “feel” anything. The topic is controversial and likely to achieve the goal of getting many hits for the inaugural issue of the new journal, Animal Sentience. In my view, the question is unlikely to be answered, for two reasons. First, because the proponents of the “fish feel pain” controversy are untrained and unskilled in the details and jargon of neurophysiology and/or neuroanatomy, and the opponents of the controversy, like Key, …

The Behavioral, Biochemical And Genetic Effects Of Sleep Deprivation In Zebrafish (Danio Rerio), Jade Catherine Boykin Jan 2016

The Behavioral, Biochemical And Genetic Effects Of Sleep Deprivation In Zebrafish (Danio Rerio), Jade Catherine Boykin

College of Graduate Studies: Theses & Dissertations

Vertebrate sleep is a universal phenomenon and encompasses an array of conserved behavioral and physiological characteristics. Studies of sleep in humans have shown that sleep deprivation leads to adverse effects to human health and additional stress. Teleosts have emerged as a useful model species to study the vertebrate stress response, given its stress axis has high levels of homology with the mammals, including humans. For this study, the behavior of zebrafish (Danio rerio) subjected to acute (24 hours) and chronic (20 days) extended light exposure was monitored and whole-body cortisol was analyzed as an indication of activation of …

Wildebeest-Associated Malignant Catarrhal Fever: Perspectives For Integrated Control Of A Lymphoproliferative Disease Of Cattle In Sub-Saharan Africa, Lillian Wambua, Peninah Nduku Wambua, Allan Maurice Ramogo, Domnic Mijele, Moses Yongo Otiende Jan 2016

Wildebeest-Associated Malignant Catarrhal Fever: Perspectives For Integrated Control Of A Lymphoproliferative Disease Of Cattle In Sub-Saharan Africa, Lillian Wambua, Peninah Nduku Wambua, Allan Maurice Ramogo, Domnic Mijele, Moses Yongo Otiende

All Peer-Reviewed Publications

Wildebeest-associated malignant catarrhal fever (WA-MCF), an acute lymphoproliferative disease of cattle caused by alcelaphine herpesvirus 1 (AlHV-1), remains a significant constraint to cattle production in nomadic pastoralist systems in eastern and southern Africa. The transmission of WA-MCF is dependent on the presence of the wildlife reservoir, i.e. wildebeest, belonging to the species Connochaetes taurinus and Connochaetes gnou; hence, the distribution of WA-MCF is largely restricted to Kenya, Tanzania and the Republic of South Africa, where wildebeest are present. WA-MCF is analogous to sheep-associated MCF (SA-MCF) in many aspects, with the latter having sheep as its reservoir host and a more …

Integrated Methods For Controlling Gastrointestinal Nematode Infections In Ewes And Lambs, Sarah Tammy Nicole Keeton Jan 2016

Integrated Methods For Controlling Gastrointestinal Nematode Infections In Ewes And Lambs, Sarah Tammy Nicole Keeton

LSU Doctoral Dissertations

Gastrointestinal nematode (GIN) parasites cause extensive damage to small ruminants, and Haemonchus contortus is a major concern to production worldwide. With the development of GIN resistance to anthelmintics, alternative strategies for control are needed. The major component of this study compared two strategies for effect on animal health and changes in GIN population. One flock of ewes and lambs (Strategy 1, S1) employed targeted selective treatment (TST) with an anthelmintic based on FAMACHA score, and one flock (Strategy 2, S2) employed sericea lespedeza (SL) supplement feeding and TST with copper oxide wire particles (COWP) based on FAMACHA score. S1 ewes/lambs …

Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown Jan 2016

Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown

Animal Sentience

Arguments against the fact that fish feel pain repeatedly appear even in the face of growing evidence that they do. The standards used to judge pain perception keep moving as the hurdles are repeatedly cleared by novel research findings. There is undoubtedly a vested commercial interest in proving that fish do not feel pain, so the topic has a half-life well past its due date. Key (2016) reiterates previous perspectives on this topic characterised by a black-or-white view that is based on the proposed role of the human cortex in pain perception. I argue that this is incongruent with our …

Could Fish Feel Pain? A Wider Perspective, Yew-Kwang Ng Jan 2016

Could Fish Feel Pain? A Wider Perspective, Yew-Kwang Ng

Animal Sentience

Key’s (2016) target article provides some strong arguments but also makes some logical mistakes. The arguments are not sufficient to support a definite conclusion that fish cannot feel pain. A multi-faceted perspective taking into account brain structure, chemical secretion in brain, animal behavior, and evolutionary biology may be useful and appears, at least in some aspects, to suggest the opposite conclusion from that of the target article.

Should Fish Feel Pain? A Plant Perspective, František Baluška Jan 2016

Should Fish Feel Pain? A Plant Perspective, František Baluška

Animal Sentience

Key (2016) claims fish that fish do not feel pain because they lack the necessary neuronal architecture: their responses to noxious stimuli, according to Key, are executed automatically without any feelings. However, as pointed out by many of his commentators, this conclusion is not convincing. Plants might provide some clues. Plants are not usually thought to be very active behaviorally, but the evidence suggests otherwise. Moreover, in stressful situations, plants produce numerous chemicals that have painkilling and anesthetic properties. Finally, plants, when treated with anesthetics, cannot execute active behaviors such as touch-induced leaf movements or rapid trap closures after localizing …

Fish Pain: An Inconvenient Truth, Culum Brown Jan 2016

Fish Pain: An Inconvenient Truth, Culum Brown

Animal Sentience

Whether fish feel pain is a hot political topic. The consequences of our denial are huge given the billions of fish that are slaughtered annually for human consumption. The economic costs of changing our commercial fishery harvest practices are also likely to be great. Key outlines a structure-function analogy of pain in humans, tries to force that template on the rest of the vertebrate kingdom, and fails. His target article has so far elicited 34 commentaries from scientific experts from a broad range of disciplines; only three of these support his position. The broad consensus from the scientific community is …

Fish Pain: A Painful Topic, Carl Safina Jan 2016

Fish Pain: A Painful Topic, Carl Safina

Animal Sentience

If fish cannot feel pain, why do stingrays have purely defensive tail spines that deliver venom? Stingrays’ ancestral predators are fish. And why do many fishes possess defensive fin spines, some also with venom that produces pain in humans? These things did not evolve just in case sentient humans would evolve millions of years later and then invent scuba. If fish react purely unconsciously to “noxious” stimuli, why aren’t sharp jabbing spines enough? Why also stinging venom?

Pain-Capable Neural Substrates May Be Widely Available In The Animal Kingdom, Edgar T. Walters Jan 2016

Pain-Capable Neural Substrates May Be Widely Available In The Animal Kingdom, Edgar T. Walters

Animal Sentience

Neural and behavioral evidence from diverse species indicates that some forms of pain may be generated by coordinated activity in networks far smaller than the cortical pain matrix in mammals. Studies on responses to injury in squid suggest that simplification of the circuitry necessary for conscious pain might be achieved by restricting awareness to very limited information about a noxious event, possibly only to the fact that injury has occurred, ignoring information that is much less important for survival, such as the location of the injury. Some of the neural properties proposed to be critical for conscious pain in mammals …

Postnatal Expression Profiles Of Phospholipid Hydroperoxide Glutathioneperoxidase In Spermatogenesis In Mice, Ki Youn Jung, Chunmei Lin, Jung-Min Yon, A Young Jung, Seul Gi Park, Sl Bi Chu, Lee Wha Gwon, Sang Yoon Nam Jan 2016

Postnatal Expression Profiles Of Phospholipid Hydroperoxide Glutathioneperoxidase In Spermatogenesis In Mice, Ki Youn Jung, Chunmei Lin, Jung-Min Yon, A Young Jung, Seul Gi Park, Sl Bi Chu, Lee Wha Gwon, Sang Yoon Nam

Turkish Journal of Veterinary & Animal Sciences

Phospholipid hydroperoxide glutathione peroxidase (PHGPx) is known to be an antioxidant enzyme that may be implicated in spermatogenesis, but its functional significance in the development of testes remains poorly understood. To demonstrate the roles of PHGPx in spermatogenesis during postnatal development, expression profiles of PHGPx mRNA and protein in testes and epididymides obtained from mice 1-9 and 27 weeks after birth were spatiotemporally analyzed. In testes, PHGPx mRNA first appeared in 2-week-old mice, while its protein was first detected in late spermatocytes and round spermatids from 3-week-old mice and levels were greatly increased in elongated spermatids and immature spermatozoa of …

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to investigate changes of serum testosterone, scrotal circumference, body weight, and semen characteristics in a Meat Institute Sheep (MIS) population during their developing period (between 3 and 17 months). Correlative relationships among parameters were also tested. Body weight and scrotal circumference were measured monthly, blood samples for testosterone levels were taken bimonthly (3-17 months), and semen samples were collected by an electroejaculator between the ages of 9 and 17 months. The analysis showed that the average serum testosterone levels ranged from 1.83 to 13.28 ng/mL and significantly depended on the age of the lambs …

Immunohistochemical Evaluation Of Canine And Felinemerkel Cell Tumors?A Report Of Two Cases, Mateusz Mikiewicz, Iwona Otrocka-Domagala, Katarzyna Pazdzior-Czapula, Michal Gesek, Anna Mikolajczyk, Agnieszka Blacha

Turkish Journal of Veterinary & Animal Sciences

Merkel cell tumors, a type of cutaneous round-cell tumors, are rarely observed in dogs and cats. This tumor type originates from cutaneous neuroendocrine cells. In the present study, the morphology of canine and feline Merkel cell tumors and their immunoexpression of neuron-specific enolase, cytokeratin, chromogranin A, Ki67, and metallothionein were evaluated using histopathological and immunohistochemical methods. The canine Merkel cell tumor displayed a diffuse morphological pattern, whereas the feline tumor displayed a solid morphological pattern. Both tumors were positive for neuron-specific enolase and cytokeratin, but negative for chromogranin A. The Ki67 indexes in the canine and feline tumors were 7% …

Comparison Of The Development Of Mouse Embryos Manipulatedwith Different Biopsy Techniques, Ali̇ Ci̇han Taşkin, Tolga Akkoç, Hakan Sağirkaya, Haydar Bağiş, Sezen Arat

Turkish Journal of Veterinary & Animal Sciences

Preimplantation genetic diagnosis is the detection of inherited diseases and the sex of embryos before implantation in the practice of human medicine as well as in veterinary medicine. The introduction of experimental animal embryo biopsy techniques has been a milestone in the developmental process of preimplantation genetic diagnosis techniques. The aim of the present study was to evaluate in vivo and in vitro development of embryos after biopsy in an experimental mouse model and to perform comparisons across different biopsy techniques (blastomere biopsy and trophectoderm biopsy). At the end of the study, no significant difference was observed between the blastomere …

Linking Vital Rates Of Landbirds On A Tropical Island To Rainfall And Vegetation Greenness, James F. Saracco, Paul Radley, Peter Pyle, Erin Rowan, Ron Taylor, Lauren Helton Jan 2016

Linking Vital Rates Of Landbirds On A Tropical Island To Rainfall And Vegetation Greenness, James F. Saracco, Paul Radley, Peter Pyle, Erin Rowan, Ron Taylor, Lauren Helton

Research outputs 2014 to 2021

Remote tropical oceanic islands are of high conservation priority, and they are exemplified by range-restricted species with small global populations. Spatial and temporal patterns in rainfall and plant productivity may be important in driving dynamics of these species. Yet, little is known about environmental influences on population dynamics for most islands and species. Here we leveraged avian capture-recapture, rainfall, and remote-sensed habitat data (enhanced vegetation index [EVI]) to assess relationships between rainfall, vegetation greenness, and demographic rates (productivity, adult apparent survival) of three native bird species on Saipan, Northern Mariana Islands: rufous fantail (Rhipidura rufifrons), bridled white-eye (Zosterops conspicillatus), and …

Why Fish Do Not Feel Pain, Brian Key Jan 2016

Why Fish Do Not Feel Pain, Brian Key

Animal Sentience

Only humans can report feeling pain. In contrast, pain in animals is typically inferred on the basis of nonverbal behaviour. Unfortunately, these behavioural data can be problematic when the reliability and validity of the behavioural tests are questionable. The thesis proposed here is based on the bioengineering principle that structure determines function. Basic functional homologies can be mapped to structural homologies across a broad spectrum of vertebrate species. For example, olfaction depends on olfactory glomeruli in the olfactory bulbs of the forebrain, visual orientation responses depend on the laminated optic tectum in the midbrain, and locomotion depends on pattern generators …

Cognitive Evidence Of Fish Sentience, Jonathan Balcombe Jan 2016

Cognitive Evidence Of Fish Sentience, Jonathan Balcombe

Animal Sentience

I present a little-known example of flexible, opportunistic behavior by a species of fish to undermine Key’s (2016) thesis that fish are unconscious and unable to feel. Lack of a cortex is flimsy grounds for denying pain to fish, for on that criterion we must also then deny it to all non-mammals, including birds, which goes against scientific consensus. Notwithstanding science’s fundamental inability to prove anything, the precautionary principal dictates that we should give the benefit of the doubt to fish, and the state of the oceans dictates that we act on it now.

Fish Lack The Brains And The Psychology For Pain, Stuart W.G. Derbyshire Jan 2016

Fish Lack The Brains And The Psychology For Pain, Stuart W.G. Derbyshire

Animal Sentience

Debate about the possibility of fish pain focuses largely on the fish’s lack of the cortex considered necessary for generating pain. That view is appealing because it avoids relatively abstract debate about the nature of pain experience and subjectivity. Unfortunately, however, that debate cannot be entirely avoided. Subcortical circuits in the fish might support an immediate, raw, “pain” experience. The necessity of the cortex only becomes obvious when considering pain as an explicitly felt subjective experience. Attributing pain to fish only seems absurd when pain is considered as a state of explicit knowing.

What Would The Babel Fish Say?, Monica Gagliano Jan 2016

What Would The Babel Fish Say?, Monica Gagliano

Animal Sentience

Starting with its title, Key’s (2016) target article advocates the view that fish do not feel pain. The author describes the neuroanatomical, physiological and behavioural conditions involved in the experience of pain in humans and rodents and confidently applies analogical arguments as though they were established facts in support of the negative conclusion about the inability of fish to feel pain. The logical reasoning, unfortunately, becomes somewhat incoherent, with the arbitrary application of the designated human criteria for an analogical argument to one animal species (e.g., rodents) but not another (fish). Research findings are reported selectively, and questionable interpretations are …

Modulation Of Behavior In Communicating Emotion, Martin Gardiner Jan 2016

Modulation Of Behavior In Communicating Emotion, Martin Gardiner

Animal Sentience

King discusses many examples where two animals, as they bond, behave in ways we interpret as expressing love for one another. If one of the bonded animals then dies, signs of loving are replaced by signs we interpret as expressing grief by the animal who remains. I propose a pathway for emotional communication between an animal and an observer that can have a central role in these and other observations by King and in our overall ability to interpret observed behavior in relation to emotion. This pathway provides evidence of emotion in an observed animal by communicating evidence of emotion’s …

Spinning Our Wheels And Deepening The Divide: Call For An Evidence-Based Approach To The Fish Pain Debate, Steven J. Cooke Jan 2016

Spinning Our Wheels And Deepening The Divide: Call For An Evidence-Based Approach To The Fish Pain Debate, Steven J. Cooke

Animal Sentience

There is vigorous ongoing debate about whether fish feel pain and have the capacity to suffer. The body of literature dedicated to the topic is increasing but what is particularly problematic is that the majority of the contributions represent opinion pieces and thus fall within the realm of advocacy. Many of the empirical research papers purporting that fish do or do not feel pain have problems with cavalier use of definitions, poor experimental design, or statistical/technical issues and tend to include advocacy statements in their interpretations. Rather than continuing to spin our wheels and deepen the divide, I would advocate …

The First Certified Record Of The Endemic Fish Speciespachychilon Macedonicum (Steindachner, 1892) In A Lake Complex Outsideof Its Nominal Range, With Notes On Its Biological Features, Dimitra Bobori, Olga Petriki, Emmanouel Tsakoumis

Turkish Journal of Zoology

The cyprinid Pachychilon macedonicum (Steindachner, 1892) is a species that is endemic to the southern Balkan Peninsula with limited distribution in Greece. Here we confirm the species' expansion and establishment in a complex of 4 lakes located outside of its currently known distribution range and provide, for the first time, some of its biological features. The species' presence was certified in 3 (Vegoritida, Petron, Chimaditida; northern central Greece) of the 4 lakes studied (Lake Zazari was also sampled), which now constitute a new western limit for its distribution in Greece. Pachychilon macedonicum specimens in Lake Vegoritida were longer (mean length: …
