Risk Assessment Of Catch And Release, Rolf Erik Olsen, Tor Fredrik Næsje, Trygve Poppe, Lynne Sneddon, John Webb

Lynne Sneddon, PhD

The report was produced during most of 2009, and gives a state of art overview of current knowledge on the effects of catch and release practices on these fish species’ welfare, using accessible and peer reviewed published literature as basis for the assessment. Anecdotic and non-published reports have been used to a limited extent as they are regarded as untested or containing unverified statements. The Panel on Animal Health and Welfare discussed the full report in a meeting on the 9th of December, and gave its support to the conclusions drawn by the ad hoc-group. The report has concentrated on …

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

Lynne Sneddon, PhD

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 …

Does The Seal Licensing System In Scotland Have A Negative Impact On Seal Welfare?, Laetitia Nunny, Fritha Langford, Mark P. Simmonds

Mark P. Simmonds, OBE

This study examined the licensing system that permits seal shooting in Scotland, which was established under Part 6 Conservation of Seals of the Marine (Scotland) Act 2010. Four approaches were used: data were collated and analyzed from both the Scottish Government and Scottish Marine Animal Stranding Scheme; a survey was sent to current license holders and informal interviews were conducted with key stakeholder types. Between February 2011 and the end of October 2015, 1229 gray seals, and 275 common seals were reported shot under license to the Scottish Government. The numbers of seals reported as shot has reduced year-on-year since …

Pain Perception In Fish: Evidence And Implications For The Use Of Fish, Lynne U. Sneddon

Lynne Sneddon, PhD

Pain assessment in fish is particularly challenging due to their evolutionary distance from humans, their lack of audible vocalization, and apparently expressionless demeanour. However, there are criteria that can be used to gauge whether pain perception occurs using carefully executed scientific approaches. Here, the standards for pain in fish are discussed and can be considered in three ways: neural detection and processing of pain; adverse responses to pain; and consciously experiencing pain. Many procedures that we subject fish to cause tissue damage and may give rise to the sensation of pain. Fish are popular as pets, in animal exhibits, and …

The Shellfish Corner--Shellfish Sanitation And The Price Of Shellfish, Michael A. Rice

Michael A Rice

Prices of raw molluscan shellfish in different countries around the world are tied to perceived risk of becoming ill if consumed. Wholesale prices of oysters in the southern New England from 1880 to 2010 are analyzed in relation to introduction of flush toilets and sewer systems in the early 20th Century, the initiation of the US National Shellfish Sanitation Program in 1925 and renewed consumer interest in consuming raw shellfish in the latter half of the 20th Century.

Interactions Between Short-Beaked Common Dolphin (Delphinus Delphis) And The Winter Pelagic Pair-Trawl Fishery Ff Southwest England (Uk), Marijke N. De Boer, James T. Saulino, Mardik F. Leopold, Peter J.H. Reijnders, Mark P. Simmonds

Mark P. Simmonds, OBE

During offshore and onshore studies (2004 to 2009), the interactions between pair-trawls and short-beaked common dolphins (Delphinus delphis) were studied to better understand the impact of bycatch. A ‘hotspot’ area where pair-trawls overlapped with high dolphin abundance was identified. We made comparisons between boat-based data collected in absence and presence of pair-trawlers. The relative abundance and group-size of dolphins was significantly higher in the presence of pair-trawlers. Dolphins were observed associating with towing and hauling procedures. Significantly, more carcasses occurred in areas with hauling-activity than those without. Body-temperatures obtained from carcasses found near operating pair-trawlers indicated that bycatch mostly occurred …

Climate Change Adaptation Chapter: Marshfield, Massachusetts, Joshua H. Chase, Jonathan G. Cooper, Rory Elizabeth Fitzgerald, Filipe Antunes Lima, Sally R. Miller, Toni Marie Pignatelli

Sally Miller

Climate change, understood as a statistically significant variation in the mean state of the climate or its variability, is the greatest environmental challenge of this generation (Intergovernmental Panel on Climate Change, 2001). Marshfield is already being affected by changes in the climate that will have a profound effect on the town’s economy, public health, coastal resources, natural features, water systems, and public and private infrastructure. Adaptation strategies have been widely recognized as playing an important role in improving a community’s ability to respond to climate stressors by resisting damage and recovering quickly. Based on review of climate projections for the …

Aquaculture, Michael Rice

Michael A Rice

This is the chapter on small-scale aquaculture within a volume intended as a guide for practitioners engaged in sustainable rural livelihood and food production projects in the developing world. Included in this chapter on aquaculture are fundamentals of aquaculture water quality, selection of sites and construction methods for fish ponds, and management techniques for carp and tilapia which are nutritious and easy to grow in artisanal ponds. The fundamentals of cage culture of fish is also covered, along with the fundamentals of culturing oysters and other molluscan shellfish in coastal waters.
