Does The Seal Licensing System In Scotland Have A Negative Impact On Seal Welfare?, Laetitia Nunny, Fritha Langford, Mark P. Simmonds Jan 2019

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

Mark P. Simmonds, O.B.E.

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 ...


The Shellfish Corner: Shellfish Aquaculture In The Commons, Michael A. Rice Mar 2018

The Shellfish Corner: Shellfish Aquaculture In The Commons, Michael A. Rice

Michael A Rice

The major common denominator of shellfish aquaculture in coastal or estuarine waters worldwide is that most culture operations are conducted in common or public trust waters, necessitating constant interaction in the political arena with other competing interests. As a matter of practicality, the best systems for managing aquaculture lease policy in an equitable manner are on a local enough scale to facilitate stakeholder involvement, and to allow aquaculturists to organize into professional trade organizations so that the collective interest of the industry is heard in the process.


The Shellfish Corner: Cap And Trade Systems With Shellfish May Be Good For The Economic Bottom Line, Michael A. Rice Dec 2017

The Shellfish Corner: Cap And Trade Systems With Shellfish May Be Good For The Economic Bottom Line, Michael A. Rice

Michael A Rice

The development of a traditional form of Integrated Multi-Trophic Aquaculture (IMTA) in the Dagupan City Estuary system in the Philippines is based upon different producers each focusing on individual species rather than individual producers producing multiple species with very different market values. The long-term success of such a system requires attention to local marine spatial planning and enforcement of caps on forms of feed-based (net pen or fish cage) aquaculture systems.


Rational Ecosystems-Based Fisheries Management, Rajesh Singh, Quinn Weninger Sep 2017

Rational Ecosystems-Based Fisheries Management, Rajesh Singh, Quinn Weninger

Quinn Weninger

Ecosystem-based fisheries management (EBFM) seeks to incorporate the full complexity of marine ecosystems into the design of fisheries management policies and regulations. This paper presents a model of a multiple-species, and spatially-temporally heterogeneous fishery that is managed under a tradable quota regulation. Past studies of fisheries management in this setting have, for purposes of simplification, resorted to (1) restrictive assumptions for multiple-species harvesting technologies, (2) myopic and ad hoc behavioral rules for the fishing sector, and (3) assumptions for regulatory control that do not exist in real world fisheries. We derive a rational expectations, ecological-economic equilibrium outcome for harvests, discards ...


Pain Perception In Fish: Evidence And Implications For The Use Of Fish, Lynne U. Sneddon Aug 2015

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

Lynne U. Sneddon, Ph.D.

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 ...


Animal Welfare Perspectives On Recreational Angling, Steven J. Cooke, Lynne U. Sneddon Jul 2015

Animal Welfare Perspectives On Recreational Angling, Steven J. Cooke, Lynne U. Sneddon

Lynne U. Sneddon, Ph.D.

Fish captured by recreational anglers are often released either voluntarily or because of harvest regulations in a process called ‘‘catch-and-release’’. Catch-and-release angling is thought to be beneficial for the conservation of fish stocks based on the premise that most of the fish that are released survive. However, expanding interest in animal welfare has promoted debate regarding the ethics of catch-and-release angling. There is a growing recognition that fish can consciously experience nociception and that they have some capacity to experience pain and fear. Indeed, empirical anatomical, physiological, and behavioural evidence supports the notion that fish could experience these two forms ...


Differences In Response To Hypoxia In The Three-Spined Stickleback From Lotic And Lentic Localities: Dominance And An Anaerobic Metabolite, L. U. Sneddon, J. Yerbury Jun 2015

Differences In Response To Hypoxia In The Three-Spined Stickleback From Lotic And Lentic Localities: Dominance And An Anaerobic Metabolite, L. U. Sneddon, J. Yerbury

Lynne U. Sneddon, Ph.D.

Dominance hierarchies of the three-spined stickleback Gasterosteus aculeatus from river and pond populations were subjected to hypoxia (20%, range±1%). Under hypoxia, the hierarchies were less stable in terms of rank position and tissue L-lactate was higher in river fish than pond fish under normoxia and hypoxia. Dominant fish gained mass under normoxia but lost mass under hypoxic conditions possibly due to them maintaining high levels of aggression.

The Shellfish Corner--Shellfish Sanitation And The Price Of Shellfish, Michael A. Rice Jan 2015

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 Dec 2014

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, O.B.E.

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 ...

Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra Aug 2014

Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra

Ganesh Chandra

Assam is endowed with copious aquatic wealth in the form of beels, swamps, ponds and rivers. The floodplain wetlands (beels) extending over one lakh hectare, constitute the most important fishery resource of the state. The beels are considered as one of the most productive ecosystems owing to their characteristic interactions between land and water system. These wetlands are the common property resource and under different management regimes. These wetlands are under various management regimes, i.e., private management (individuals and groups), fishermen cooperative management, Community-based fisheries management (decentralized management, Government works as facilitator) and open access. Most of the unregistered ...


Extension Programming In Support Of Public Policy For The Management Of Aquaculture In Common Water Bodies, Michael A. Rice Jun 2014

Extension Programming In Support Of Public Policy For The Management Of Aquaculture In Common Water Bodies, Michael A. Rice

Michael A Rice

Many countries of Asia, including Indonesia, have experienced the problem of hypoxic fish kills among fish in netpens and fish corrals in various publicly-held water bodies. Fish farming in enclosures in public water bodies attractive because of low overhead costs in comparison to farming the identical species in constructed ponds. But aerobic bacterial degradation of feed and fish feces in common waters can lead to oxygen depletion, thus causing fish kills. Mass-balance and ecological carrying capacity models and education through and extension programming can be used to inform policy makers as to the maximum biomass of farmed fish allowable before ...

Use Of Communication Media In Wetland Fisheries Development Of Assam, Ganesh Chandra

Ganesh Chandra

The study was carried out in 21 districts of Assam. Two categories of respondents, namely fishers (106 nos) of floodplain wetlands and lower level field extension functionaries (30 officials) constituted the sample for the study. The study revealed that the interpersonal communication sources like consultation with Fisheries Extention Officer Beel manager and scientists were the most important sources for obtaining information on new, improved practices. Demonstration and consultation with progressive farmers were assigned second and third rank. Field extension functionaries preferred group discussion as the main source of extension programme followed by demonstration, fisheries publication and field day/ fish farmers ...

Participatory Rural Appraisal, Ganesh Chandra Apr 2010

Participatory Rural Appraisal, Ganesh Chandra

Ganesh Chandra

Participation, empowerment and inclusion have become the new development buzzword. There has been a range of interpretations of the meaning of participation in development. Participatory development starts from the premise that it is important to identify and build upon strengths already present in communities. Perhaps the most widespread appearance of participation in mainstream development has been seen in the form of participatory methodologies of research, intended to gather a wide range of information from local people at their livelihoods, needs, and strengths, at the same time as 'empowering' them through a process of collaborative analysis and learning. PRA is a ...


Dissemination Of Communication And Information In Inland Fisheries, Ganesh Chandra Apr 2010

Dissemination Of Communication And Information In Inland Fisheries, Ganesh Chandra

Ganesh Chandra

Flow of communication and information from the research station to the end user is sine qua non for the sustainable production as well as productivity enhancement in inland fisheries and the development of fishers as a whole. The resource poor who are often more in need than others of information on sustainable and low external input technologies is least likely to gain access to the information required. This has been seen particularly in the fisheries sector where the channels of information accessible to the resource poor delivered information on new practices and recommendations as well as the new culture technologies ...

Evaluation Of Frontline Demonstration Of Greengram (Vigna Radiata L.) In Sundarbans, West Bengal, Ganesh Chandra

Ganesh Chandra

Green gram (mungbean) is one of the important pulse crop in India, which plays a major role in augmenting the income of small and marginal farmers of Sundarban. The prevalent farming situation in Sundarban areas being characterised by kharif season with paddy cultivation in rain-fed condition and water requirement for growing rabi and summer crops are met only through residual soil moisture and/or stored rain-water. The low production of traditional varieties of greengram was a cause of concern for the farmers at large. To overcome this problem of low yield, Krishi Vigyan Kendra of CIFRI has conducted frontline demonstration ...

Stock Enhancement And Its Impact On The Productivity Of Haribhanga Beel In Assam, Ganesh Chandra Jan 2009

Stock Enhancement And Its Impact On The Productivity Of Haribhanga Beel In Assam, Ganesh Chandra

Ganesh Chandra

The floodplain wetlands (beels), extending over one lakh hectare, constitute the most important fishery resource of the Assam. The average productivity of Assam beels is 150-200 kg./ha/year. Many factors can be attributed for this situation, but inadequate auto stocking might be one of the basic reasons. To tide over this situation, rearing of seed in pens could be a viable alternative. Stock enhancement through pen culture was demonstrated by CIFRI at Haribhanga beel with three IMC. The fisher has adopted with modification using three Indian major carp and three exotic carp. A pen enclosure of 5000 m2 has ...
