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 in the spinal cord throughout vertebrate phylogeny, from fish to humans. Here I delineate the region of the human brain that is directly responsible for feeling painful stimuli. -
Virtual Population Analysis
1 INTRODUCTION 1.1 OVERVIEW There are a variety of VPA-type methods, which form powerful tools for stock assessment. At first sight, the large number of methods and their arcane names can put off the newcomer. However, this complexity is based on simple common components. All these methods use age-structured data to assess the state of a stock. The stock assessment is based on a population dynamics model, which defines how the age-structure changes through time. This model is the simplest possible description of numbers of similar aged fish where we wish to account for decreases in stock size through fishing activities. The diversity of VPA methods comes from the way they use different types of data and the way they are fitted. This manual is structured to describe the different components that make up a VPA stock assessment model: Population Model (Analytical Model) The population model is the common element among all VPA methods. The model defines the number of fish in a cohort based on the fishing history and age of the fish. A cohort is a set of fish all having (approximately) the same age, which gain no new members after recruitment, but decline through mortality. The fisheries model attempts to measure the impact catches have on the population. The population model usually will encapsulate the time series aspects of change and should include any random effects on the population (process errors), if any. Link Model Only rarely can variables in which we are interested be observed directly. Usually data consists of observations on variables that are only indirectly linked to variables of interest in the population model. -

Animal Sentience 2016.011: Brown Commentary on Key on Fish Pain Comparative evolutionary approach to pain perception in fishes Commentary on Key on Fish Pain Culum Brown Biological Sciences Macquarie University Abstract: 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 understanding of evolutionary processes. Keywords: pain, fishes, behaviour, physiology, nociception Culum Brown [email protected] studies the behavioural ecology of fishes with a special interest in learning and memory.

Guidelines for the Use of Fishes in Research
Reference Resources Caveats from AAALAC’s Council on Accreditation regarding this resource: “Guidelines for the Use of Fishes in Research” Use of Fishes in Research Committee (joint committee of the American Fisheries Society, the American Institute of Fishery Research Biologists, and the American Society of Ichthyologists and Herpetologists), 2014. *This reference was adopted by the Council on Accreditation with the following four clarifications: Clarifications: #1. On page 27, the Guidelines for the Use of Fishes in Research state that “[t]he preferred method for archival storage is direct immersion in a 10% formalin (3.7% formaldehyde) solution, followed by transfer to alcohol (70% ethanol, un-denatured preferred) for long-term preservation and storage, as with voucher specimens.” The document goes on to state later in the same paragraph that “[w]hen study interests demand that specimens be fixed without prior treatment with sedatives, the specimens can be numbed in ice water, or for small fishes, immersed directly in liquid nitrogen (see section 8.1 Euthanasia).” In these instances, death is either by fixation in a formalin solution or by freezing in liquid nitrogen, which are both considered unacceptable as a primary means of euthanasia by the AVMA. AAALAC International utilizes the AVMA Guidelines on Euthanasia and recommends this document, and applicable legal requirements be referred to for further guidance. #2. On page 6, the Guidelines for the Use of Fishes in Research discuss mortality as an experimental endpoint. The Guide emphasizes that studies should include descriptions of appropriate humane endpoints or provide science-based justification for not using a particular, commonly accepted humane endpoint. -
An Assessment of Recent Trade Law Developments from an Animal Law Perspective: Trade Law As the Sheep in Wolf's Clothing?
AN ASSESSMENT OF RECENT TRADE LAW DEVELOPMENTS FROM AN ANIMAL LAW PERSPECTIVE: TRADE LAW AS THE SHEEP IN WOLF’S CLOTHING? By Charlotte Blattner* Further development within the field of animal law seems to be at an impasse, lost among the potential paths presented by its traditional influ- ences: international treaty law, domestic animal welfare regulations, and trade law. First, classical elements of global animal treaty law are limited to preservationist aspirations, insusceptible to the questions of how animals are treated or how they cope with their environment. Second, animal welfare regulation is understood as a matter confined to national territories. In cross-border dialogue, animal matters have been reduced to allegations of imperialism, which is not conducive to furthering animal interests. Third, animals are regarded as commodities in international trade law, rendering their regulation an undesirable barrier to trade. These present deficiencies deprive global animal law of its significance as a dynamic instrument re- sponsive to global challenges, be they ethical, environmental, economic, technological, or social in nature. The objective of this paper is to demonstrate future ways out of this impasse. Recent developments in trade law, as demonstrated by four exam- ples found within the World Trade Organization’s (WTO) ‘case law,’ mark an important development for animal law. State objectives expressed through trade law are slowly moving away from anthropocentric considera- tions (i.e., geared to preserve a fraction of animals for human interests) to- wards sentiocentric animal welfare (i.e., aimed at minimizing animal suffering and focusing on animal interests). Thereby, the quality of animal law that developed on the international scene through trade law exceeded the status quo of global animal treaty law. -

Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota
CoaStalUpwellinO' and Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota Abstract /1 Theseasonal intensity of wind-induced coastal upwelling in the western Indian Ocean is investigated. The upwelling off Northeast Somalia stands out as the dominant upwelling feature in the region, producing by far the strongest seasonal upwelling pulse that exists as a; regular feature in any ocean on our planet. It is surmised that the productive pelagic fish habitat off Southwest India may owe its particularly favorable attributes to coastal trapped wave propagation originating in a region of very strong wind-driven offshore trans port near the southern extremity of the Indian Subcontinent. Effects of relatively mild austral summer upwelling that occurs in certain coastal ecosystems of the southern hemi sphere may be suppressed by the effects of intense onshore transport impacting these areas during the opposite (SW Monsoon) period. An explanation for the extreme paucity of fish landings, as well as for the unusually high production of oceanic (tuna) fisheries relative to coastal fisheries, is sought in the extremely dissipative nature of the physical systems of the region. In this respect, it appears that the Gulf of Aden and some areas within the Mozambique Channel could act as important retention areas and sources of i "see6stock" for maintenance of the function and dillersitv of the lamer reoional biolooical , !I ecosystems. 103 104 large Marine EcosySlIlms ofthe Indian Ocean - .

ICELAND, WHALING and ECOSYSTEM - BASED FISHERY MANAGEMENT
ICELAND, WHALING and ECOSYSTEM - BASED FISHERY MANAGEMENT PETER CORKERON Iceland, whaling and ecosystem-based fishery management. Peter Corkeron Ph.D. http://aleakage.blogspot.com/ 1 Introduction Icelanders look to the sea, and always have. Fishing has always been important to them, and they have a good record of attempting to ensure that their fisheries are sustainable. As the Icelandic Ministry of Fisheries stated in a declaration on 17th October 2006, “The Icelandic economy is overwhelmingly dependent on the utilisation of living marine resources in the ocean around the country. The sustainability of the utilisation is therefore of central importance for the long-term well being of the Icelandic people. For this reason, Iceland places great emphasis on effective management of fisheries and on scientific research on all the components of the marine ecosystem. At a time when many fish stocks around the world are declining, or even depleted, Iceland's marine resources are generally in a healthy state, because of this emphasis. The annual catch quotas for fishing and whaling are based on recommendations by scientists, who regularly monitor the status of stocks, thus ensuring that the activity is sustainable.”. Fisheries account for approximately 40% of the value of Iceland’s exported goods and exported services, and roughly two-thirds of Iceland's exported goods, minus services. Fisheries and fish processing account for little under 10% of Iceland’s Gross Domestic Product (GDP), down from more than 15% in 1980. With a population of just over 300,000 in 2007, Iceland is the world’s 178th largest nation, but in 2002 it was still ranked as the world’s 13th largest fisheries exporter. -
How Fisheries Policy Can Address Shifting Fish Stocks (PDF)
OCTOBER 2020 FS: 20-10-B FACT SHEET ON THE MOVE: HOW FISHERIES POLICY CAN ADDRESS SHIFTING FISH STOCKS Our ocean is undergoing rapid transformations due to climate change, including rising acidity, shifting currents, and warming waters.1 Fish, which are cold blooded and temperature sensitive, are responding by moving to cooler waters.2 The scale of this mass migration is striking. At least 70 percent of the commonly caught fish stocks along the U.S. Atlantic coast have shifted north or to deeper waters over the past 40 years.3 If climate change continues at its current rate, scientists predict some fish assemblages in the United States will have moved up to 1,000 miles by the century’s end.4 © OceanAdapt The distribution of Black Sea Bass biomass in 1972 and 2019. © Brenda Gillespie/chartingnature.com For more information, please contact: www.nrdc.org Lisa Suatoni www.facebook.com/NRDC.org [email protected] www.twitter.com/NRDC These changes have come so rapidly that they are outpacing For example, in less than a decade, spiny dogfish along fisheries science and policy. Climate-driven range shift the Atlantic coast went from a minor fishery to one creates a series of novel challenges for our fisheries netting 60 million pounds a year—without triggering any management system. Federal fisheries policy must adapt regulatory oversight. The result was overharvesting and and respond in order to ensure sustainability, preserve jobs, the eventual implementation of stringent catch limits that and maintain this healthy food supply. These challenges can put gillnetters and fish processors out of work.8 Likewise, be dealt with by improving federal fisheries policy in several a fishery developed seemingly overnight for a small forage specific ways: fish called chub mackerel, without any stock assessment or information on sustainable catch levels. -
“But It's Just a Fish”: Understanding the Challenges of Applying the 3Rs
animals Article “But It’s Just a Fish”: Understanding the Challenges of Applying the 3Rs in Laboratory Aquariums in the UK Reuben Message * and Beth Greenhough School of Geography and the Environment, University of Oxford, Oxford OX1 2JD, UK; [email protected] * Correspondence: [email protected] Received: 29 October 2019; Accepted: 28 November 2019; Published: 3 December 2019 Simple Summary: Fish are widely used in research and some species have become important model organisms in the biosciences. Despite their importance, their welfare has usually been less of a focus of public interest or regulatory attention than the welfare of more familiar terrestrial and mammalian laboratory animals; indeed, the use of fish in experiments has often been viewed as ethically preferable or even neutral. Adopting a social science perspective and qualitative methodology to address stakeholder understandings of the problem of laboratory fish welfare, this paper examines the underlying social factors and drivers that influence thinking, priorities and implementation of fish welfare initiatives and the 3Rs (Replacement, Reduction and Refinement) for fish. Illustrating the case with original stakeholder interviews and experience of participant observation in zebrafish facilities, this paper explores some key social factors influencing the take up of the 3Rs in this context. Our findings suggest the relevance of factors including ambient cultural perceptions of fish, disagreements about the evidence on fish pain and suffering, the language of regulators, and the experiences of scientists and technologists who develop and put the 3Rs into practice. The discussion is focused on the UK context, although the main themes will be pertinent around the world.
