Why Is The Depletion Of Our Important Fish Stocks So Persistent?, James A. Wilson

Maine Policy Review

In the 1980s and 1990s, two events changed the fundamental structure of Maine's coastal ecology: inshore herring and then nearshore groundfish stocks were overfished and disappeared. Surprisingly, even without fishing, there has been no recovery. Standard fisheries management assumes that the recovery of any locally overfished place should be quick – fish from other places will 'fill in.'

In contrast, recent scientific work on social learning among animals suggests that fish have communication and learning abilities comparable to other vertebrates. Learning allows groups of fish to adapt to much more local places than possible if adaptation depended on genetics alone. …

A Call For Ethical And Responsible Treatment Of Invasive Species By Recreational Anglers, Kevin A. Adeli

Human–Wildlife Interactions

Invasive species pose a prominent threat to global biodiversity, with aquatic ecosystems being particularly susceptible. In an effort to limit the spread of aquatic invasive species, numerous public awareness programs have been launched, and several regions have enacted “must-kill” angling regulations, which prohibit the live release of invasive fish species when captured. Many education programs, however, demonize invasive species and lack any instruction for humane euthanasia. This unbalanced approach has translated into widespread mistreatment of invasive species among recreational anglers. This piece addresses these concerns by discussing their significance and providing recommendations for how education programs can adopt a more …

Exploring The Dynamics Of Small Pelagic Fish Catches In The Marmara Sea In Relation Tochanging Environmental And Bio-Optical Parameters, Eki̇n Akoğlu

Turkish Journal of Zoology

The Marmara Sea has a large drainage basin that includes cities with heavy industrialisation and agricultural land use. Therefore, it is under the influence of significant anthropogenic activities that adversely affect the well-being of its ecosystem. The Marmara Sea is also an important fishing ground with many commercially important fish species. These fish species are also under the influence of the adverse impacts of anthropogenic activities. Fisheries catches in the Marmara Sea had experienced severe fluctuations since the onset of the 2000s. In this study, possible underlying reasons for these fluctuations were investigated between 2000 and 2019 using remotelysensed environmental …

Exploring Scale In Ocean And Coastal Governance In The Wider Caribbean, Robin C. Mahon

Gulf and Caribbean Research

An early childhood attraction to the sea led to a career in marine ecology, fisheries and ocean and coastal governance. This paper tracks the development of my career from tertiary education, through a variety of jobs and positions with government, private sector, international and academic organizations. These positions took me from national to regional levels of governance, then down to local levels and ultimately back up to regional and global levels. At each stage new concepts join those already there to build what is ultimately a multilevel perspective on ocean and coastal governance. This perspective is built around ideas of …

Cointegration Analysis Of Wild And Farmed Sea Bream And Sea Bass Prices In Turkey, Mehmet Saltuk Arikan, Ahmet Cumhur Akin, Mustafa Bahadir Çevri̇mli̇, Mustafa Agah Teki̇ndal

Turkish Journal of Veterinary & Animal Sciences

Market integration is an indicator of the extent to which different products are interrelated, and the presence of market integration between products suggests that they are substitutes. The objective of this study was to determine the market interaction between wild and farmed products of two fish species, namely sea bream and sea bass. For this purpose, the relationship between the producer price time series of cultured sea bream, wild sea bream, cultured sea bass, and wild sea bass in the period of 2009-2017 was tested using the cointegration analysis technique. It was found that the wild sea bream and sea …

Fish Sentience, Consciousness, And Ai, Ila France Porcher

Animal Sentience

The systematic criticism of articles providing evidence that fish and invertebrates can feel pain is discussed. Beliefs are known to be stronger than evidence in the human mind, and could generate this outcry, while from another perspective, the criticisms appear as a territorial move by fishermen against a perceived threat to their domain. The scientific inconsistency in which consciousness is granted to machines but not to fish and invertebrates, purely due to political bias, is pointed out. No basis exists for denying sentience to any life form as long as science is ignorant of the nature and source of consciousness.

Management Of Double-Crested Cormorants To Improve Sport Fisheries In Michigan: Three Case Studies, Brian S. Dorr, Shauna L. Hanisch, Peter H. Butchko, David G. Fielder

Human–Wildlife Interactions

Impacts of double-crested cormorants (Phalacrocorax auritus) to fisheries have been documented, but evaluation of the process and outcomes of cormorant management to reduce impacts on fisheries is lacking. We provide a synthesis of adaptive management of double-crested cormorants in the Les Cheneaux Islands (LCI), Brevoort Lake, and Drummond Island, Michigan from 2004 to 2007. The LCI management focused on reducing numbers of nesting cormorants in the region as a means of improving the yellow perch (Perca flavescens) population and fishery. At Brevoort Lake and Drummond Island, management focused on lethal and nonlethal harassment of spring migrating …

Building A Sustainable Seafood System For Maine, Robin Alden

Maine Policy Review

In this article, Robin Alden notes that Maine could have one of the premier marine food systems in the world. However, that means adequate steward­ship of the Gulf of Maine ecosystem and diversifying the fishing industry beyond lobster by creating innovative public policy and a food system that supports community fishing.

Fisheries And Environmental Research By The Minnesota Sea Grant College Program, Donald C. Mcnaught

Journal of the Minnesota Academy of Science

ABSTRACT-Minnesota's Sea Grant College Program has funded research and outreach activities since 1977. Research results combined with public education setve the citizens, government, and businesses of the state. Research on commercial and sport fisheries, aquaculture, and environmental contamination is highlighted here. This article shows Sea Grant's contributions to understanding the Lake Superior ecosystem, including its chemical, biological, and human aspects.
