This article presents a brief summary of Chile's fisheries and aquaculture sectors. It also addresses the main institutions and guilds since the time when there were no regulations until now, where overfishing has lead to the need for regulations through close…

This report from the United Nations conference on trade and development looks at trade, value addition and social inclusiveness in the Gambian fisheries sector, with a focus on women.

This report by Future of Fish (FoF) represents the first stage of an approach solving complex systemic problems in aquaculture. The insights gleaned through this research and analysis will allow FoF to recruit and convene a working group of entrepreneurs, exis…

Increases in atmospheric carbon dioxide drive accompanying changes in the marine carbonate system as carbon dioxide enters seawater and alters ocean pH. As such changes do not occur in isolation, and other environmental factors have the potential to modulate t…

Low oxygen zones in coastal and open ocean ecosystems have expanded in recent decades, a trend that will accelerate with climatic warming. Christopher J. Gobler et al, Stony Brook University, US, experimentally assessed the consequences of hypoxic and acidifie…

By adjusting water discharges in ways designed to boost salmon productivity, officials at a dam in central Washington were able to more than triple the numbers of juvenile salmon downstream of the dam over a 30-year period, according to a study published in th…

Fisheries bycatch of marine animals has been linked to population declines of multiple species, including many sea turtles. John Wang et al, University of Hawaii, examined the effectiveness of illuminating gillnets with ultraviolet (UV) light-emitting diodes f…

Introduction The anthropogenic increase in atmospheric CO2 concentration is a major environmental concern. One alarming consequence is a rapid change in seawater chemistry and decrease of ocean pH (Solomon et al. 2007; Doney et al. 2009), which could have larg…

Introduction Marine protected areas (MPAs) have received increasing attention as tools in fisheries management and conservation. However, examples of replicated experiments that sampled organismal density before and after establishment of MPAs at sites both in…

Aquaculture is replacing capture fisheries in supplying the world with dietary protein. Although disease is a major threat to aquaculture production, the underlying global epidemiological patterns are unknown. Tommy Leung, University of New England, and Amanda…

A genetic linkage map has been constructed for Atlantic halibut on the basis of 258 microsatellites and 346 AFLPs. Twenty-four linkage groups were identified, consistent with the 24 chromosomes seen in chromosome spreads. The total map distance is 1562.2 cM in…

As the global average temperature increases and CO2 within the ocean begins to reach saturation the ability of the ocean to absorb carbon will alter significantly, writes J. P. Hickey, School of Natural and Built Environs, University of South Australia.

This article looks at the life history and habitat characteristics of the Atlantic halibut. By Luca M. Cargnelli, Sara J. Griesbach, and Wallace W. Morse, National Marine Fisheries Service.
