Monthly length-frequency data collected from artisanal fisheries from November 2013 to October 2014 were analyzed with FiSAT software using the ELEFAN package to estimate the population parameters of fishes. ...
Indonesia is the world’s largest archipelagic State with some 17 508 islands (of which 6 000 are inhabited), and 54 716 km of coastline, and the world’s fourth most populous nation (247.5 million). In 2012, Indonesia’s fishery production reached approximately 8.9 million tonnes, of which inland and marine catch accounted for about 5.8 million tonnes and aquaculture 3.1 million ...
If the water level has decreased more than 5 cm, the soil may be too permeable and therefore not suitable for pond construction Overview With good management, your fish should be ready to harvest within six to nine months after stocking. ...

This action mixes stratified water while increasing dissolved oxygen levels and protecting fish, aquatic organisms and beneficial microbes from suffocation. Beneficial Microbes Fishery Prime is a special blend of Probiotic microbes for the improvement of recreational fisheries. It is the first ever Probiotic for lake management. ...
And it has scientists, international fisheries managers, seafood and fishing industry businesses, and conservationists grappling with how to balance a lucrative krill industry with protection of what’s considered a key species for one of world’s most climate-sensitive ecosystems. ...

Where such mangroves are secured through appropriate management regimes, and where their fisheries are well managed they are likely to give greatest value. ...
Fisheries managers estimate that more than 120,000 fishermen in the three countries bordering the lake make their living from its waters. Wrecked breeding grounds A survey published last year by the Lake Victoria Fisheries Organization (LVFO), a management body within the intergovernmental East African Community, showed that ...
Mercury has been entering the environment from both natural and anthropogenic sources for millennia, and humans have been influencing its environmental transport and fate from well before the Industrial Revolution. Exposure to mercury (as neurotoxic monomethylmercury (MeHg)) occurs primarily through consumption of finfish, shellfish, and marine mammals, and regulatory limits for MeHg ...
Monitoring took place in areas under co–management fisheries administration provision entitled 'Management and exploitation areas for benthic resources (MEABR)' where several species that are under commercial exploitation have to be monitored. ...
Local governance based on institutions for collective action can help overcome social dilemmas in natural and agricultural resource management. A common path towards local governance is decentralisation, and within this context, a transfer of property rights from central government to local resource users. ...
Findings could help fishery and wildlife managers monitor their stocks before disaster strikes. ...
Climate change could benefit some Pacific fisheries, but tracking the success of adaptation needs effective monitoring, says Johann Bell. ...
Science is also being used to determine whether networks of protected areas improve wider biodiversity conservation and fisheries management. Traditionally, research has answered 'no' to this question, says Comley, but this is starting to change. ...
1998, SPF are concentrated in specific areas not influenced directly by these anomalies and therefore available to fishing in considerable abundance and vulnerable to a high fishing scheme. Our recommendation for SPF-fishery management is to regulate the fishing during these anomalously warm periods. Finally, it is important to investigate more about fishing ...
Economics for Fisheries Management, by R. Quentin Grafton, James Kirkley, Tom Kompas and Dale Squires. ...
The fisheries have also experienced the development of considerable overcapacity as a result of ineffective management and subsidies. Management of the fishery is complicated by the existence not only of multiple species and gears, but also multiple countries. Concerns about regional employment have also influenced ...
Many of the major species have been identified as being overfished or experiencing overfishing. Federal management is moving from single-species to multispecies to ecosystem-based fisheries management. In this paper, we present economic performance trends of US fisheries. We note a trend of declining landings and ex-vessel values ...
Fisheries managers and advisors in developing countries face challenges that may be difficult to overcome, because they use doctrines, principles and models of management and economics that do not adequately explain the problems that need to be solved. ...
