Most statistical information on fish catch in Ghana and that of many other African countries are deficient in supporting effective fisheries management. Fish catches were examined between January 2009 and December 2010, to enhance the management of small-scale fisheries of Ghana. The methods employed were: Fish Catch Assessment (FCA) and documents analyses. The case study focused on four import...

We report an eight years female child with clinical and molecular cytogenetic findings consistent with CATCH 22 syndrome characterized by cardiac defect, typical facial dysmorphism, mental deficiency and chromosome 22 q11.2 deletion. Interphase FISH with 22q 11.2 probe demonstrated hemizygous deletion in 98.5% nuclei. Interphase FISH for diagnosis of CATCH 22 syndrome has not been reported prev...

—Catch-and-release fisheries have become very important in the management of overexploited recreational fish stocks. Tag return studies, where the tag is removed regardless of fish disposition, have been used to assess the effectiveness of restoration efforts for these fisheries. We extend the instantaneous rate formulation of tag return models to allow for catch and release as well as harvest....

Fishing gears have negative impacts on seafood quality, especially on fish in the mixed trawl fishery targeting Norway lobster (Nephrops norvegicus). In this fishery, which is worth about €80 millions in Denmark alone, the quality of fish can be significantly improved by simple gear changes. A trawl codend divided into an upper and lower codend was designed to separate fish from Norway lobster ...

Commercial fishing is a dangerous occupation despite decades of regulatory initiatives aimed at making it safer. We posit that rights-based fisheries management (the individual allocation of fishing quota to vessels or fishing entities, also called catch shares) can improve safety by solving many of the problems associated with the competitive race to fish experienced in fisheries around the wo...

Manage. 26:14–22. We examined fish populations, limnological conditions, lake basin morphology and watershed characteristics to evaluate patterns in population characteristics of ecologically important fish sp...

The dolphinfish (Coryphaena hippunis) is a highly migratory pelagic species commercially exploited by industrial, artisanal and recreational fisheries in tropical and subtropical areas of the world's oceans. Herein, we evaluated the dolphinfish industrial fishery in Pacific Panama for the first time generating a growth model and examining fluctuations in annual total catch and in catch per unit...

Marine protected areas (MPAs) have become a common conservation and management tool for reducing exploitation from the commercial and recreational fisheries sectors. However, the recreational fisheries sector has the potential to be compatible with no-take MPAs when catchand-release angling is practiced because, in theory, no fish are actually harvested. This presumes that the effects of catch-...
