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...

A new gillnet made from multiple mesh sizes ranging 125 to 180 mm of stretched (experimental gillnet) was tested under commercial fishing conditions compare the performance with that conventional gillnets a opening (control gillnet). Catch efficiency and size selectivity between two types were evaluated throughout one year in three different locations waters Vietnam. Experimental caught narrow-...

Fishes are one of the most commonly introduced aquatic taxa worldwide, and invasive fish species pose threats to biodiversity and ecosystem function in recipient waters. Considerable research efforts have focused on predicting the invasibility of different fish taxa; however, accurate records detailing the establishment and spread of invasive fishes are lacking for large numbers of fish around ...

In the Hawaii-based longline fishery, changes in fishing operations to target different species produce changes in the effectiveness of fishing effort units. Catch-per-unit-effort (CPUE) indices used in resource monitoring were improved by segregating dissimilar types of fishing effort. Cluster analysis was used to classify longline sets in relation to species composition of the catches. Based ...

In this study it is aimed that determining effect of some social and demographic properties on Catch Per Unit Effort (CPUE) in Uluabat Lake anglers. A total 375 interview applied with angler from April – 2015 to May 2016 monthly period. Mean CPUE values each was estimated as 1.36 fish/hr (0.08-5.67). Generalized additive models (GAMs) used for evaluating the data set. Variables model were age (...

The purpose of this study is to determine the effect escape gap cylinder folding trap on catch per unit effort (CPUE), rate, composition, and size fish caught in coastal waters Tuban Regency. research was conducted November 2019 by deploying 60 units ten experimental fishing trips at different locations. traps were 20 without gap, with an 3 cm x 6 cm, 4 7 cm. Overall, experiments resulted a col...
