Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries, 2020 The study was conducted at 0-30 meters depth, in the Northern Aegean coast of Turkey, between October 15, 2015 - October 15, 2017. In the study, 9 different gillnets (Mullet nets) having 18-20-22 mm mesh size and 0.35-0.50-0.65 hanging ratio were used ...

The Use of Gillnets for Estimation of Fish Stocks [PDF]
Journal of Animal and Veterinary Advances, 2010 In this research it has been targeted to estimate fishable stocks of Karakaya Dam Lake (in Turkey) by using fishing with gillnets method that had been suggested as an alternative method for estimating fish stocks. Productivity per hectare in the dam lake and the amount of fishable stocks has been calculated to be 13.67 kg ha-1 and 312.005 kg year-1 ...

Frontiers in Marine Science, 2018 There is widespread evidence that small-scale fisheries (SSF) bycatch threatens many populations of small cetaceans, yet conservation efforts are often limited by a lack of basic knowledge regarding their abundance, distribution, and habitat use.

Gillnet selectivity for the north African catfish, Clarias gariepinus (Actinopterygii: Siluriformes: Clariidae), from the Upper Okavango Delta, Botswana [PDF]
Acta Ichthyologica et Piscatoria, 2015 Background. Successful fisheries management requires estimation of gillnet selectivity for optimum exploitation of the resource. In the Okavango Delta, no study has assessed the selectivity of gillnets for Clarias gariepinus (Burchell, 1822) which is an ...
