We construct a catch per unit effort (CPUE) index for minke whales caught in the E-areas of north-eastern Atlantic, adjusted for boat efficiency and spatial effects. The index is interpreted as an unsmoothed relative index of abundance, also including variation in catch conditions due to weather, migration and local clustering of minke whales. Norwegian minke whaling was interrupted from 1984 t...

Co-management agreements, whereby community rules for the management of local floodplain lake fisheries are legalised and enforced by the government, have become common in the lower Amazon. Agreements are intended to limit exploitation, in particular by commercial boats, to raise stock abundance and fisheries productivity for the benefit of local subsistence-oriented fishers and for conservatio...

This study aimed to determine the impact of hook and bait type on catch composition per unit effort. Effects types composition, effort (CPUE), length weight distributions in demersal longline fishery were determined by experimental surveys sets Aegean Sea. A total 12 samplings corresponding 4800 fishing performed between April 2014 September 2014. Two types; sardine (Sardina pilchardus) grooved...

The sturgeon stock assessment was performed to aim at estimation of absolute and relative abundance and determination of species composition at lower 10 m depths using the Si-Sara2 RV vessel in the Iranian coasts of the Caspian Sea in Guilan, Mazandaran and Golestan provinces during 6-30 September 2011-2012. In this study, 40 stations were selected on the basis of stratified random sampling des...
