Abstract Between October 2018 and 2019, seven megamouth sharks were reported as bycatch in the small-scale surface midwater gillnet fisheries operating from ports of Mancora Salaverry northern Peru. Here we present details these specimens events that represent first documented records this species Peruvian waters, confirming their occurrence bycatch. We recommend continued monitoring programs t...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
Commercial fishing constitutes an important food source but induces undesirable bycatch on animals worldwide. This study extends research geographically to the Western Pacific Ocean, filling a knowledge gap regarding and mitigation measures in region. Bycatch has caused many lethal consequences pantropical spotted dolphins ( Stenella attenuata ) during their interaction with fisheries area. We ...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
Various plastic strips and sheets (termed 'simple anterior fish excluders'-SAFEs) were positioned across the openings of penaeid trawls in attempts at reducing the unwanted bycatches of small teleosts. Initially, three SAFEs (a single wire without, and with small and large plastic panels) were compared against a control (no SAFE) on paired beam trawls. All SAFEs maintained targeted Metapenaeus ...
Based on an extensive sampling regime from both nesting populations and bycatch, frequency analyses of mitochondrial (mt) DNA control region haplotypes in the Mediterranean were used to assess the genetic structure and stock composition of the loggerhead sea turtle, Caretta caretta, in different marine fisheries. The analyses show the following. (i) In drifting longline fisheries working in Med...
Fisheries bycatch continues to drive the decline of many threatened marine species such as seabirds, sharks, mammals and sea turtles. Management frameworks typically address incidental catch with fleet-level controls on fishing. Yet, individual operators differ in their fishing practices efficiency at catching fish. If have differing abilities target, they should also avoid bycatch. We analysed...
