Summary: The size selectivity of alternative codends for nylon shrimp and yellow squat lobster was studied off the Chilean coast using the covered codend technique. Various mesh sizes (47 and 63mm mesh opening) and shapes ...

The behaviour of fish by-catch was recorded and characterized by in situ observations in the mouth of a crustacean trawl using an underwater camera system with artificial light, at depths between 106 and 461 m, along the ...

A monthly characterization of Chilean hoki aggregations was done using acoustic records obtained with SIMRAD EK60 and ES60 devices aboard three multipurpose vessels that operated in the central-southern fishery unit during ...

A new bottom trawl was designed and evaluated for the crustacean fisheries of central Chile using both dynamic simulation and model testing methods. First, a dynamic simulation of the trawl was evaluated using DynamiT ...

The behaviour of Chilean hake (Merluccius gayi gayi) in a bottom trawl was observed with an underwater camera positioned in the trawl mouth and in the front of the codend extension. Significant differences were observed ...

The evaluation of square mesh escape panels in bottom trawl nets used in the common hake fishery was carried out employing two complementary methodologies: top cover and alternated hauls. The top cover hauls were used to ...

Summary: To determine the selectivity of gillnets in the Chilean artisanal fishery for the Chilean hake Merluccius gayi gayi, an experimental net was used with three mesh sizes (5.2, 6.8 and 7.6 cm). A total of 2279 specimens ...

Tests were carried out in an attempt to determinine the moment at which the trawl gear utilized in demersal crustacean fisheries came into effective contact with the bottom. Results of the determination permit clear ...

The species composition and bycatches of a new trawl for crustaceans (Heterocarpus reedi, Cervimunida johni and Pleuroncodes monodon) was studied in central Chile between 2007 and 2009. The spatial and temporal variations ...
