This paper deals with the design and application of different fishing gears tested in the Beagle Channel (Tierra del Fuego, Argentina) with the supervision of the technical personnel of INIDEP Fishing Gear Group, the support of the General Directorate of Natural Resources (known today as SRNyAH) of Tierra del Fuego, Antártida e Islas del Atlántico Sur Province and the participation of local fishermen. Activities started as a result of an agreement between the INIDEP and the SRNyAH ratified in 1994. The fishing gear tested, which consist of two paired midwater trawl nets, a gill net, a surrounding net, a bottom lingline, a pot for kingklip and a line of octopus traps may be used in vessels ranging from 30 to 120 HP in coastal waters, channels and inland... |

This work reports on the inter rod distance in a single sorting grid adapted for the escape of hake juveniles. A good performance of the device was reported due to the DEJUPA trials carried out in April 1997. In may 1998 a new survey with DEJUPA was carrie out with 30 mm, 33 mm, and 40 mm separation distance bars, in order to optimise the escape of the species at first length maturity (35 cm). Selectivity curves with maximum likelihood method were obtained for each inter rod distance being the length at 50. (L50) 29, 32 and 37 respectively. A weighd lineal regression (Feasible General Squares Model) between L50 and inter rod distance was fitted from each L50 estimated variance. An estimation of 37 mm inter rod distance for L50=35 cm total length was... |

This Technical Manual has been developed to frame, assemble and apply the single grid sorting device (DEJUPA). It is addressed to professionals, technicians in fishing gears, skippers, owners and fishermen. The Manual presents three DEJUPA sizes in function of the main engine power: less than 300 HP, between 300 and 800 HP and more than 800 HP. |
