Peches experimentales des crustaces profonds dans les eaux de la martinique ( pandalidae, nephropidae ). Prospections, rendements et biologie des especes.

TL;DRAbstract

The principal objective of the work carried out in the deep waters adjoining the island shelf around Martinique between July 1991 and april 1992 was to establish an initial inventory of potentially exploitable deep benthic resources.The cylindrical lobster pot used during fishing experiments allowed the catch of a varied carcinological marine organisms of which six species at least have economic interest : 5 species of shrimp all belonging to the sub-order of Caridea of the Pandalidae family : Plesionika edwardsi, P. (macropoda) polyacanthomerus, P.laevis, Heterocarpus ensifer and H.laevigatus, and one species of prawn of the Nephropidae family : Eunephrops cadenasi. The yields, compared to those of commercial fishermen, were medium or good for Plesionika edwardsi and P. (macropoda) polyacanthomerus between depths of 200 - 300 metres ; for Plesionika laevis and Eunephrops cadenasi in the vicinity 500 metres ; for Heterocarpus laevigatus below 700 metres. The species Heterocarpus ensife
