The Sub-Program of Benthic Crustacean Fisheries and the Development of Fishing Gear, Capture Methods and Technology Transfer Program of the National Institute for Fisheries Research and Development (INIDEP) are carrying out in in Necochea and Quequén a survey of experimental fishing for rowing crab (Ovalipes trimaculatus) and comparison of different trap designs.
INIDEP technicians making tests with traps
In the Willie and Bernie coastal vessels, different test hauls will be carried out for five days to determine the distribution and relative abundance of the rowing crab in the fishing areas near Puerto Necochea.
In addition, the relative efficiency of different trap designs for the crab capture will be evaluated and their operational management will be optimized (anchoring times, distance between traps, mesh sizes). The reproductive status and population structure of the fraction accessible to fishing gear will also be characterized.
Different types of traps tested
The experience is carried out in consecutive departures, according to the climatic conditions and boats availability. Two scientists/technicians will embark by boat and work will be carried out in the area between latitudes 38º 50 'S and 38º 70' S and from the coast to 35 meters depth (three miles).

In particular, this survey will test a wicker trap design carried out by Manuel Agliano together with personnel from the Fishing Gear Development Program, Capture Methods and Technology Transfer.
The results obtained in these experiences will allow to advise many artisanal fishermen who come to the Institute to learn about this resource´s potential.
