An acoustic survey was carried out in the bay of Biscay from May 1st to May 30th on board the French research vessel Thalassa. The objective of PELGAS06 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay. The target species were mainly anchovy and sardine and were considered in a multi-specific context. The results have to be used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame of the Ifremer fisheries ecology program "resources variability"

Heral, Maurice; Woehrling, Daniel; Halgand, Daniel; Lassus, Patrick.
The "Bongo" net is an American plankton net whose use is coming into general use for studies of ichthyoplankton. Its dimensions and its power of filtration make it an efficient device for researching groups with unevenly spaced micro distribution as well as rare species, especially fish eggs and larvae. It is recommended by the ICNAF (Standard Techniques for Pelagic Fish Eggs and Larvae Surveys) and will soon be recommended by the FAO. The ISTPM, for its part, has been using this net for some years in several campaigns conducted by the Thalassa, the Cryos, La Pélagia, the Roselys and the Ichthys (ISTPM 1971, 1975, ALDEBERT 1975, ARBAULT and LACROIX 1975). In 1975, we decided to use this net in some studies in coastal waters that the ISTPM is conducting in...
