1. Introduction

Survey objectives.

The general objectives for the whole survey programme are described in the report of the planning meeting held in Trinidad, 12 - 14 January, 1988 and summarized in the Preliminary Report of Cruise No I, Part 1.

On basis of the experience from the two previous cruises and discussions with representatives from the participating countries the following clarifications are made for the third survey.


As during the two previous cruises one should give attention to the areas off the mouths of the large rivers and to the snapper grounds at mid-shelf (30-40m bottom depth) and at the shelf edge (80-100m). At mid-shelf day hauls should be carried out to investigate the snapper resources, while night-hauls should aim at shrimp which bury during daylight hours. The pelagic resources are best sampled during night. Tests of the fishing grounds where the fishing fleet is operating should be made in order to assess by catch and catch rates. A request was also received at the onset of the survey to test the deep sea shrimp resources previously reported by a Japanese resource survey.


The previous programme should be continued, with sampling of the inshore and offshore assemblages of finfish and from the fishing grounds of the commercial shrimp trawler fleet.


The programme will basically be a repetition of the previous survey. There is an interest to do more sampling of shrimp resources at mid-shelf during night-hours. Further tests of the deep sea shrimp resources should be made.
