4.5.6.7.8.9.10.11.F12.13.14.What is the relationship between production in the water column and sea bottom?Is the present knowledge of fish migration and/or movement in the region sufficient toexplain the spatial separation between the areas of highest primary production and theareas of greatest importance to the fisheries? What aare the distribution and abundanceof different stocks?What are the water chemistry parameters in the reef crevices in which many of the smallfish live?How do unusual weather conditions affect reef organisms?What ecological processes allow more species to co-exist in some parts of the Red Seathan in other parts?Are important resources (such as food and habitat) more finely partitioned?Do physical and/or biological disturbances (i.e. predation) keep species populationsreduced in size?To what distance from their hatching places into the open sea do the larvae of nearshorefish travel?The annual changes in biomass and composition of the ichthyoplankton.How is the diversity of the reef fish community is established and maintained?To what extent &e there adequate qualifiid manpower resources to design andimplement the wide variety and number of science projects in the region?To answer the above mentioned questions there is great need to identify the high priorityresearch tools which can be expected to be needed for projects in biological and physical oceanographyin the Red Sea. These include:1. Well-equipped laboratories close to coral reefs; they should be designed for long-termcontinuous operation over a time frame of decades rather than years.2. To build a cohesive data base to make information readily available to all workers andmanagers.3. Reef conservation programme and a strategy for reef management.As our ability to intervene in physical and chemical processes that renew certain resources canaffect natural systems at very large scales and at relatively rapid rates,* W e should try to understand the processes linking the physics with biology.* A determined effort should be made to produce a clear regional inventory of existinginformation on the Red Sea environment, including both fauna and flora with emphasison fisheries as an important item of the living resources.REFERENCESBUDKER, P. and FOURMANOIR, P, (1954).
