Plankton is the basic food of fish in the larval state, and of pelagic and some<br />

other fish in the adult state. Where it is lacking the whole fish population is<br />

affected, because even those fish which do not feed directly on plankton will<br />

feel its loss at one or two removes. The Black Sea, well fed by great rivers such<br />

as the Danube, is comparatively rich in plankton. The <strong>Mediterranean</strong> itself is<br />

poor. The famous blueness of the <strong>Mediterranean</strong> and the clarity of its waters<br />

betray this poverty, and while they attract human beings they signal a marine<br />

desert to fish. The relative poverty of the <strong>Mediterranean</strong>, most severe in the<br />

eastern basin, accounts for the limited population of pelagic fish. The net<br />

effect of the exchange of waters with the Atlantic is not helpful in this respect.<br />

Looking ahead to the future, scientists are wondering whether some artificial<br />

means can be found of creating a greater vertical movement of waters in<br />

the <strong>Mediterranean</strong>, since there are nutrients at depths where they cannot be<br />

utilized. Meanwhile it is unhappily true that the broad trend is for fish supplies<br />

in the <strong>Mediterranean</strong> to diminish, although much valuable work is being<br />

done, often with stimuli and help from the FAO, to offset the disadvantageous<br />

factors, for instance by improving the cultivation of fish in the numerous<br />

brackish lagoons around the <strong>Mediterranean</strong> coast.<br />
