Abstract

Animal populations found out on tunny-fishing coco-fibres nets in Camogli, have been taken into consideration to value their composition in relation to the depth and to the variations supervened during the period of spring-summer 1979. Besides, the contribute that these populations give to the richness of the tunny-fishing nets has been valued. A characteristic seasonal course with conspicuous variations for nematode worms and hydroids (the first reach the maximum number of presence in June, the second both in June and July) has been verified. In conformity with the depth, the most evident variations concenr the hydroids, with prevalent presence in surface in May and June and in the depth in the following two months.
