Ecological study of gas fields in the northern Adriatic: 12. Ecological features of the benthic community

During the period from 1982 to 1985 and at the beginning of 1986 floristic and faunistic compositions and distributions of benthic communities of southwestern rocky coast of Istra and of deeper mobile bottoms of open waters towards the IVANA field were studied. Benthic flora consisted of 245 species and intraspecific taxa of multicelular algae (Rhodophyta 146 taxa, Phaeophyta 57 taxa, Chlorophyta 42 taxa) and 2 species of seagrasses. Regarding quality and quantity zoobenthic settlements are well developed and cover 299 macrozoobenthic species from nine sistematic groups. The distribution of these settlements at deeper mobile bottoms of the open part is characterized by high total and mean values, but showes considerable variations in relation to the mechanical structure of the sediment at certain parts of the studied area. Ichthyological (groundfish stock) settlements are well developed at mobile bottoms of the wider area of the IVANA and IKA fields which is well confirmed by the rather high total amounths of the quantity of the zoobenthos of 47 50 t, of which the edible part ( fish, crustaceans, shellfish and cephalopoda), total 6680 t and nonedible 41270 t. From the point of view of fisheries and economy the wider area of gas fields, due to the abundancy and variability of edible resources, represents a significant part of the open Adriatic fishing grounds.
