CROATIAN FRESHWATER FISHERIES IN 1996.

U radu su izneseni podaci o proizvodnji i ulovu ribe po vrstama, o površini ribnjaka, o ribolovnim sredstvima i o raspodjeli proizvodnje i ulova u godini 1996. Površine koje se iskorištavaju za proizvodnju ribe smanjene su 1.357 ha ili 11, 99%, a ukupan je prinos ribe manji za 1.921 tonu ili 29,76%. Hranidbeni je koeficijent 4,0 kg veći, u odnosu na prethodnu godinu 33,33%. Potrošak je gnojiva smanjen 18,79%. Od ukupnih površina ribnjaka rastilišta čine 5,99% površine, mladičnjaci 21,13%, a uzgajališta za konzumnu ribu 71,53%. Ukupan je prinos ribe u šaranskim ribnjacima 376 kg ha, a u pastrvskim 146,6 tona ha. Od svih ribljih vrsta najviše se proizvodi šaran 82,21%, zatim pastrva 8,57%, biljožderne ribe 4,78%, a sve ostale ribe čine 4,44% ukupne proizvodnje. U strukturi biljoždernih riba na prvome je mjestu amur s 64,28%, a slijede sivi glavaš s 26,02% te bijeli glavaš s 9,70%. U usporedbi s prethodnom godinom nešto je povećana proizvodnja pastrve i lin jaka, a smanjena je proizvodnja svih ostalih vrsta. Ulov ribe u otvorenim vodama povećan je 19,23% u usporedbi s prethodnom godinom. Zbrojivši ukupnu proizvodnju i ulov slatkovodne ribe, udio je šarana 77,46%, biljoždernih 4,32%, pastrve 7,87%, soma, smuđa i štuke 2,99% i svih ostalih ribljih vrsta 7,36%. Što se tiče raspodjele proizvodnje i ulova, 46,91% prodano je na tržištu, 39,19% potrošeno je za vlastitu reprodukciju (nasad u ribnjake), uginuća iznose 6,23%, a za vlastitu potrošnju (športski ribolovci) potrošeno je 7,67%. Broj ribarskih djelatnika smanjen je 17,75%, a proizvodnja ribe po djelatniku također je smanjena 26,62% u usporedbi s prethodnom godinom. Po djelatniku je prosječno proizvedeno 5,87 tona ribe.Data on the production and fish catch according to species, on the surface of the fish ponds, on the means of fish catching and on the distribution of the production and the catch in 1996 is presented. The surface area used for production of fish has decreased by 1357 ha or 11.99%. The total fish amount has decreased by 1,921.00 tons or 29.76%. The feeding coefficient is 4 kg (33.33%) bigger compared to the previous year. The amount of the fertilizer used has decreased by 18.79%. The fry carp growing ponds make up 5.99% of the total fish pond surfaces, the young carp ponds 21.13%, and the ponds with consumption fish 71.53%. The total fish amount in the carp ponds was 376 kg/ha, and in the trout ponds it was 146.6 tons/ha. The most produced fish species is the carp with 82.21 %, followed by the trout with 8.57%, the herbivorous fish with 4.78%, while all the other fish species make up 4.44% of the entire production. In the structure of herbivorous fish the grass carp is leading with 64,28%, followed by the big head carp with 26.02% and the silver carp with 9.70%. Compared to the previous year the production of the trout and tench has somewhat increased, while the production of all the other species of fish has decreased. Fish catch in open waters has increased by 19.23% in comparison to the previous year. In the production and catch of the total freshwater fish, carp made up 77.46%, the herbivorous fish made up 4.32%, trout 4.32%, sheat fish, pike perch and pike 2.99% and all other fish species 7.36%. As far as the distribution of production and catch is concerned, 46.91% were sold on the market, 39.19% were used for reproduction (stocking the fish farms), mortalities were 6.23%, and for personal use (sports fishing) 7.67% was used. The number of fisheries workers has decreased by 17.75%, and the production per worker has also decreased by 26.62%, compared to the previous year. Average production per worker was 5.87 tons of fish
