Sažetak
The data on the production and catch of fish according to sorts, pond ackerage, fishing means as well as the distribution of production and catch in 1995 have been stated in the paper. Ackerages used for the fish production have been increased by 1710 acres or 6.51%; total fish prinos* is less for 1,252 tons or 17.05%. The highest production of fish was reched by the fish farm Donji Miholjac with 859 kg/ha.
A nutritive coefficient is 3.0 kg and it is less by 3.22% compared with the previous year. The nutritive coefficient is less than 2.0 kg in three fish-farms but it is greater than 4.0 kg in five large fish farms. Mostly corn but also wheat dominate in fish nutrition.
The fertilizers consumption has been reduced by 14.53%.
Of total pond ackerage, growing fish farms occupy 1.25%, new fish farms occupy 17.90% and consumptive fish farms occupy 79.64%.
Total fish production in carp ponds is 507 kg/ha and 136.1 ton/ha in trout ponds.
With 84.33%, carp is the mostly produced fish sorts, herbivore fish follow it with 3.89% and the production of all other fish makes 11.78% of the total.
With 83.97%, grass carp takes the first place in the structure of herbivore fish. It is followed by the big head carp with 9.28% and silver carp with 6.75%.
The trout production has been slightly increased by 6. 3%. Pike has appeared again and all other fish sorts has been reduced.
Fish catch in open water has been increased by 7.06% compared with the previous year.
When we sum up total production and catch of fresh-water fish, we can conclude that carp contributes with 81.08%; herbivore fish with 3.67%; trouts with 5.53%; sheat-fish, pike-perch and pike with 2.74% and all other fish sorts with 6.98%.
As to the distribution of production and catch, there has been 49.02% sold on markets, 38.02% has been spent on farm reproduction (set back in ponds), the percentage of mortalities is 7.90%. Sport fishers have spent 5.06% of fish.
The number of employees has been reduced by 12.05% and fish production per employee has also been reduced by 1.10% compared with the previous year.
It has been produced 8.0 tons of fish per employee. In 1995, the production has been greatest in Draganići: 15.60 tons of fish per employee.
