Ribnjačarstvo Riba“ d.d. Kaniška Iva se nalazilo na području Bjelovarsko-bilogorske županije a svom je začetku bilo u vlasništvu Agrokombinata Zagreb. Površinske veličine 531 ha i podjeljeno na 13 ribnjaka. Uz standardizaciju svakodnevnih poslova na ribnjačarstvu, cilj upravljanja proizvodnjom je smanjiti rizike ekonomskih gubitaka, nepoželjnog utjecaja na okoliš, pojavu i širenje bolesti te rizike vezane uz zaštitu zdravlja ljudi. Proizvodnja mlađa na ribnjačarstvu se zasnivao na ličinkama iz vlastitog umjetnog mrijesta. Mrijest, inkubacija ikre i ličinka provodio se u mrijestilištu za umjetni mrijest toplovodnih vrsta riba. Prije tehnološkog procesa uzgoja jednomjesečnog mlađa toplovodnih vrsta riba moraju biti dovršene hidrotehničke pripreme tla tj. obrada dna i nasipa ribnjaka. Dno ribnjaka mora posjedovati lagani pad prema odvodnom kanalu odnosno ispustu ribnjaka. Uzgoj ribe na ribnjačarstvu provodio se u dvogodišnjem i trogodišnjem sistemu do konzumne veličine. Zbog sve manjih prinosa te lošijih rezultata kod nasada i uzgoja, u razdoblju od 2013. – 2017. godine, ribnjačarstvo se dovodi do stečaja.

"Riba" d.d., a fish farm from Kaniška Iva was located in the area of Bjelovar-Bilogora County and previously was owned by Agrokombinat Zagreb. It was divided into thirteen fish ponds with a surface area of 531 acres. With the standardization of daily tasks on the pond, the purpose of production management is to reduce the risks of economic loses, adverse impact on the environment, the emergence and spread of the disease and risks related to the protection of human health. The production of fry on the pond is based on larvae from the artificial spawning. Hatching, spawning and larvae incubation was carried out in artificial hatcheries for warmwater fish. Before the conduction of technological process of farming a one-month-old warmwater fry species, hydro-technical soil preparation ie. treatment of the pond bottom and the embankment must precede. The bottom of the pond must be with a slight drop to the drainage channel. Fish farming was carried out in a two-year and three-year system up to the point when the fish can be consumed. From 2013 to 2017 fish farming was brought to bankruptcy, due to the low income and bad farming results.
