Tech­no­log­i­cal Ap­proach to Aqua­cul­ture

Uzbekistan Today (English) - - REGIONS -

In the Bukhara re­gion, 240 fish farms and other en­ti­ties are en­gaged in fish farm­ing, at whose dis­posal ar­ti­fi­cial reser­voirs with an area of 1.6 thou­sand hectares. One of the lead­ing places among them is the Bukhoro Ba­lik Sanoat lim­ited li­a­bil­ity com­pany.

The en­ter­prise was cre­ated through equity par­tic­i­pa­tion and a loan from the re­gional branch of Ipoteka Bank, as well as from the ini­tia­tors of the pro­ject in the amount of 7 bil­lion soums. Its spe­cial­ists have or­ga­nized an ar­ti­fi­cial pond with an area of 70 hectares, next to it a pro­duc­tion com­plex has been built, equipped with mod­ern tech­no­log­i­cal equip­ment. Here is an in­ten­sive gar­den in an area of 5 hectares. All the pro­cesses as­so­ci­ated with grow­ing fish are a sin­gle tech­no­log­i­cal chain.

“Breed­ing plays an im­por­tant role in fish farm­ing,” says Davron Niy­ozov, sci­en­tific con­sul­tant at the Bukhoro Ba­lik Sanoat. “This is­sue is of spe­cial im­por­tance to us. 60 mil­lion fry are grown in the in­cu­ba­tion shop. The slight­est inat­ten­tion can lead to their death. There­fore, un­der strict su­per­vi­sion, care work is taken to main­tain a con­stant room tem­per­a­ture.”

Af­ter the in­cu­ba­tion shop, the young are raised in small pools in a closed build­ing un­til the weight of the fry reaches 1.5-2 grams, then in four open pools of 1 hectare they pass ‘sum­mer fat­ten­ing’. When their weight reaches 35-50 grams, they are placed in a spe­cial pool for the win­ter. In spring they are released into large wa­ter, and in au­tumn the fish is ready for har­vest­ing.

A no­table fea­ture of the com­plex is the pres­ence in it of a closed sys­tem of wa­ter cir­cu­la­tion. The com­pany also op­er­ates work­shops for clean­ing, short-term frost and long-term re­frig­er­a­tion stor­age of fish. The store holds 200 tons of prod­ucts. Smoked fish is also es­tab­lished here. As a re­sult, the prod­ucts are de­liv­ered to the mar­ket in frozen and ready-made form.

Nat­u­rally, the pro­duc­tiv­ity of fish grown in an ar­ti­fi­cial pond de­pends largely on the feed. The plant has a pro­duc­tion ca­pac­ity of more than 2 thou­sand tons of feed per year. Here it con­sists of corn, pro­tein, var­i­ous vi­ta­mins and sup­ple­ments. In ad­di­tion, waste from fish clean­ing is re­cy­cled, from which a se­condary food is ob­tained.

“Spring is an im­por­tant sea­son for fish­er­men,” says Kayum Salo­mov, head of the Bukhoro Ba­lik Sanoat LLC. “In small pools, we will start grow­ing white fern, sil­ver carp, African cat­fish. Ac­cord­ing to the plan, in the au­tumn we will catch about 300 tons of fish. Next year, this fig­ure will be even higher. In early Fe­bru­ary, I vis­ited the city of Hanoi at the in­vi­ta­tion of guests from Viet­nam who vis­ited Bukhara last au­tumn. Agree­ments on es­tab­lish­ing part­ner­ships have been reached. In the fu­ture, we plan to cre­ate a joint ven­ture.”

In to­tal, fish farm­ing is es­tab­lished in 8 nat­u­ral lakes and one reser­voir with a to­tal area of 56 thou­sand hectares. This year it is planned to get 8.6 thou­sand tons of prod­ucts, which is twice as much as last year. An im­por­tant fac­tor in achiev­ing this goal is the sup­port for fish farms by the state.
