Uzgoj ribe ili ribogojstvo podrazumijeva uzgoj ribe za komercijalnu upotrebu, u spremnicima ili zatvorenim prostorima poput ribnjaka, obi\u010dno za hranu. Ovo je glavni oblik akvakulture, dok se neke druge metode smatraju marikulturom.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Osnova uspje\u0161nog uzgoja ribe definitivno je\u00a0kvaliteta vode<\/strong>. Voda je okru\u017eenje u kojem ribe rastu, \u017eive, di\u0161u i jedu. Na kraju \u0107e zbog svog metabolizma izlu\u010diti otpad u toj vodi. Najve\u0107i otpadni produkt od ribe je\u00a0amonijak<\/strong>\u00a0(NH3) jer je vrlo toksi\u010dan za ribu. Koncentracija od samo 0,02 mg \/ L pokazuje toksi\u010dni aspekt na ribu, ovisno o vrsti. Olakotno je \u0161to se dio amonijaka ionizira u\u00a0amonij<\/strong>\u00a0(NH4 +) kad u\u0111e u vodu.pH<\/strong>\u00a0odre\u0111uje koliko \u0107e amonijak postati ionizirano. Ako se pH smanji, koli\u010dina amonija \u0107e se pove\u0107ati. Amonij je po\u017eeljniji od amonijaka, jer je amonij manje toksi\u010dan za ribu. Posljedi\u010dno, akvakulturisti moraju izmjeriti i pH i razinu amonijaka. To im poma\u017ee utvrditi koliko ostaje kao amonijak i koliko je ioniziranog u manje \u0161tetni amonij. Ukupnu razinu amonijaka u vodi spremnika treba odr\u017eavati ispod 3 ppm. Kori\u0161tenje\u00a0mikroorganizama<\/strong>\u00a0koji metaboliziraju amonijak u nitrate mo\u017ee smanjiti razinu amonijaka. Taj je postupak poznat pod nazivomnitrifikacija.<\/strong><\/p>\n

Amonij i amonijak mogu se izmjeriti\u00a0Nesslerovom metodom<\/strong>\u00a0u kojoj reagensi reagiraju s amonijakom i amonijem stvaraju\u0107i \u017euto sme\u0111i spoj. Ako je koncentracija amonijaka i amonija ve\u0107a, intenzitet boje bit \u0107e ve\u0107i. Fotometri se mogu koristiti za mjerenje intenziteta boje jer ljudske o\u010di ne mogu otkriti suptilne promjene boje.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Otopljeni kisik<\/strong>\u00a0odnosi se na razinu slobodnog, nevezanog kisika prisutnog u vodi ili drugim teku\u0107inama. Ovaj nam parametar govori o kvaliteti vode zbog utjecaja na organizme koji \u017eive u vodenom mediju. Nepovezani kisik ili slobodni kisik (O2) je kisik koji nije vezan ni za jedan drugi element. Prisutnost slobodnih molekula O2 u vodi zapravo je otopljeni kisik. Ako su molekule kisika povezane u vodi (H2O), to se ne ubraja u razinu otopljenog kisika.<\/p>\n

Razina otopljenog kisika (DO) jedan je od najkriti\u010dnijih parametara u kvaliteti vode i uzgoju ribe. DO se ugra\u0111uje u vodu iz atmosferskog zraka i fotosintezu iz fitoplanktona. Da biste imali zdrave ribe, potrebna je razina zasi\u0107enja od 60 do 70% kisika. Ako su razine DO niske, to \u0107e utjecati na ribe i njihov rast. Ribe koje djeluju letargi\u010dno i vi\u0161e su na povr\u0161ini vode, suo\u010davaju se s problemom nedostatka kisika. Ponekad izgube apetit i to utje\u010de na njihov rast. Ve\u0107e ribe trebaju vi\u0161e kisika i ako nema dovoljno kisika, prije \u0107e razviti simptome. Jer sav taj otopljeni kisik treba svakodnevno mjeriti.<\/p>\n

Ako \u017eelite u potpunosti nadograditi svoju proizvodnju, mo\u017eemo projektirati sustav kontrole za va\u0161e ribogojili\u0161te koje se bavi intenzivnom ribogojnom kulturom. Sustav automatizacije koristi se za pra\u0107enje i kontrolu parametara okoli\u0161a (poput pH, D.O., temperature), hranjenja ribe, prozra\u010divanja. Nudi lak\u0161i pristup odr\u017eavanju, posebno na polju planiranih zadataka koje svakodnevno obavlja tehni\u010dko osoblje. Pru\u017ea kontinuirano pra\u0107enje D.O. razine i mogu\u0107nost postavki alarma. Oprema za upravljanje i nadzor DO \u010desto se koristi zajedno s aeratorima, na taj na\u010din minimiziraju\u0107i drift DO i prekid rada u ribnjaku.<\/p>\n

Na sadr\u017eaj kisika u vodi jezerca mo\u017ee se utjecati dvijema metodama; promjenom brzine protoka i prozra\u010divanjem vode u ribnjaku<\/em><\/strong>.<\/em><\/strong><\/p>\n

Ovo je jedan od na\u010dina na koji se ribogojili\u0161te mo\u017ee optimizirati kako bi se pove\u0107ala njegova ekonomska dobit.<\/p>\n

Sva se na\u0161a oprema mo\u017ee povezati putem interneta, \u0161to korisnicima daje komociju daljinskog povezivanja.<\/p>\n
