Abstract

Penelitian perawatan benih ikan gabus (Channa striata) telah dilakukan di Balai Penelitian Perikanan Perairan Umum Mariana, bertujuan untuk mengetahui pengaruh perbedaan padat tebat dan perbedaan volume pakan terhadap sintasan dan pertumbuhan benih ikan. Pada percobaan 1 benih ikan gabus umur 10 hari dipelihara dalam akuarium yang berisi 5 liter air dengan perlakuan 3 tingkatan padat tebar yaitu 4, 6, dan 8 3kor/l diberi pakan Moina sedangkan Percobaan 2 benih umur 10 hari dipelihara dalam wadah silinder berisi 10 liter air dengan padat tebar 4 ekor/l diberi pakan masing-masing 1,2 ml, 1,8 ml, 2,4 ml, dan 3,0 ml moina perhari. Hasil penelitian menunjukan perbedaan padat tebar berpengaruh sangat nyata (P<0.01) terhadap sintasan dan berpengaruh nyata (P < 0.05) terhadap pertumbuhan benih ikan gabus. Perbedaan volume pakan tidak menunjukkan pengaruh nyata (P>0.05) terhadap sintasan dan pertumbuhan benih ikan gabus

Abstract

An experiment was conducted in order to evaluate the effect of differentfertilizer regimes on biological productivity and water quality of limed acid sulfatesoils fishponds. The experiment consisted of 4 different fertilizer treatments i.e.,control without fertilizer input, chicken manure 50 g/m2 /week, chicken manure 75 g/m2 /week, and inorganic fertilizer (6 g of urea + 3.5 g of TSP /m /week), eachtreatment with 3 replications. Result of experiment shows that Inorganic fertilizationgave the highest chlorophyll a concentrations (83.40 mg/m3), and the highest net fishyields 7.53 kg /ha /day), but had a lower water pH than that in control. Ponds whichare fertilized with chicken manure 75 g /m2 /week gave the highest fish survival rate(100%) while in ponds without fertilizer inputs only 3.3 % of stocked fish wassurvived.

Abstract

ABSTRACTInvestigation on lethal effect of leaf fowder of Nerium oleander to nile tilapia fingerlings was conducted on May 2011 in Hydrobiology laboratory of Research Instute for inland Fisheries.Static bioasays was carried out using 9 glass aquariums filled with 10 liters of test media and 10 Nile tilapia fingerlings were exposed into each aquarium.The results shows that leaf fowder of Nerium oleander were toxic to fish with 24 h, 48 h and 96h LC50 were 195.39 ppm, 51.22 ppm and 28.70 ppm respectively.Key words: Static bioasays, Nerium oleander, Oreochromis niloticus
