Common carp (Cyprinus carpio) germplasm were sourced from Bauchi and Ibadan aimed at studying their hatchability from the various intraspecific crosses and effect of frequencies of feeding on stocking density of Carp fry. Both male and female were injected with Ovaprim at 0.5ml/kg body weight intramuscularly at a single dose. The number of eggs in 1 gram mass was determined, Fertilization rate and percentage of hatchability were calculated. One hundred and eighty (180) fry of Cyprinus carpio were randomly picked and distributed in nine bowls of 50 litres at three stocking densities with replicates for each treatment. The frequencies of feeding were in these order; Ten (10) fry per bowl of 50 litres were fed twice a day, Twenty ( 20) fry per bowl of 50 litres were fed four times a day, Thirty (30) fry per bowl of 50 litres were fed six times a day, respectively for 8 weeks with 30gm of 0.2mm Coppens starter diet. The Ib♀ x Ba♂ cross had the highest hatchability though highest fertilization rate was recorded by Ba♀ X Ba♂ cross. The various crosses had above 50% hatchability, though percentagehatchability differed significantly at (P <0.05). While the growth pattern of the different stocking densities at different feeding frequencies differed significantly (p<0.05). The intra specific crossing of different sexes from the two sources gave a higher yield as can be seen with the IB♀ x BA♂. Whereas carp fry stocked at a lower stocking density with a fewer feeding frequency had best growth.

Carp Cyprinus Carpio

The objective of this research was to obtain probiotic bacteria isolated from the digestive tract of catfish Clarias batracus, to evaluate its effect on growth performances and survival rate of carp. After purified, the bacteria was identified through biochemical tests and selection was carried out through proteolytic, amylolytic, cellulolytic, tests as well as pathogenicity test. Probiotic candidate was administered orally to fish at different concentrations. The fish were fed for 30 days respectively as much as 3% of body weight per day with feeding frequency of two times a day. The results showed that addition of probiotics into feed significantly increased growth performance but not survival rate.Keywords: Probiotic, Clarias batracus,  growth performance, aquaculture. ABSTRAKTujuan dari penelitian ini adalah untuk mendapatkan bakteri probiotik yang diisolasi dari saluran pencernaan ikan lele Clarias batracus, dan mengevaluasi pengaruhnya terhadap kinerja pertumbuhan dan kelangsungan hidup benih ikan mas. Bakteri probiotik diidentifikasi melalui uji biokimia dan seleksi dilakukan melalui proteolitik, amilolitik, tes selulolitik dan patogenisitas. Kandidat probiotik diberikan pada ikan secara oral dengan konsentrasi berbeda Pemberian pakan berprobiotik berlangsung selama 30 hari sebanyak  3% dari berat badan per hari dengan frekuensi pemberian dua kali sehari. Hasil penelitian menunjukkan bahwa penambahan probiotik ke dalam pakan secara signifikan meningkatkan kinerja pertumbuhan namun tidak memengaruhi kelangsungan hidup benih ikan mas.Kata kunci : Probiotik, Clarias batracus, kinerja pertumbuhan, budidaya
