Abstract:
ABSTRACT Reproductive design for gonadal maturation process mostly related with some factors such as environmental signals, reproductive organs, hormonal and nutrition. This research was conducted on female Mutiara strain of North African Catfish, Clarias gariepinus by combining two kinds of materials administered to broodstock diet, namely oocyte developer (Oodev) which contains of PMSG hormone and antidopamin, and astaxanthin carotenoid. Research designs were divided into C (Control), A50 (astaxanthin 50 mg/kg feed), A100 (astaxanthin 100 mg/kg feed), Od0.5 (Oodev 0.5 mL/kg fish for two week

Abstract:
The study was carried out for six (6) weeks at the Department of Fisheries Teaching and Research farm, Modibbo Adama University, Yola, to compare the reproductive performance of Clarias gariepinus using synthetic (ovaprim) and natural (C. gariepinus pituitary extract) hormones . At the end of the feeding trial, the fecundity, percentage fertilization, hatchability, and survival rates of the hatchlings were estimated using standard procedure. The hatchlings were further raised for six weeks and the increase in weight was determined. The results showed that female broodstock injected with C. gar

Peningkatan konsumsi ikan air tawar di Kota Kupang menstimulasi para pembudidaya ikan untuk berlomba-lomba meningkatkan produksi usahanya. Mengingat cara budidaya ikan yang dilakukan di Kota Kupang adalah dengan padat tebar tinggi dan tanpa pergantian air, maka dapat menyebabkan kualitas media air menjadi buruk karena adanya dekomposisi dari hasil sisa pakan sehingga memungkinkan perkembangbiakan mikroba patogen. Penelitian ini bertujuan untuk mengetahui gambaran histopatologi pada organ insang, hati dan usus ikan lele di Kota Kupang. Ikan lele sebanyak 100 ekor yang diambil dari Pasar Oeba ke

Abstract:
The study was conducted to evaluate reciprocal hybridizations in the African catfishes Clarias gariepinus and Clarias jaensis using artificial reproduction under controlled hatchery conditions. The results revealed that the highest fertilization (82.77%) and hatching (67.77%) rates were achieved in the hybrid cross female C. jaensis × male C. gariepinus (Fcj × Mcg). Deformed larvae rates ranged from 9.01 to 16.33%; the hybrid Fcj × Mcg recorded the lowest rate. Survival rates in the larval stage were higher than 80% whatever crossing considered. However, it was higher in the hybrid Fcj × Mcg u

Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L). Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus).
