Abstract

The aimed of this field practice was to study the hatchery technique of freshwater lobster at Board of Freshwater Aquaculture, Tatelu (BBAT). During this practice, all the hatchery activities were conducted according to BBAT standar procedures. The number of broodstocks used in this practice was 225 females and 53 males. These broodstocks were propagated in mating pond for two weeks. Broodstocks having eggs were moved into hatching tank individually. Afterward, broodstock was removed into another tank while larvae were kept in hatching tank for 10 days. Larvae were cultivated in concrete tank for one month. Data collected included surviral rate, weight and length of lobster, and water quality. Survival rate of larvae was 50%. Water quality in broodstock tank was temperature 28,4 0C, pH 7,5; DO 5,6 mg/l, in hatching pond was temperature 27,23 0C, pH 7,5; DO 5,2 mg/l. In general, lobster hatchery consisted of tank preparation, boroodstock culture, broodstock seletion, hatching, larvae rearing, feeding, water quality contol, pest and disease prevention, harvest. Key Words: Hatchery, lobster, broodstocks.

Abstract

ABSTRACT This research aimed to determine the proper dose of white onion (Allium sativum) powder to stimulate the nonspecific immune response and growth of carp (Cyprinus carpio L). Fish (length 8-12 cm; weight 9.37 g in average) were obtained from BBAT Tatelu (Freshwater Aquaculture Board). After acclimatized in 1000-l fibre tank for two weeks, fish were introduced to 15 glass aquaria (80x40x40 cm) equiped with aeration at a density of 15 fish/aquarium. Fish were fed diet supplemented with white onion powder at five different doses (0, 10, 20, 30 and 40 g/kg diet), twice daily at 5%bw. Data collected included total leucocyte count (TLC), phagocytosis activity and growth of fish. Results showed that after four weeks of feeding, supplementation of white onion powder at 30 g/kg diet was effective to enhance nonspecific immune response and growth of carp. Keywords: Allium sativum, immune response, total leucocyte count, phagocytosis activity
