Abstract - This research to seeing the effect of bread yeast (Saccharomyces cereviciae) in improving the respons non-specific immunity in tilapia (Oreochromis niloticus). Tilapia with an average weight of 31.83 g is maintain in five aquariums with a density of 5 tails per aquarium. Fish fed with pellets mixed with breat yeast in accordance with the treatment of treatment A (control), treatment B (10 g / kg pellet), treatment C (20 g / kg pellet), treatment D (30 g / kg pellet) and treatment E (40 g / kg of pellets). Feed is given in accordance to the dose of 5% with the frequency of feeding 2 times a day ie Morning and Afternoon. The result of ANOVA show that giving bread yeast into pellet feed as much as 10 g had an effect on total leucocytes, phagocytosis activity and absolute growth.

Abstract

Abtract - This research aims to prevent, the effect of pomegranate extract in the treatment of Cantang grouper and the concentration of pomegranate extract which is appropriate to the survival rate of Cantang (Epinephelus sp) infected by V. alginolitycus. The method of this research is laboratory experiment using three treatments and each treatment is done by three replications, 5%, 10% and 15% of pomegranate extract concentration is done in BBIP Tablolong, Kupang Barat subdistrict, Kupang regency. The indicator used to determine the effectiveness of pomegranate extract is by measuring the haemotology and morphology of fish while the indicator to see the exact concentration of extract is to see the test fish synthesis. The results showed that giving of pomegranate extract had an effect on V. alginolitycus and treatment with concentration of extract 10% showed higher survival than other treatment.

Abstract

Abstract - This research has been conducted to determine the effect of different culture techniques (net pen culture techniques, racking techniques and raft techniques) on the growth and sulvival Atactodea striata (Polymesoda erosa) culture in the intertidal area. This research was conducted from April until June 2017, in Laterite village, Kupang Subdistrict. The experimental design used in this study was Randomized Block Design (RAK). Anova's results show that different culture techniques have a significant effect on the growth and length of Atactodea striata (Polymesoda erosa), where the net pen culture techniques get better length and weight compared to rack and raft techniques. The average length of growth in net pen culture technique (0.63 cm), rack technique (0.53 cm), and raft technique (0.37cm) where Fcount (8.17) > Ftable (5.14) (7,51 grams) and raft technique (6,54 gram) where Fcount (74,56) > Ftable (5, 5,54 gram) 14) at a significant level of 5%. Although different culture techniques have a marked effect on growth, it is not significantly different from the life of the Atactodea striata.

Abstract - Pumpkin seeds contain lots of vitamin E so it can be used as a supplement for the brood fish to improve the maturities gonad. This study used a pumpkin-seed flour added in to the feed (pellets) which aims to determine the index maturity of gonad (IMG) 0f lele sangkuriang (Clarias sp.), and the concentration of pumpkin-seed flour is effective against gonad maturity. The study was conducted for 2 months using completely randomized design (CRD) with the treatment of pumpkin seed concentration in the feed ie: 0, 100, 150 and 200 gram /kg of feed each treatment was repeated 3 times. The results shows that the highest IKG value was 5.7 (± 0.55) in treatment with 200 g / kg of feed compared with controls whose IGM value was only 2.6 (± 0.39), while treatment with 100 and 150 g / kg of feed obtained by IMG value 4,21 (± 0,89) and 44,98 (± 0,48). The data analysis, ANOVA, showed that the treatment hight significant (P˂ 0.01) on IMG.The study condution concluded that the addition of pumpkin-seed flour into the feed can increase the maturity of the gonad of lele sangkuriang. Keywords : Pumpkin Seeds, IKG, Catfish.

Abstract - The study has been conducted in Batubao,west region of Kupang, for 3 mounths, to know the rates of E. cottonii growing and carragenan content by second pitch of seaweed reding. The second pitch seeds were the newtreatent that thalus was pitched out from two times 25 days cultivation of F2_seed. The rates of growing and carragenan production of F2_seed was companing to 45 days cultivation of sea weed, a conventional seed called control seed. Both of seed eas cultivated subseguently for 45 days. The results shows that the biomas of F2_seed treatment raise to 636±23,30 g and control are 617±23,97 g. The carragenan protection of F2_seed are 7,2% and control are 6,4%. The corelysion is growing and carragenan production of F2_seed treatment are higher them the conventional seed. Keyword : Seaweed, Eucheuma cottonii, Growth, Carrageenan.
