Abstract

Histamine toxicity can be occurred after consumsing decomposing fish (pindang). The community (fishermen) perform different handling techniques on raw materials of pindang to slow down the decomposition process. This research is aimed to know the influence of various techniques of handling fish on the quality of raw materials of pindang. This research used completely randomized design with single factor. This study compared various methods of fish handling commonly used by community (fisherman in Kusamba village) to maintain the quality of raw materials of pindang, such as: kept on room temperature (technique A), add 1 kilogram crushed ice for 4 kilogram fishes (technique B), add 10% salt (technique C), and combination of technique B and C (ice and fish combination 1:8 plus 5% salt as technique D). Diversity analysis show a significant influence of different techniques of fish handling on the quality of raw material of pindang (p value <0.05). Addition of crushed ice show the best quality result among fish handling technique with histamine levels 11.30 mgN%, moisture content 74.53%, TVB 20.19 mgN%, salt 0.32%, bacteria 13 x 101 colonies / g, and negative coliform. Organoleptic assessment for B techniques also show the best result with visibility score 8.0 (bright, strong, and thin scale), eye 7.7 (convex, slightly foggy cornea, slightly faint pupil), odor 7.8 (soft odor), and texture 7.8 (elastic).

Abstract

The objective of this research was to know the survival and growth of post-larvae of several giant gouramy (Osphronemus goramy) subspecies. Experiment in this study used Completely Randomized Design (CRD). The treatment consisted of three strains of giant gouramy, bastar, bluesafir, and bule. Giant gouramy post-larvae were reared for 45 days. The results showed that there were no significantly different among those subspesies of giant gouramy (P>0,05) on survival rate (bastar=86,5%; bluesafir=61,5%; bule=87,0%), weight and length (bastar=0.946 g, 2.975 cm; bluesafir=0.585 g, 2.860 cm; bule=0.826 g, 3.280 cm), also on the specific growth rate of length (bastar=3,070%/day, bluesafir=2,891%/day, bule=3,308%/day). However there was significantly different on specific growth rate of weight (P<0,05) (bastar=7,356%/day, bluesafir=9,464%/day; bule=11,167%/day).

Abstract

Fish naturally has a non-specific defense against several pathogens. The non-specific defense is anatomical and physiological function that varies according to genetical and environmental factor. The differences of non-specific defense against Aeromonas hydrophila infection were studied in blackfinpacu (Colossoma macropomum), gourami (Osphronemus goramy), common crap (Cyprinus carpio), African catfish (Clarias gariepinus), and red nile tilapia (Orochromis sp.). This study also examined the differences on several parameters of non-specific defense, including differentiation anc number of leucocytes, serum total, titer of antibody, and antibacterial activity of skin mucus.The fishes were intramuscularly infected at the media lethal doses for common carp (7,4 x 108cfu/fish). Pathological changes, survival rate, and mean time to death were observed every day. The observation of non-specific defense parameters were carried out prior and at seven day after infection.The results showed thahblackfinpacu was the most resistant species against A. hydrophila infection. African catfish and red nile tilapia were most resistant than gourami and common carp. The antibody titer and percentage of thrombocytes were the causative factor for the difference of the resistence against A. hydrophila. The five fish species also showed differences on leucocytes number, monocytes and eosinophiles percentage, and serum total, but they did not showed the differences of neutrophile percentage. The skin mucus of all fish species did not exhibited antibacterial activity against A. hydrophila. This study also found increase in antibody titer and leucocytes number after A. hydrophila infection.

Abstract

Five isolates of A. hydrophila were used for MIC, and resistency test to rifampicin, kanamycin, chloramphenicol, erythromycin and oxytetracyclin by dilution method with TSB medium. The results indicated that the bacteria had various degree of sensitivity to these antibiotics. Resistency of bacteria isolates increase 1.3 to 6.2 times after they were passaged three times to MIC of the drugs or antibiotics by dilution method. Other test was kanamycin medication conducted by i.p. injection, immersion, and oral methods. The result showed that all kanamycin medication methods were effective to decrease mortality rate caused by A. hydrophilia infection. Oral medication method was the most effective compare to other methods because this method could minimize stress during handling. However, oral medication took much longer time (15 days) than immersion and injection methods (few minutes).

Abstract

The purpose of this research was to identify the reproductive biology in the yellow rasbora (Rasbora lateristriata) in habitat of the Ngrancah River. To identify spawning events and embryo development, direct observation was employed during the spawning season in their natural environment, and then fertilized egg was incubated insitu. Spawning seasons underwent correspond to the end of rainy season and early dry season which characterized by clean freshly water and low temperature. The result showed that during spawning season, the broodfish migrated from Sermo Reservoir upward to the main river to find out the spawning site. In the early morning between 03.00 and 05.00 AM, the broodstock moved to the spawning site, then making aggregation and both female and male released their gametes in the shallower place. The aggregations were consisting around of 1 female and 3 males. The fertilized eggs would cleavage, and then embryo developed and yolk sac larval hatched within 23 hours at 27oC. The knowledge about spawning events of yellow rasbora may be used for improved management tools in the future.

Abstract

This research aims to know antioxidant activity, total phenolic, nutrient, and screening phytochemistry compounds of S. hystrix dry powder. Water extract from the dried sample of brown algae (S. hystrix) was prepared and examined for its phenolic compounds. The amount of total phenolic compounds in water extract was about 11.43 g Gallic Acid Equivalent (GAE)/100 g of dry basis sample, as measured by using Folin-Ciocalteu method. The antioxidant activity (Radical Scavenging Activity/RSA) of BHT as a standard was high about 96% inhibition of radical DPPH with 1 mg dry sample/ml solvent. The IC50 of the BHT was 0.227 ± 0.001 mg of dry sample/ ml solvent. While the radical activity (RSA) of S. hystrix dry powder was about 65.28% at 1 mg dry sample/ml solvent. The IC50 of S. hystrix dry powder was 0.616 ± 0.005 mg of dry sample/ml solvent. Nutrient contents and bioactive compounds of dry powder S. hystrix were balanced to support antioxidant activity of the sample. The results suggest that this alga is a potential source of natural antioxidant.

Abstract

This study was conducted to investigate the effect of dietary L-carnitine level on muscular lipid and body composition of asian catfish (Pangasius hypopthalmus). Four isoprotein and isocaloric diets with different levels of L-carnitine, 0.00% (diet K), 0.10% (diet A), 0.18% (diet B), and 0.29% (diet C) were applied in this experiment. Ten fishes with initial body weight of 35.86 ± 1.54 g were cultivated in each aquarium (water volume 60 l) for 50 days. Fishes were fed three times daily at satiation. The results showed that L-carnitine in the liver increased by increasing dietary L-carnitine level. While increasing dietary L-carnitine until 0.18% decreased content of lipid in the liver, but excessive dose of dietary L-carnitine increased content of lipid in the liver. It was further observed that L-carnitine in the diets reduced the muscular lipid content from 32.35 to 7.51% dry weight, but had no effect on body composition.
