Abstract

 Lionhead strain goldfish (Carassius auratus) inheritance produce many variations in phenotype qualitative traits of their offspring that is not common with the parents. Lionhead is an ornamental freshwater fish, they do not have a dorsal fin, but it is a beauty finfish, is popular to the people and have a high economic value. Of the 846 offspring of lionhead is produced in this experiment, and 57,7% of them have dorsal fin (42,3% normal), 13,1% of them have anal fin which did not similar with their parents, 58,6% caudal fin of them did not have similar to their parents. It might be caused by incompletely segregation in meiosis and many gen responsible to certain phenotype trait. Another abnormalities such as no anal fin, blindness, stumped and no pigmen in their gill lamella also occurred. Key words: Inheritance, fin, phenotype, abnormality   ABSTRAK Ikan maskoki strain lionhead menghasilkan keturunan dengan fenotip yang sangat bervariasi dan berbeda dengan induknya. Ikan ini merupakan ikan hias air tawar yang tidak memiliki sirip punggung namun tetap memiliki keindahan, sehingga menjadi begitu populer di masyarakat dan memiliki nilai ekonomi yang tinggi. Sebanyak 846 keturunan (anakan) telah dihasilkan dalam percobaan ini, dan sebanyak 57,7% dari populasi tersebut memiliki sirip punggung (berarti 42,3% merupakan keturunan normal), 13,1% memiliki sirip dubur yang tidak mirip dengan induknya. Variasi keturunan ikan maskoki strain lionhead ini disebabkan oleh segregasi yang tidak sempurna dalam proses meiosis dan banyaknya gen yang terlibat dalam pembentukan penotip tertentu. Abnormalitas lainnya juga terjadi pada keturunan ikan maskoki strain lionhead ini, seperti tidak adanya sirip dubur, mata buta, tubuh pendek dan tidak adanya pigmen pada lemela insang Kata kunci: Keturunan, sirip, fenotip, abnormalitas

Abstract

The experiment was conducted to study the effect of thyroxine hormone injection on female marble goby on metamorphosis and survival rate of their larva. Thyroxine hormone was injected into female at the dosage of 0,25 and 50 µg/g body weight. And then the female were reared with males in spawning tanks. Spawned eggs were hatched and the larva was observed for organogenesis, yolk absorption and growth in length. Formation of eye spot, swim bladder and body pigment becoming faster as the increase in thyroxine hormone dose. Yolk volume in larva that was obtained form thyroxine injected female decreased faster than those of control. Thyroxine hormone did not affected length growth and survival rate Key words: Marble goby, broodstock, thyroxine, metamorphosis, survival rate, larva

Abstract

The experiment was carried out to study the effect of embryo immersion in estradiol-17β hormone solution on sex ratio, hatching rate and survival rate of betta fish. Eyed embryo were immersed in 400 µg/I estradiol-17β for 0 (control), 6, 12, 18 and 24 hours, and then the larva were reared until reaching three month old. Immersion in estradiol-17β hormone increased percentage in female, and the highest value was achieved at 12 hours of immersion. Increasing treatment duration to 24 hours decreased the survival rate of betta fish. The lowest value of hatching rate was found at 24 hours of immersion. Key words: Feminization, betta fish, betta splendens, sex ratio, survival rate and hatching rate

Abstract

The objective of this research was to study the effect of LHRHa gonad maturity in broodstock of P. hypophthalmus through W/O/W LG (C-14) emulsion injection. The treatments consisted of control (A), 50 µg/kg fish wight (B), and 100 µg/kg fish weight (C), with five replications of each. Fish weight at the beginning of experiment was 2.0 kg/individual. The result showed that LHRHa in W/O/W emulsion had positive effect on egg maturation. This was shown by the value of average of eggs diameter. The maximum size of egg diameter for fish 701.52 ± 17.56 µm. The size of eggs was more homogenous in group B than those of group C and A. it was concluded that injection of LHRHa in W/O/W LG (C-14) emulsion if effective in promoting gonad maturation and oocyte development in the catfish

Abstract

Rifampicin-resistant marker was employed as a reporter to assay pathogenicity of Vibrio harveyi  in shrimp larvae.  V. harveyi M. G3 and G7 that difference not schizotyping as shown by Pulsed-Filed Gel Electrophoresis (PFGE) used in this study. Spontaneous mutation was conducted to generate V. harveyi resistant to rifampicin. Two groups of shrimp post-larvae (PL5) were immersed for 30 min in 106 CFU/ml of mutants and wild type of V. harveyi, respectively; and then placed in a 2 liter shrimp rearing tank for five days. A control group was immersed in sterile seawater. Growth curve analysis and pathogenicity assay of V. harveyi  showed that each of the V. harveyi mutant exhibited almost identical profiles to that of the wild type parental strain and did not show alteration in their pathogenicity. Sample from dead shrimp larvae showed that the dead shrimp larvae were infected by V. harveyi RfR, indicated that rifampicin-resistant marker effective as a reporter to assay pathogenicity of Vibrio harveyi in shrimp larvae. Key words: shrimp larvae, Vibrio harveyi, rifampicin-resistant, molecular marker

Abstract

Dip treatment on pearl oysters (Pinctada maxima) was conducted in different concentrations of saline water to eliminate boring polychaetes. Results shows that polychaetes leave the oysters which treated on saline water at 0 ppt, 45 ppt, and 60 ppt as long as 15 minutes each. It also shows that the oysters got high survival rate 7 days after the treatment. Key words: Pearl oyster, Pinctada maxima, polychaetes, salt, dipping, survival rate

Abstract

The experiment was done to find out species, intensity and prevalence of common crap fry from traditional ponds and "longyam" at Sukamulya village, Singaparna, Tasikmalaya. This experiment was conducted at Sukamulya village and Aquatic Biology Laboratory of Fisheries Department, Faculty of Agriculture, Padjajaran University form October 1st 2002 to October 31th 2002. Samples of common carp fry were obtained from six traditional ponds and six "longyam". The survey method was used in this experiment of common carp fry at difference type of pond were based on the Wilcoxon rank sum test. Intensity and prevalence of ectoparasites of common carp fry at traditional ponds and longyam was based on the Kruskal-Wallis test.

Abstract

This experiment was carried out in the framework of a project to develop a viable shrimp polyculture technology under intensive farming. The objectives were to assess the effect of adding white legged shrimp (Penaeus vannamei) on growth and survival of tiger shrimp (Penaeus monodon) in intensive Farming. Tiger shrimp were stocked in 2800-3400 m2 earthen ponds at 40 individuals/m2 and reared for 133 days. White legged shrimp added at 70 day at 8±2 individuals/m2. Growth rate and total yield affected by addition of this species. Final  affected by white legged shrimp addition. No adding effects were found on the water quality parameters. The results indicate that, at densities tested, white legged shrimp addition to the intensive farming of tiger shrimp polyculture is viable as species increase crop production Key words: Penaeus vannamei, P. monodon, growth, survival, polyculture
