Abstract

Shrimp breeding research focusing on fast growth traits is important to develop better phenotypic and genotypic characters of shrimp spawners. The aim of this research was to evaluate shrimp breeding technology to produce fry having fast growth traits. Selection was initiated from the breeding of wild shrimp spawners (F-0) based on full sib mating, probiotics, biosecurity, and viral diseases diagnosis. Viral disease diagnoses were performed using 7 viruses (TSV, WSSV, IHHNV, YHV, BP, MBV, and HPV) provided in the IQ-2000 kit. The result showed that 11 families of the first generation (F-1) shrimp were phenotypically varied (big, regular and small size). Number of fry from the first generation resulted from phenotypic selection that have fast growth trait ranged between 1.99% and 4.49% of the total fry population. Genotypic performance of the shrimp broodstock (F-0) and the first generation (F-1) showed different genetic variations. Heterozigosity values were 0.2872±0.0047 (female) and 0.5487±0.0103 (male) for shrimp broodstock (F-0), 0.704±0.0261 for the first generation (F-1) having fast growth trait, and 0.6224±0.023 for F-1 having slow growth. Gene markers of fast growth trait were indicated by the genes with molecular weights of 1,025; 1,280; and 1,325 basepairs and having different DNA sequences compared to that of slow growth shrimp.

Abstract

In order to improve immune system of Pacific white shrimp L. vannamei from any kinds of diseases, various probiotic agents were tested such as Bacillus sp. BC, Alteromonas sp. BY-9 and mixed of both. The probiotics were cultured and added directly to the larval rearing tank (106 cfu/mL equal to 0.5 liter/m3) up to PL-12. In cultured shrimp spawners, probiotic was mixed with feed coated with chitosan, and without adding probiotic as control. In the present experiment, shrimp fry and spawners were reared in tank capacity of 5 m3 and 8 m3. Immunity response was analyzed by quantitative value of the immunity related gene expression with RTqPCR. The results showed that survival rate of shrimp fry cultured with mixed probiotic was 63.16% (PL-8) and 53.46% (PL-12), while control 13.35% (PL-8) and 12.48% (PL-12) respectively. The number of shrimp hemocytes starting from 420 to 530.5 x 104 cells/mL and after challenged with WSSV (for 72 hrs exposure) between two treatments of Alteromonas sp. BY-9 and Bacillus cereus BC was not significantly different P>0.05 (402.5 and 432.5 x 104 cells/mL), while in mixed probiotic and control treatments were 391.75 and 229.0 x 104 cells/mL, respectively. The analysis of immunity gene expression revealed that the use of probiotic from larval stages up to spawner has been proved in increasing immunity responses quantified from ProPO activating system (prophenoloxidase/proPO) as much as 1.6-2.0 fold, clotting system (transglutaminase, clotting protein) of 1.5-2 fold, Antimicrobial Peptide System (anti-LPS factor, crustin, lysozyme, penaiedin2) of 1.5-2.8 fold, and Antioxidant defense mechanism (superoxidase dismutase/SOD, glutathione peroxidase/GPx) of 1.8-2.0 fold compared to control.

Abstract

Standard method to asses the performance of black tiger shrimp (Penaeus monodon) fry was needed for successful shrimp culture. The main purpose of this study was to determine standard method fry performance of P. monodon assesment based on its morphology and molecular RNA/DNA ratio analysis. Samples of P. monodon fry were collected from hatcheries in Bali, six hatcheries in East Java, three hatcheries in Central Java and six hatcheries in South Sulawesi. Each hatchery gave 25 appropriate sizes of fry samples taken from same tank culture. RNA/DNA ratio value was obtained from gene-quant measurement.  Result of this study shown that morphology performance of shrimp fry correlated with RNA/DNA ratio.  RNA/DNA ratio of shrimp fry from Bali hatcheries were obtained of 0.7121. Shrimp fry from hatcheries in East Java  showed  RNA/DNA value ranged between 0.2823-1.2132, while shrimp fry from hatcheries in Central Java and South Sulawesi  ranged between 1.1810-17478  and  0.1798-0.5116 respectively.

Abstract

Fluctuating asymmetry has been widely used as a measure of developmental stability and as an indicator of individual fish growth. The present study compared fluctuating asymmetry in three bilateral meristic traits of F-1 hybrid between female Epinephelus fuscoguttatus and male Epinephelus polyphekadion and two F-1 pure parental progenies. The fishes were reared by communal and separate tank systems. Hybrids were confirmed by allozymes electrophoresis. After three months of rearing, the F-1 hybrids fish grew faster 45.9% and 66.6% compare to the F-1 pure parental progenies of E. fuscoguttatus and E. polyphekadion (P<005) respectively. Development stability as measured by fluctuating asymmetry was lower in hybrid (20%-40%) than in the pure parental progenies (53%-80%). Among four enzyme loci examined, only Pgm locus showed variants and at that locus all hybrids fish were heterozygous. Heterozygous hybrids showed lower fluctuating asymmetry and related to higher developmental stability. The higher developmental stability positively reflected a faster growth rate. Thus this finding can be used to explain the reason that why hybrids groupers appeared grew faster than parental species.
