Striped snakehead is one of the potential local species, however, its production in Indonesia still comes from capture fisheries. Over exploitation had decrease the population in nature. Domestication is one of promising tool to solve the problems faced. In order to breed the domesticated species, the information of their reproduction was needed. This study aimed to describe relationship between length and weight, length and fecundity, weight â fecundity and gonad weight â fecundity of the striped snakehead from West Java. A total of 19 mature female specimens were collected from Parung (Bogor), and seven mature female specimens were collected from Babelan (Bekasi). The results showed that the determinant value (R2), the first for Parung and the second for Babelan, between weight and fecundity were 0.599 and 0.843, length-fecundity were 0.541 and 0.841; gonad weight â fecundity 1.00 and 0.846 Gonadosomatic Index (GSI) ranged from 0.67 to 9.94% and 2.03 to 8.17%. Gonad Index ranged from 6.17 â 76.73 and 18.48 â 76.77, respectively. The data indicated that growth pattern was allometric. Length and body weight has linear relationship with gonads and fecundity. Fecundity has higher correlation to the weight rather than length. Gonad weight and fecundity has a strong relationship.

One way to support the increase of aquaculture production is to produce superior strains of growth. Carp as one of the potential for these commodities only rely on local strains which have had a decline in quality. For that, the effort to generate superior growth of carp need to be done. One way to do that is by hybridization. We carried out reciprocal crosses of 4 strains of carp Rajadanu, Subang, Majalaya and Kuningan to obtain 16 new strain candidates. Furthermore, growth test was conducted to find out the best candidate of the absolute and specific growth parameters. From these results, it was concluded that the absolute growth in length, weight, and the highest biomass obtained by crosses of SB x RD, the highest length and weight Specific Growth Rate obtained by crosses of RD x MJ. For the highest degree of survival is at the intersection of KN x SB, whereas the highest survival rate in the use of female parent KN. In the dominant male of female survival is the parent SB. The biggest positive heterosis character length growth values obtained by crosses of SB x RD. For the highest weight growth heterosis values obtained by crosses of SB x MJ. On the character of hatching, the highest positive heterosis values obtained by crosses of SB x MJ. The degree of survival of the highest heterosis values obtained by crosses of KN x MJ. On the character of the highest positive heterosis values of biomass obtained by crosses of SB x MJ. As for the character length SGR highest positive heterosis values obtained by crossing two directions of RD and SB. And for the character weight Specific Growth Rate, the highest positive heterosis values obtained by crossing two ways KN and MJ.

This study was conducted to examine activity of medaka (Oryzias latipes) â-actin promoter (mBP) in common carp(Cyprinus carpio) as the first step towards development of common carp transgenic in country. Gene constructpmBP-hrGFP that consists of mBA promoter and humanized Renilla reniformis green fluorescent protein gene(hrGFP) was injected into cytoplasm of one cell stage of common carp by using microinjector. PmBP-hrGFPconcentration used for microinjection was 50 μg/mL aquabides. Parameters observed were survival rate of embryo(SRe), hatching rate (HR) and expression of hrGFP gene. SRe was calculated before eggs hacthed, while hatchingrate (HR) was after all of eggs hatched. The activity of mBA promoter was analyzed by observation of hrGFP genetransient expression using a fluorescence microscope. The results of experiment showed that SRe (87,5%) andHR (79.2%) of control was respectevily higher than that of injected treatment (75.0% & 61.7%). Expression of hrGFPwas observed firstly at blastula (12 hours after fertilization) to 1-day-old larval stages (24 hours after hatching)with higher gene expression at blastula to late gastrula stages. Percentage of micronjected larvae expressinghrGFP at 6 hours after hatching reached 71.6 ± 6.7%. Conclusion was that mBA promoter could drove hrGFPexpression in common carp, hence it can be used to produce common carp transgenic by changing hrGFP withgenes correlated with important traits in aquaculture.
