Abstract

Two experiments were conducted in the IRD-Gamet Laboratory, Montpellier, France. The first experiment was to evaluate the recovery of Heterobranchus longifilis females gonad after induced ovulation, under tropical condition.  Eggs diameter was used as indicator of the recovery rate following by induced breeding, hatching rate and abnormality of larvae. The results showed that the recovery was about 28 - 35 days after ovulation. The second experiment was carried out to improve milt production by hormone treatments, volume of intra testicular sperm and the numbers of spermatozoa were observed.  The results indicated that the treatmens did not prove any significant differences. Keywords: hormone, gonad, reproduction, Heterobranchus longifilis   ABSTRAK Dua kegiatan penelitian dilakukan di Laboratorium IRD-Gamet, Montpellier, Perancis.  Penelitian pertama dilakukan untuk mengetahui recovery gonad ikan Heterobranchus longifilis betina setelah ovulasi, di daerah tropis.   Diameter telur digunakan sebagai indikator recovery gonad, diukur pada saat sekitar 28-35 hari setelah ovulasi.  Penelitian kedua dilakukan untuk meningkatkan produksi sperma dengan memberikan perlakuan hormon.  Volume semen dan jumlah spermatozoa dievaluasi.  Hasil penelitian menunjukkan perlakuan tidak memberikan hasil yang signifikan.

Abstract

It is really important, since the possible use of these pangasiid hybrids in aquaculture faces the problem of potential impact on wild population. Therefore, it is urgently needed to provide quick identification tools in the field. This study investigated morphological characters of Pangasius djambal and Pangasianodon hypophthalmus and their hybrids. A detailed morphological analysis using 32 morphometric measurements and five meristic counts was done on the hybridization of P. djambal and P. hypophthalmus. Morphometric analysis and meristic counts showed that the reciprocal hybrids have intermediate characters except for gill raker number in which lower than that of parental species. In general, the hybrids have tendency to be like P. hypophthalmus rather than P. djambal. The only typical character of P. djambal appeared on hybrids is teeth shape, both vomerine and palatine. It is clearly defined that the true hybrids have seven pelvic fin rays.

Abstract

Ikan belanak Mugil cephalus adalah salah satu spesies ikan euryhaline dan merupakan ikan ekonomis penting yang terdistribusi secara luas di dunia. Namun, penelitian tentang pengaruh faktor lingkungan terhadap metabolisme ikan ini masih kurang banyak diteliti meskipun hal tersebut penting untuk mengoptimalkan budidaya. Karena itu, penelitian ini dilakukan untuk mempelajari tingkat oksigen terlarut (DO) letal dan gambaran darah ikan belanak pada kondisi pemeliharaan dengan salinitas berbeda. Dua kelompok penelitian dilakukan untuk mengukur kadar DO letal dan gambaran darah ikan belanak pada kondisi pemeliharaan di air laut (LOS) dan air tawar (LOF). Pengamatan dilakukan menggunakan closed rectangular chamber dan sampel darah. Hasil penelitian menunjukkan bahwa kondisi ikan belanak menjadi tidak stabil pada kondisi oksigen terlarut di bawah 2 mg/L (1.3 mg/L pada LOS, 1.6 mg/L pada LOF). Dalam kondisi oksigen terlarut menjadi 1 mg/L, aktivitas ikan menurun dan mengalami kematian pada konsentrasi 0.3 mg/L. Kedua kelompok penelitian yang diamati tidak berbeda nyata (P>0.05). Parameter darah seperti Ht, Hb, osmolalitas, kortisol, dan glukosa dalam percobaan LOS memiliki nilai yang lebih tinggi dibandingkan dengan LOF. Percobaan menunjukkan bahwa indikator respon stress pada ikan belanak semakin meningkat dengan menurunnya kandungan oksigen dalam air. Kadar kortisol berada pada nilai 90.7 ng/ml di LOS dan 56.4 ng/ml di LOF, sedangkan kadar glukosa berada pada nilai 169.0 ng/ml di LOS dan 71.5 ng/ml di LOF. Dari penelitian ini dapat disimpulkan bahwa kadar oksigen terlarut bagi ikan belanak dianjurkan tidak berada di bawah 2 mg/L pada kondisi pemeliharaan di air laut maupun air tawar untuk menghindari kematian pada ikan.

Abstract

In order to manage genetic resources for aquaculture development of snakehead fishChannastriata(Bloch, 1793), genetic variability of three populations from different geographical areas is needed to be understood. The purpose of this study was to identify the genotype and fenotype of snakehead fish from Jawa, Sumatera and Kalimantan using RAPD and “Truss” morphometric. RAPD method used OPA-02, OPA-04 and OPA-07 primers.While twenty one measurement of truss morphometric was done on the body of fish observed. The results showed that population from Java had higher percentage of polymorphism and heterozygosity than those of Sumatera and Kalimantan, accounted for 83.33% and 0.3655 respectively. Population from Kalimantan and Sumatera had the lowest genetic distance of 0.1170.Meanwhile,the highest genetic distance (0.1908) was observed between population from Kalimantan and Java.Interpopulation relation based on the similarity of truss morphometric population from Sumatera and Kalimantan was 50%. However, those populations had similarity of 24.96% with population from Java. Coefficient variation of morphometric data showed that variation of population from Kalimantan was higher than those of Jawa and Sumatera.

Abstract

Rock bream Oplegnathus fasciatus is one of marine fish species with high commercial value in the region of East Asia. However, studies on the metabolism related to environmental factors for this species is still lacking. This study was therefore aimed to assess the effects of salinity and temperature on oxygen consumption (OC) of rock bream (TL: 26.9±0.6 cm, BW: 477.3±61.9 g) was observed by using respiratory chamber to understand the optimal salinity and temperature for culture of rock bream. Research was conducted in Pukyong National University, Busan, South Korea. Four experimental groups were conducted to measure oxygen consumption (OC) according to salinity (35, 25, 15, and 35?5 psu) and temperature changes (15?20?25oC). The results showed that low salinity exposures tend to decrease OC of rock bream (87.1, 78.3, 66.3, and 58.5 mg O2/kg/h at 35, 25, 15, and 5 psu, respectively). Meanwhile, the oxygen consumption of rock bream increased with increasing water temperatures (35 psu: 64.7, 104.0, and 175.9 mg O2/kg/h at 15, 20, and 25oC, respectively; 25 psu: 45.8, 101.7, and 185.9 mg O2/kg/h at 15, 20, and 25oC, respectively; 15 psu: 29.8, 103.3, and 155.5 mg O2/kg/h at 15, 20, and 25oC, respectively).

Abstract

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.

Abstract

The objectives of the study was to evaluate hybrid performance of sixteen reciprocal cross resulted from three strains (Red NIFI,Nirwana, BEST) and one population (Lido Lake population) of nile tilapi. The study was conducted in experimental floating netcages in Lido Lake. Fish of 25 days old ranged 0,4 ± 0.07 g were used in the experiment. Fish were reared in floating net cages sized 2x1x1 m for each cross with the density of 50 fish/cage for eight weeks (56 days). Feed were given 10% of body weight with frequency three times a day. The results showed that the highest average larvae production was 1216 from Nirwana female crossed with four different male. Growth rate of hybrids were higher than the parents (P < 0.05) and the highest was .ed NIFI x c? BEST (6,440±0,0712% ).The highest survival rate was $ Red Lido x S BEST hybrid (77.0 ±2,78%")). For heterosis, Specific Growth Rate (SGR) was 5.8188% on hybrid between Nirwana and Red Lido. While for survival rate was 15.5888% on Nirwana x BEST hybrid. Crossing between fenotipe of light color background (red) and dark color background (black) showed that red color was dominant to the black one. Pleiotric effect of color gen was detected on the SGR and survival rate.
