Abstract

Hatchery and culture technology of Humpback grouper has been developed. However,  sometimes it is still found constraint in sedd production and caused instability of production due to failure by many factors. Breeding program become necessary to provide seed with high quality and good genetic variation. Quantitative characteristic selection is one of breeding program to improve productivity in grouper aquaculture. The aim of this research was to produce good phenotyphic and genotypic quality of Humpback grouper candidate broodstock. Selection of Humpback grouper F1 and F3 was done based on quantitative characteristic (body length and weight) and genotyphic characteristic by using ramdom amplified polymorphism DNA (RAPD) method.  The results of conventional selection were found candidate broodstock of Humpback grouper F1 and F3 with body weight range from 170-210 g and 160-170 g consecutively.  Heterozygosity values of Humpback grouper analized by RAPD of F1 and F3 were 0.7940 and 0.7749 consecutively and it was not significantly different. This value emphasis that population of this F3 Humpback grouper was still good to grow for broodstock. Keywords: genetic variation, humpback grouper, F1, F3.

Abstract

Leopard coral grouper, Plectropomus leopardus is one of the most economically important finfish fish in Indonesia and the demand for the grouper is rapidly increasing in Asia and the Pacific. Grouper exports from Bali were 1,613 mt in 2001, 2,082 mt in 2002 and 2,861 mt in 2003. Understanding the reproductive biology of fishes is an important component in developing mariculture and in the management of capture fisheries. This study reports on the reproductive biology of 86 coral groupers collected from various locations in Indonesia. The length and weight of these fish were recorded and related to gonad development. There was a strong relationship between length and weight; weight being proportional to the length raised to the power (b value) 3.2. As the value of b was greater than 3, this suggests that growth is allometric. Histological analysis 73% of the fish were immature, 19% were in transition from females to males, only 4% were male, and only 2 fish (2%) had mature gonads: these were female. The sex of 2 fish could not be determined. From these data it can be seen that the leopard coralgrouper has asynchronous gonad development. The two fish that were mature contained 343,980 and 429,259 oocytes and three distinct sizes of oocytes could be found. This suggests that the grouper is a multiple spawner. If fish are required for brood stock, this study has shown that only those with a length greater than 35 cm in standard length should be taken from the wild.

Abstract

Gondol Research Institute for Mariculture identification of tuna and rainbow runner was an objective in this current study. Samples of five species were collected from territorial water of North Bali. The method used in this study was allozyme electrophoresis. The results showed that buffer of CAPM-6 (citric acid aminoprophylmorpholine) resulted in a sharp and clear banding pattern. The species could be differentiated in six diagnostic isozyme patterns Idh* (isocitrate dehydrogenase), 6Pgd* (6 phosphogluconate dehydrogenase), Gpi* (glucose phosphate isomerase), Mdh* (malate dehydrogenase), Est* (esterase), and Sp* (sarcoplasmic protein). All species were in Hardy-weinberg equilibrium. Heterozygosities of species were ranged from 0.00 to 0.099. Yellowfin tuna has the highest heterozigosity compared with the other species. Clustering samples according to pairs revealed that genetic distance of Bullet tuna (A. rochei) and Eastern little tuna (E. affinis) had small value (0.001). By contrast, the largest value was observed between yellowfin tuna, T. albacares and rainbow runner, E. bipunnulata (0.007). This value indicated that Bullet tuna (A. rochei) and Eastern little tuna (E. affinis) closed relation, while among yellowfin tuna, skipjack tuna, and rainbow runner, were separated phylogenically.

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

Humpback grouper (Cromileptes altivelis) has been successfully spawned in 2000 by IMRAD (Institute of Mariculture Research and Development) and there are already the third generation (F3) currently. The reproductive aspects need to be studied to support the success of seed production. Humpback grouper reared in floating cage (F1 and F3) had matured (gonad stage 4) while F2 fish reared in concrete tanks has spawned. Gonadal maturity stage of 38 fishes from first generation (F1) and 35 fishes from the third generation were observed in June 2013 and compared to gonadal maturity stage of 18 fishes from the second generation observed in June 2009. Samples were measured in total length and body weight and gonads were taken for histology preparation to determine gonadal maturity stage and the sex. From the histological observation of the gonads, it showed that all female humpback grouper were in early maturity stage (stage I and II) with gonadal maturity index between 0.12% and 5.45%. Further, it was observed that the same gonad was found in different maturity stage and concluded that humpback groupers were multiple spawners (asynchronous). By determining gonadal maturity level, it was also known the minimum size for grouper ready to spawn.

Abstract

Upaya pengembangan perbenihan teripang pasir bagi kelestarian populasi di alam dan pengembangan budidaya patut dilakukan. Upaya ini diperlukan mengingat semakin intensifnya penangkapan teripang di alam yang dapat menimbulkan terganggunya kelestarian populasi ini. Tujuan dari penelitian ini adalah untuk mengevaluasi performa pertumbuhan benih teripang pasir, mendapatkan informasi keragaman genetik dan mengestimasi laju inbreeding dari 3 sumber induk teripang yang berbeda. Tiga sumber induk berasal dari perairan Bali, Sulawesi Selatan, dan Maluku Tenggara masing-masing sebanyak 20 ekor dianalisis menggunakan mikrosatelit (SSR/Simple Sequence Repeats) dengan 3 lokus, yaitu Hsc-28; Hsc-49 dan Hsc-59. Proses pembenihan mengikuti pedoman teknis yang sudah ada dengan beberapa modifikasi. Hasil yang diperoleh menunjukkan bahwa panjang dan bobot benih umur 6 bulan yang dihasilkan dari induk Maluku Tenggara relatif lebih tinggi (5,67 ± 0,76 cm; 13,26 ± 5,63 g) dibandingkan dengan benih dari induk Sulawesi Selatan (4,75 ± 0,91 cm; 6,3 ± 2,22 g) dan Bali (4,85 ± 0,64 cm; 6,2 ± 3,6 g). Hasil analisis mikrosatelit menunjukkan bahwa keragaman genetik induk teripang pasir dari ke tiga populasi tidak berbeda nyata. Hal ini berdasarkan nilai differensiasi genetik (FST= 0,2475 atau 24,75%). Laju nilai inbreeding dalam populasi induk teripang pasir cukup tinggi (FIT= 0,4237 atau 42,37%) dibandingkan dengan laju inbreeding antar populasi (FIS) adalah 0,2342 atau 23,42%. The effort of sea cucumber seed production for culture development have to be carried out. This effort is also required due to the intensive exploration of sea cucumber in the nature which could threaten of its sustainability. The aims of this research is to evaluate sea cucumber juveniles growth performance, to obtain the information on genetic variation, and to estimate the rate of inbreeding from three different sea cucumber broodstock sources. Three sources of sea cucumber were collected from Bali, South Sulawesi, and Southeast Moluccas. The total of 20 pcs from each area were analyzed by microsatellite (SSR Simple Squence Repeat) with 3 locus namely Hsc-28; Hsc-49 dan Hsc-59. Hatchery production of sea cucumber seed followed the existing manual with some modifications. Result of the experiment showed that the length and weight of 6 months old juveniles produced by Southeast Moluccas’s broodstock were relatively higher (5.67 ± 0.76 cm; 13.26 ± 5.63 g) compared to the juveniles produced by South Sulawesi’s broodstock (4.75 ± 0.91 cm; 6.30 ± 2.22 g) and Bali’s broodstock ( 4.85 ± 0.64 cm; 6.2 ± 3.6 g). Results of microsatellite analysis showed that genetic variation of the three broodstock populations was not significant different. It is based on the genetic differentiation value (FST= 0.2475 or 24.75%. The result of inbreeding rate within the broodstock of sea cucumber population was high (FIT= 0.4237 or 42.37%) compare to the rate value of inter population (FIS= 0.2342 or 23.42%.
