Abstract

The natural stock of sea cucumber Holothuria scabra (known as sandfish) has been declining in both population and size, making it difficult to collect broodstock and juvenile sandfishes for aquaculture. This research aims to evaluate the reproduction of domesticated broodstock (F-1) and performance of the juveniles (F-2). Broodstock were reared in two rectangular concrete tanks with a dimension of 190 x 290 x 70 cm3. There were 12 individuals (7 males and 5 females) of broodstock (F-1) with total length and mean body weight of 12.0 ± 1.21 cm and 122.6 ± 32.37 g, respectively. Six broodstock were put in each tank and fed with compressed benthos at 4% biomass daily in the afternoon. During our experiment, domesticated sandfish broodstock successfully spawned twice. The first spawning (occurred in January 2017) had one female spawned that released 1,350,000 eggs with a hatching rate of 57.4%. Another broodstock spawned in April 2017 and produced 3,280,000 eggs with a hatching rate of 78.66%. The growth performance of 170 days-old juveniles (F-2) shows a total length of 5.66 ± 0.90 cm and a mean body weight of 10.08 ± 2.07 g. The survival rates are 5.19% and 8.68% for juveniles spawned in January and April, respectively. We conclude by showing that sandfish could be domesticated to produce seeds for further aquaculture development.

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

Pertumbuhan dan sintasan larva dan benih kerapu sunu turunan ketiga (F-3) dari induk turunan kedua (F-2) hasil seleksi telah diamati di Balai Penelitian dan Pengembangan Budidaya Laut, Gondol. Induk F-2 diseleksi menggunakan marka indikator tumbuh cepat PL-03 (alel tunggal berukuran 370 bp). Penelitian ini bertujuan untuk mengevaluasi keragaan pertumbuhan dan sintasan larva dan benih kerapu sunu F-3 serta pewarisan sifat tumbuh cepat dari induk kerapu sunu (F-2) kepada benih kerapu sunu F-3. Pembenihan menggunakan induk kerapu sunu F-2 dengan sifat tumbuh cepat (membawa marka PL-03) dan tanpa sifat tumbuh cepat. Telur dan larva yang dihasilkan dipelihara sebagai turunan F-3 hingga berukuran benih dan dibesarkan selama 10 bulan pemeliharaan. Hasil pengamatan sintasan larva kerapu sunu F-3 dari induk membawa marka PL-03 adalah sebesar 10,6% ± 9,1%; sedangkan larva F-3 dari induk yang tidak membawa sifat tumbuh cepat hanya sebesar 2,7% ± 1,7%. Benih F-3 dari induk membawa marka PL-03 dapat dipanen saat mencapai ukuran 2,5-3,0 cm pada umur 38 ± 2 hari, sedangkan benih F-3 dari induk tanpa marka PL-03 pada umur 40 ± 1 hari. Selanjutnya benih kerapu sunu F-3 dari induk yang mempunyai marka PL-03 yang dipelihara selama 10 bulan memiliki laju pertumbuhan harian lebih baik (3,11%) dibandingkan benih kerapu sunu F-3 tanpa marka PL-03 (3,01%). Sintasan benih kerapu sunu F-3 dengan marka PL-03 tidak berbeda nyata dengan yang tidak mempunyai marka PL-03. Persentase benih F-3 turunan dari induk F-2 dengan sifat tumbuh cepat yang membawa marka PL-03 sebesar 45%.The growth and survival rate of the third generation (F-3) of coral trout grouper larvae and fry from the genetically selected broodstock were observed at the Institute for Mariculture Research and Development, Gondol. The F-2 broodstock were selected using the fast-growing marker indicator, PL-03 (single allele of 370 bp in size). The aim of this study was to determine the growth performance and survival rate of larvae and fry of F-3 coral trout groupers, as well as inheritance of fast growth trait from the F-2 broodstock to the F-3. The eggs and larvae of F-3 produced from F-2 broodstock with fast growth trait (having PL-03 marker) and without fast growth trait were reared to reach fry stage for 10 months. The results showed that the survival rate of the F-3 larvae from broodstock with PL-03 marker was 10.6% ± 9.1%, while F-3 larvae from the broodstock without fast growth trait only reached 2.7% ± 1.7%. Fry (F-3) with PL-03 marker reached the optimum harvest size of 2.5-3.0 cm at 38 ± 2 days old, while the F-3 fry of broodstock without PL-03 marker took relatively longer to reach that size (40 ± 1 days age). The F-3 from the broodstock with PL-03 marker reared for 10 months had better growth rate (3.11%) compared to F-3 fry without PL-03 marker (3.01%). The survival rate of F-3 fry with PL-03 marker was not significantly different to F-3 fry without PL-03 marker. The percentage of F-3 fry from the broodstock of F-2 with fast growth trait was 45%.
