Abstract

This paper discusses the current status of tilapia aquaculture production, historical development based on the production growth, technological advances in genetic improvement and culture system, trade and product development, strategies, and policies in maintaining and improving national production. All data and information used in this manuscript were collected from available publications relating to the past and present status of tilapia cultivation in the country. Nowadays, Indonesia is the second-largest tilapia producer in the world with the contribution of about 25.89% to tilapia global production. In Indonesia, tilapia is the largest production among other cultured species. The annual growth production of tilapia is inccread 11.61% from 2011 to 2018. West Java Provinceis the largest tilapia producer followed by West Sumatra, South Sumatra, and Central Java. In the last six years, most of tilapia production comes from pond culture followed by floating cages, net cages, paddy fields, and pen culture. The success of tilapia culture is much influenced by technological improve in grow-out and genetic improvement of the local varieties. A side of that, trading and global market oriented are also established with various acceptable products. Tilapia aquaculture in Indonesia shows the succsess story of freshwater aquaculture program from nothing before 1990 to be something at present time. To maintain and increase the future production of tilapia, it needs strategies and policies in production and trade. The tilapia program maybe used as a role model for another economic imprortant freshwater species in Indonesia.

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

Mahseer (Tor spp.) is a freshwater fish commodity with a high market value. However, its slow growth to reach consumable size has resulted in inadequate production. The aim of this study is to analyze the hybrid vigor - that are heterosis, heterobeltiosis, and growth performance - of a crossbred population of Mahseer (Tor spp) resulting from interspecies breeding. Broodstock of Mahseer from three different species were prepared for reciprocal breeding, producing nine offspring populations consisting of six hybrid offspring and three purebred offspring populations. The breeding process was carried out using artificial breeding methods, employing intramuscularly injected breeding stimulant hormones. Results show that the hybrid population of Tor soro and Tor tambroides exhibits better heterosis and heterobeltiosis in final weight, specific growth rate, and survival rate. The crossbreeding of Tor soro and Tor tambroides also exhibited better growth performance compared to other crossbred population in terms of final weight growth, specific growth rate, and survival rates, which were 64.20 g, 1.42%/day,  and 100% respectively.
