“…Kapasitas produksi crablet masih belum stabil karena kesulitan memperoleh induk yang berkualitas, saat kunjungan dilakukan pada tahun 2021, produksi crablet baru 20.000 ekor jauh lebih rendah dari tahun sebelumnya. Padahal menurut Yi et al (2009), skala produksi yang direkomendasikan untuk pembenihan kepiting bakau pertama kali adalah sekitar 100.000 crablet.…”

Nilai ekspor kepiting Indonesia turun drastis mulai tahun 2015, sedikit mengalami peningkatan di tahun 2019 namun masih jauh dibandingkan nilai ekspor tahun 2013 dan 2014. Komoditas kepiting Indonesia memiliki daya saing yang kuat di pasar ekspor ditunjukan dengan nilai RCA (Revealed Comparative Advantage) diatas satu. Data tahun 2019 menunjukkan Indonesia baru menyumbang 1,66% dari total nilai ekspor kepiting dunia. Volume produksi kepiting dari tahun 2015-2017 masih didominasi oleh tangkapan alam sekitar 75-85% sedangkan produksi dari budidaya hanya 15-25%. Dari produksi kepiting budidaya 15-25% tersebut benihnya masih bergantung dari alam. Produksi kepiting Indonesia masih bergantung pada hasil tangkapan alam, sementara pemanfaatan sumber daya kepiting terbatas. Tujuan kajian ini adalah untuk memberikan gambaran kondisi saat ini budidaya kepiting bakau dan merumuskan strategi pengembangan budidaya kepiting yang belum berkembang secara optimal. Metode yang digunakan dalam penelitian ini adalah melalui study literatur, wawancara dan Focus Group Disscussion (FGD) yang dianalisis secara deskriptif. Permasalahan budidaya kepiting saat ini adalah benih sulit didapatkan pada bulan-bulan tertentu sehingga kegiatan budidaya terganggu. Mengingat pasar yang masih terbuka luas, namun hasil tangkapan mulai berkurang ditandai sulitnya memperoleh benih kepiting dari alam secara kontinyu, maka kegiatan budidaya dari pembenihan harus segera diwujudkan dan ditingkatkan produksinya. Kebutuhan benih untuk kegiatan budidaya sangat besar sehingga diperlukan banyak hatchery.The export value of Indonesian crabs fell drastically starting in 2015, with a slight increase in 2019 but still far from the export values of 2013 and 2014. Indonesian crab commodities have strong competitiveness in the export market as indicated by the RCA (Revealed Comparative Advantage) value above one. Data for 2019 showed Indonesia only contributed 1.66% of the total world crab export value. The volume of crab production from 2015-2017 is still dominated by natural catch, around 75-85%, while production from aquaculture is 15-25%. Of the production of cultivated crabs, 15-25% still depend on natural seeds. Indonesia's crab production still relies on natural catches, while the utilization of crab resources is limited. This study aims to provide an overview of the current condition of mud crab culture and formulate a strategy for developing crab culture that has not developed optimally. The method used in this research is through literature study, interviews and Focus Group Discussion (FGD), which were analyzed descriptively. The problem with crab cultivation today is that seeds are challenging to obtain in certain months, so cultivation activities are disrupted. The market is still wide open, but the catch is starting to decrease, marked by the difficulty of continuously obtaining crab seeds from nature. The cultivation activities from hatcheries must be realized, and production must increase. Seeds for cultivation activities are huge, so many hatcheries are needed.

“…The pond-based crab culture system totally relies on wild-caught seed (Keenan, 1999), which has become limited by over-exploitation and diminishing mangrove habitats (Le Vay et al, 2001). Although mud crab seed production has been studied extensively (Brick, 1974;Heasman and Fielder, 1983;Marichamy, 1996;Quinitio et al, 1999;Mann et al, 1999;Davis, 2003;Nghia et al, 2007;Yi et al, 2009;Noorbaiduri and Ikhwanuddin, 2015), the survival of hatchery-produced crablets is still unreliable and inconsistent (Baylon and Failaman, 1999;Hamasaki et al, 2011), mainly due to mass mortality during the zoeal (Z) and megalopa stages, especially during metamorphosis from Z5 to megalopa (Hamasaki et al, 2002). Mass mortalities are mainly linked to poor larval nutrition (Hamasaki et al, 2002;Suprayudi et al, 2004) caused by selection of improper feeding regimes.…”

The present larval nutrition study was conducted to evaluate the effects of feeding probiotic-enriched rotifers inclusion mixed with Artemia until zoeal stages 4 (Z4) and Z5 on the survival, metamorphosis, development time and growth of mud crabs, Scylla paramamosain larvae. The efficiency of the feeding regime was tested by two-factor analysis. A 4×2 factorial experimental design with eight combinations of enriched or un-enriched or a mixture of enriched and un-enriched live food (factor 1) in each of two feeding regimes (factor 2) in triplicate was setup. After 24 days of larval cultivation, there were no significant (p>0.05) interactive effects between the two selected factors on survival and metamorphosis rate of larvae. Larval survival in all treatments, under both factors, decreased gradually (p<0.05) during the cultivation period. From 15 Days After Hatching (DAH), the survival and metamorphosis rates of larvae fed both enriched rotifers and Artemia were higher (p<0.05) than those of the larvae without enriched live food. Similarly, from 18 DAH onwards, the extension of rotifers inclusion mixed with Artemia until Z5, irrespective of enrichment, showed higher (p<0.05) survival, metamorphosis and growth of megalopa than when the rotifers were included only until Z4 stage. Overall, an amalgamation of extending rotifer feeding and enriching them at the same time with Artemia can result in considerable improvements in survival and metamorphosis which can in turn, have beneficial impact on the technical feasibility of a commercial crab hatchery.
