“…All the culture structures were designed following silvofisheries techniques such that the function of mangroves as nursery grounds for commercially exploited finfish and crustaceans were not hampered (Trino and Rodriguez, 2002). Four replicate rectangular pens of size 6 m x 2 m were enclosed with 'uzio' (sticks tied together to form a mat) as used by local fishermen to trap fish in mangrove channels and other intertidal areas.…”

“…The crabs inhabit mangrove forests and are fished commercially throughout the Indo-Pacific. Mud crabs are sought as quality food for local village consumption and for sale in tourist hotels, where they fetch high prices due to their excellent taste, texture and nutritive value (Cowan, 1984;Trino and Rodriguez, 2002).…”

“…Such alternatives can be achieved through small scale mud crab aquaculture in the WIO region. These small scale and low investment grow-out crab farms are located within natural mangrove habitats and designed to produce high yields of crabs while maintaining the integrity of the mangrove ecosystem as nursery and feeding grounds for fish (Trino & Rodriguez 2002).…”

“…Mud crabs are successfully cultured in Southeast Asia using wild seed stock for grow-out, where survival is between 30% and 85% based on stocking density and feed under pen (200 m 2 ) culture systems (Trino and Rodriguez, 2002). The survival variations have been associated with the cannibalistic nature of S. serrata and change in habitat conditions.…”

Abstract-A study was conducted in Mtwapa creek on the north coast Kenya, during 2005Kenya, during -2007 to evaluate the viability of pens and drive-in cages for mud crab (S. serrata) culture as a mangrove management strategy and alternative source of income for local communities. Other objectives were to assess the effectiveness of drive-in cage construction materials (fito and bamboo) in improving mud crab culture and influences return on investment. The applicability of morphomentric equations in estimating growth was also tested. Four replicate pens (6 m x 2 m) were stocked with 2 crabs/m 2 while individual drive-in cages (30 cm x 30 cm x 30 cm) were joined to form ten in one group (1 replicate) and a total of four replicates used. Uniform feeding was applied for all crabs in pens and drive-in cages using a mixture of fish offal and gastropod meat once a day at 10% body weight. Specific growth rate and survival of mud crabs were evaluated together with the cost of investment for the three months culture period. Drive-in cages recorded a significantly better survival and growth rate (53.2 ± 12.78%; 1.25 ± 0.42 g/day) compared to pens (31.25 ± 2.95%; 0.68 ± 0.24 g/day) p < 0.05 while no significant difference was observed between drive-in cages made of different materials (fito and bamboo). A link between growth rate and size of crab was observed, where growth rate decreased with increasing weight. Moulting associated factors contributed highly (45%) to the total mud crab mortality recorded (p < 0.05); mortality also had a strong positive relationship with moulting (R 2 = 0.79, p > 0.05). Strong relationships existed in morphomentric equations between carapace length and weight (W = 0.0006L 2.9941; R 2 = 0.86, p > 0.05). The construction costs for pens were three times more than those for a similar number of drive-in cages. Cost-return analysis on a per year basis/50 crabs showed that the use of either bamboo or fito as cage construction material was economically viable with a return on capital investment of 122.3 -181.7%. Therefore the integration of mud crab culture in mangrove forest is feasible in Kenya.

“…Kepiting bakau ini memiliki potensi besar untuk dibudidaya di kawasan Asia-Pasifik (Trino & Rodriguez, 2002). Namun demikian, saat ini produksi kepiting bakau di Indonesia masih didominasi oleh hasil tangkapan dari alam karena kegiatan budidayanya belum berkembang dengan baik.…”

ABSTRAKSalah satu upaya untuk menekan tingkat kanibalisme dan memicu pertumbuhan krablet kepiting bakau adalah dengan pemberian pakan yang cukup, baik jumlah maupun mutu. Penelitian ini bertujuan mengevaluasi kinerja pertumbuhan dan sintasan krablet kepiting bakau dengan frekuensi pemberian pakan berbeda pada stadia pendederan. Hewan uji berupa krablet kepiting bakau dengan bobot awal 0,037 ± 0,005 g dan lebar karapas awal 3,43 ± 0,42 mm; menggunakan sembilan unit fiber gelas dengan ukuran masing-masing 1 m x 1 m x 0,5 m. Hewan uji ditebar dengan kepadatan 50 ekor/m 2 . Perlakuan yang diujicobakan adalah frekuensi pemberian pakan per hari, yaitu: (A) dua kali (pukul 08.00 dan 18.00), (B) tiga kali (pukul 08.00, 13.00, dan 18.00), dan (C) empat kali (pukul 08.00, 13.00, 18.00, dan 23.00). Pakan yang digunakan berupa pelet dengan kandungan protein kasar 46,5%; lemak 8,8%; dan energi total 18,8 MJ/kg. Dosis pakan harian sebanyak 30%-15% bobot badan secara menurun hingga akhir penelitian. Setelah lima minggu pemeliharaan didapatkan hasil yang menunjukkan bahwa pertumbuhan, sintasan, konsumsi pakan harian, rasio konversi pakan, dan rasio efisiensi protein tidak menunjukkan perbedaan yang nyata (P>0,05) di antara perlakuan. Namun demikian, pemberian pakan empat kali sehari cenderung menunjukkan pertumbuhan yang lebih cepat dan dengan ukuran krablet yang lebih seragam.
