“…Statistical analysis indicated that better growth rate was observed in Chicken intestine compared with tilapia and apple snail meat. This result is similar to the findings of Rodriguez et al (2003).The boxes that were used was collected from collection of the farmer. However, he made these boxes by creating holes in color boxes.…”

The present study was conducted to identify low cost feed for female mud crab (Scylla olivacea) fattening practice in plastic box and the effect of different feeds on growth and survival rate of mud crab. A number of 30 adult non-gravid female crabs were reared into rectangular shaped plastic boxes, each box containing one crab. Three types of feed such as Chicken intestine, Tilapia and Apple Snail meat were supplied as feed at 10% of body weight of the crabs once daily considered as Treatment-1, Treatment-2 and Treatment-3 respectively with 10 replications each to compare the fattening system.. The crabs in plastic boxes were floating into water to fatten for 10 days. Survival rate of crab was found 100%, 90% and 100% respectively in chicken intestine, tilapia and apple snail meat. In the experiment food conversion ratio (FCR) and specific growth rate in weight (SGRw) were varied significantly among different foods (P >0.05). Comparative benefit-cost analysis showed that use of chicken intestine as feed in crab fattening attained higher net profit than crab fattening used tilapia and apple snail s feed from 7-12 days fattening period The present study revealed that utilization of chicken intestine as feed for mud crab fattening might be better than any other feeds and cost effective in Bangladesh.

“…D'Abramo, Daniels, Gerard, Jun and Summerlin (2000) found that by the establishment of selective harvest strategies of prawn, Macrobrachium roesnbergii , the overall production per unit of time or space can be increased. A similar observation was made by Rodriguez, Trino and Minagawa (2003); the survival and net production of mud crab Scylla olivacea reared in ponds were more sensitive to the harvesting regime than to the diet. Moss, Otoshi and Leung (2005) tested partial harvesting in a super‐intensive recirculating shrimp production system.…”

The e¡ect of partial harvest strategies on the production of Artemia biomass was evaluated for 12 weeks under Vietnamese salt farm conditions. The initial stocking density was 100 nauplii L À 1 . After 3 weeks of inoculation, Artemia adults were partially harvested at intervals of 1, 3, 6 and 9 days starting with an initial quantity of 30 kg ha À 1 day À 1 at ¢rst harvest, and then the quantity of harvestable biomass was adjusted according to the standing stock present in the culture pond, combined with the time needed to harvest these quantities and with the weight of biomass harvested in each pond. The results showed that in most cases, the total densities were not significantly di¡erent among harvesting frequencies (P40.05). However, a relatively higher Artemia adult density and its standing stock were better maintained in the 3-day than in the 1-day interval, and were signi¢cantly higher compared with the other two harvesting frequencies. The total biomass yields were the highest (1587 kg ha À 1 ) in the 3-day harvesting interval, followed by 1-, 6-and 9-day harvesting interludes, corresponding to 1323, 1091 and 975 kg ha À 1 respectively. However, no statistical difference was observed between the 1-and the 3-day interval as well as between the 6-and the 9-day harvest schemes (P40.05). The results of this study suggest that partial harvest of Artemia biomass performed every 3 days appears to be an appropriate strategy to enhance biomass productivity.Values with di¡erent letters (a^c) in a row are signi¢cantly di¡erent (Po0.05). The numbers within parenthesis indicate the degree of freedom (d.f.) between groups and within groups respectively.

“…Since then, there have been few reports on growth rates for wild Scylla spp. (Thomas et al ., ; Moser et al ., ; Walton, ; Walton et al ., , ; Le Vay et al ., ), and most data were obtained from pond culture experiments (Agbayani et al ., ; Fortes, ; Trino et al ., ; Rodriguez et al ., ; Christensen et al ., ). Only one previous study reports growth for wild crab in terms of ‘ k ’, the von Bertalanffy growth constant (Le Vay et al , ) and this suggested that S. paramamosain in the Mekong delta grew slightly faster ( k = 2.39) than the Ibajay S. olivacea population ( k = 2.19), although the better fitting Gompertz model indicated a k of 3.29.…”

1. Small-scale fisheries are an important element of the ecosystem goods and services that mangrove habitats provide, especially to poorer coastal communities that rely most on natural resources, and have similar values to payments for ecosystem services (PES) under carbon-trading schemes.2. In advance of fishery-enhancement trials for the mud crab Scylla olivacea, a mark-recapture study was conducted to estimate population size and turnover in 50 ha of isolated mangrove on Panay Island, Philippines. A total of 811 crabs were released in six sessions with an overall recapture rate of 41.5 AE 3.6%. Population size ranged from 607-1637 individuals.3. There was a high degree of site-fidelity, with 45.5% of recaptures in the same sampling areas as releases. Total mortality was 0.79 month -1 , with fishing mortality accounting for 95% of overall mortality. 4. Von Bertalanffy and Gompertz growth models yielded estimates for L 1 (carapace width) of 117.3 AE 14.7 and 110.6 AE 2.1 mm and for k of 2.16 AE 0.74 and 3.25 AE 0.81, respectively. Crab densities of 12-33 individuals ha -1 in the study area were lower than in other mangrove systems owing to intermittent recruitment, while growth rates indicated no limitation in terms of food supply.5. The study demonstrates that in specific mangrove habitats that are below carrying capacity, there is potential for fisheries enhancement to sustain or increase direct economic benefits from mangrove ecosystems and hence promote community engagement in broader conservation and PES initiatives.
