This study aims to determine the effect of amphipod density on the growth, survival and molting of mangrove crabs (Scylla tranquebarica).The research was conducted in the Installation of Tiger Shrimp Hatchery (ITSH), located Lawallu Village, Soppeng Riaja District, Barru Regency, South Sulawesi, from May to June 2022. There was 45 mangrove crabs, with an average weight of 0.04 ± 0.005 g and a carapace width of 5.4 ± 0.1 mm which were obtained from local hatcheries. The maintenance container is a glass jar containing 0.5 liters of water, each jar is filled with one crablet. The treatments tested were differences in amphipods density, namely: A) 20 ind/0.5 L, B) 30 ind/0.5 L, C) 40 ind/0.5 L, feeding frequency is once a day for first 10 days and twice a day at 8:00 AM and 5:00 PM for next 20 days. Parameters observed were growth weight (GW) and growth carapace width (GC), specific growth rate-weight (SGR-W) and specific growth carapace- width (SGR-C), survival rate (SR) and number of molting (NM). Using a completely randomized design with three treatments and three replications, each replication consisted of 5 crabs. Data were analyzed for variance and Duncan's further test, physical and chemical parameters of water were analyzed descriptively. The results showed that amphipod density had an effect on GW, GC, SGR-W and SGR-C, but had no effect on SR and NM. Amphipod densities of 20 - 40 ind/0.5 L produced good survival and a large number of molting, but amphipod densities of 30 ind/0.5 L were more efficient for the growth of mangrove crabs.

“…This process produces simple peptides with high protein solubility (Yarlina et al 2020;Cruz-Casas et al 2021). Additionally, increased proteolytic enzyme concentration during hydrolysis leads to higher dissolved nitrogen content in protein hydrolysates (Aslamyah et al 2022).…”

Abstract. Anwar A, Zainuddin, Djawad MI, Aslamyah S. 2023. Fermentation of rain tree (Samanea saman) seed meal using mixed microbes to improve its nutritional quality. Biodiversitas 24: 5863-5872. Rain tree (Samanea saman) seed meal is a source of protein; however, its utilization remains limited due to the presence of anti-nutrients, such as tannins acting as protein inhibitors, high crude fiber content, dissolved protein, and low digestibility of dry and organic matter. Fermentation using mixed microbes potentially enhances the nutritional value of rain tree seed meal. This study aims to improve the nutritional quality and reduce anti-nutritional factors in rain tree seed flour using mixed microbes at various doses and incubation times in vitro. Microbes utilized in this study include Bacillus sp., Saccharomyces cerevisiae, and Rhizopus sp. The study was designed using a Factorial Completely Randomized Design, using two factors, i.e., 3 doses of mixed microbes (0, 1.5, 3, and 4.5 mL/100 g rain tree seed meal) and 3 different incubation times (42, 72 and 96 hours). There were significant interactions between the microbe doses and incubation times. The treatment of 4.5 mL of mixed microbes/100 g rain tree seed meal and a 72 hours incubation time reduced substantially crude fiber content (59.60%) and crude fat (73.20%), coupled with an increase in crude protein content (11.62%), NFE (6.52%), dry matter digestibility (DMD) (36.78%), organic matter digestibility (OMD) (50.42%), and dissolved protein content (20.27%). Tannin content reduced significantly (37.72%) at the treatment of 4.5 mL of mixed microbes/100g rain tree seed meal with an incubation time of 96 hours. These findings suggest that rain tree seed meal, subjected to fermentation for 72 hours or more, improves nutritional quality, DMD, and OMD.

“…The feed that is used in this study was artificial feed with fermented raw materials recommended by [11] and [12], with a nutritional composition consisting of protein, fat, crude fiber, NFE, ash, and energy with a concentration of 41.93, 7.43, 7.82, 29.33, 13.49%, and 2767.63 kcal/kg respectively. The feed was enriched with vitomolt by dissolving vitomolt with 50 mL of vitoferme and 20 mL of water for every 2.5 kg of feed.…”

Vitomolt is a feed additive in fattening mud crabs (Scylla olivaceae). The study aimed to determine the best dose of vitomolt for meat quality and nutrient retention for fattening Scylla olivaceae. It was conducted at the Educational Farm of Universitas Hasanuddin, Barru Regency, Indonesia. The treatments were various doses of vitomolt in the feed, which 0, 200, 400, 600 mg kg−1 of feed. Rearing was held for 60 days and fed 5% body weight daily. The analysis showed that the dose of vitomolt in the feed affected the percentage of meat carcass weight, fat content, fat retention, and crab energy retention. However, it did not affect protein content, crude fiber, Nitrogen-Free Extract (NFE), ash content, and crab protein retention. The best percentage of meat carcass weight at a dose of vitomolt 400 mg kg−1 and same from a dose of 200 mg kg−1, while the best fat content, fat retention, and energy at a vitomolt dose of 600 mg kg−1 and different from a dose of 400 and 200 mg kg−1, but different from the control. Vitomolt with a 200 mg kg−1 of feed is the best dose to produce the highest meat quality and nutrient retention in fattening crabs.
