This study aims to study the performance of phytoecdisteroids from mulberry leaves in molting stimulating of mangrove crabs. The research was carried out at the Research and Development Center for Aquaculture at the Faculty of Marine Sciences and Fisheries at Hasanuddin University, located in Bojo Village, Mallusetasi District, Barru Regency, South Sulawesi Province. Mangrove crabs (Scylla olivacea) weighing 45-55 g and carapace widths 60-65 mm were used as test animals. There were five doses of mulberry leaf extract applied through feed, namely: A) 1.1 mg / g feed, B) 1.9 mg / g feed, C) 2.7 mg / g feed, D) 3.5 mg / g feed. Crabs were kept individually in plastic boxes that are floated above the surface of the pond. During rearing, crabs are fed 3% dry fish per day which has been enriched with mulberry leaf extract. The parameters observed were ecdysteroid compounds contained in mulberry leaf extract, ecdysteroid content in hemolymph before and after application of mulberry leaf extract, and molting percentage. Identification of the ekdisteroid compounds contained in mulberry leaf extract was carried out using Thin Layer Chromatography (TLC) and Measurement of the content of ecdysteroids in crab hemolymh was carried out using Ultra Fast Liquid Chromatography (UFLC). The results showed that the 3.5 mg dose of mulberry leaf extract / g feed gave the highest increase in ecdysteroid hemolymph, which was approximately 1760 ekdisteroid per mL hemolimph, while the dose of 1.1 mg / g feed only provided an increase of 100 ng ekdisteroid per mL hemolymph. The higher the dose of mulberry leaf extract in the feed, the higher the increase in the concentration of hemolymph ecdysteroids, but the high concentration of ecdystoid in the hemolymph does not guarantee molting. The optimal dose of mulberry leaf extract in the feed stimulating molting was 2.4 mg / g of feed.Keywords: mulberry, phytoecdysteroid, molting, crab, aquaculture

The existence of mangrove in coast areas have both ecologic and physical important functions. Mangrove is a high productive ecosystem. Litters from fallen leaves and twigs are organic sources for macrozoobenthic life. The aim of this research was to determine the response of macrozoobenthics on total organic matter content and other chemical-physico characters of sediments due to differences in mangrove conditions. This research was conducted from May to September 2016 in Sub-district of Ampallas, Distric of Mamuju, Province of West Sulawesi, Indonesia. Sediments in 20 cm2 transects were collected using small shovel to obtain the macrozoobenthic samples. The sediments contained macrozoobenthics were sieved using a 1 mm mesh size sieve net. Four sampling sites were chosen, each to represent areas with no mangroves, low, medium, and high densities. The total of organic matter samples were collected using 2 inch diameter of PVC pipe cores, which were analyzed further using Loss by Ignition method. Besides total of organic matter, several parameters (i.e. redox potential, sediment pH, salinity, temperature, and dissolved oxygen) were measured. The results showed that gastropods dominated the existed macrozoobenthics. Gastropods and oligochaete lived in greater amounts in high mangrove density site with higher organic matter content and fine substrate.Keywords: mangroves, macrozoobenthics, organic matter, Distric of Mamuju

Zooplankton has an important role in waters, especially in the food chain, these organisms are consumers I which play a major role in bridging energy transfer from major producers (phytoplankton) to living things at higher trophic levels (fish and shrimp). This study aims to analyze the relationship between zooplankton abundance with phytoplankton and physicochemical parameters in the waters of Kastela, Ternate. The research was conducted from March to April 2017 in the waters of Kastela Ternate City North Maluku Province at 5 stations and 4 periods of sampling. Zooplankton samples were taken by filtering methods. The results showed that there were 20 zooplankton genera from 5 (five) classes namely Ciliate (4 genera), Crustaceae (8 genera), Hydrozoa (3 genera), Rotifera (3 genera), and Urocohordata (2 genera). Zooplankton abundance ranges from 1032 to 10942 cells.l-1, the highest at station 3 periods II (10942 cells.l-1), and the lowest at station 4 period I (1032 cells l-1). The range of values of the zooplankton biological indices is diversity index (0.5005 - 1.8662), uniformity index (0.6521 - 0.9601), and dominance index (0.1661 - 0, 6800). There was a low correlation between zooplankton abundance and phytoplankton abundance and physical-chemical parameters of water in Kastela waters, with determination coefficient is 0.236 and regression equation Y = 35079.107 + 0.030 phytoplankton - 791,251 temperature + 75,417 salinity - 1658,557 pH Keywords: mangroves, macrozoobenthics, organic matter

Toman fish seeds (Channa micropeltes) generally come from natural catches in South Kalimantan and Central Kalimantan. A closed system is an effort to efficiency transportation costs by increasing the density of fish in transport media. Efforts to reduce stress levels are very important so that they can transport a lot, have small deaths, and take a longer time, and do not disturb the physiology of the fish after transportation. The purpose of this study was to determine the effect of giving 3 ppt salt in transport media to the survival of fish during transportation. This research consists of two stages of activity, that is stage one is transportation for 12 hours and stage two was post-transportation maintenance for 11 days. In stage one, the plastic bag is filled with 10 L of water and is packed according to the treatment. This study used a Completely Randomized Design (CRD) with 4 treatments 3 refitition to produce 12 experimental units. K treatment density of 30 heads / bag with no salt water (0 ppt) and treatment A: B: C with density (30: 50: 70) tail / bag with salt water (3 ppt). The calculation of the highest survival rate in treatment A was 97.80%. The results of analysis of varians (ANOVA) that the treatment has a real effect on survival rate in fish seed transport toman. This shows the best density in this study is 30 heads / bag. Keywords: redsnackhead Fish, Channa micropeltes, transportation, salinity

The use of probiotics (Lactobacillus sp.) in feed is one alternative that is done to improve immunostimulants, growth stimulants, and can be used as a balance of microorganisms in digestion. This study aimed to evaluate the growth performance of vanamei shrimp fed with the addition of Lactobacillus sp. with sweet potatoes in feed. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment was by feeding with different sweet potato concentrations: A) The dose of sweet potato in feed was 0% (as control); B) The dose of sweet potato in feed was 10%; C) 1The dose of sweet potato in feed was 15%; and D) The dose of sweet potato in feed was 20%. Data were analyzed using variance analysis (ANOVA) and continued with W-Tuckey's further test. The research parameters were digestive enzyme activity, nutrient digestibility, and growth. The results of the variance analysis showed the addition of various sweet potato concentrations with Lactobacillus sp. has no significant effect (p> 0.05) of the growth rate. The specific growth rate of vannamei shrimp ranges from 3.06 to 3.23% / day. Based on the results of the analysis on the utilization of sweet potatoes as a prebiotic on the performance of Lactobacillus sp. in the vannamei shrimps (Litopenaeus vannamei) digestive tract can be concluded that the growth performance does not have a significant effect after being fed with the addition of Lactobacillus sp. and sweet potatoes in feed.
