Abstract

Development of squid culture is one effort to prevent the decline of squid population in nature due to continuous capture. Problem faced in the aspect of squid culture is the unavailable information regarding the culture technique of squid in controlled tank. This research was conducted to evaluate the hatching rate of mitre squid Uroteuthis chinensis, and survival of larvae in the controlled tank. The result showed that the hatching rate in culture tank was high, i.e 95.92%, while the survival rate of larvae after hatching was relatively low, only reached 4.25%. The low survival of squid paralarvae was expected because of the administration of single live food which resulted in the low predator response and imbalance of nutrient intake for the development and growth of paralarvae

Abstract

Sebongkok Island is one of a small island with a high potential mangrove resource with an equitable distribution. Communities around the Sebongkok Island used it inefficiently. The problems might because of lacking information (database) regarding the assessment of inventory, identification and mangrove structure vegetation, both derived from the research of academics, NGOs, government agencies and other institutions that engaged in the field of sustainability environment. Therefore, this research is important for mangrove sustainability. This study aims to: 1) determine the diversity and density of the mangrove species at the SebongkokIsland and its relation with abiotic components, 2) determine the status and condition of mangrove ecosystem on the Sebongkok Island. Our study revealed that the mangrove vegetation found in Sebongkok Island consists of 7 mangrove species, 5 families. The mangrove species that the most dominate and play an important role was R. apiculata, R. stylosa, and R. mucronata.

Abstract

The consequences of tin mining activities is the formation large basin-shaped holes filled with water in which the local (Bangka Belitung islands) term is a Kolong or Camuy (lake). Heavy metal concentrations are still high in all the pits and endangering human health; is the image that is in today's society so that people refused to eat the fish from or doing aquaculture activities in kolong.Pb heavy metal in the jambal catfish start found in the second month, the month of December 2011 on the kidney and meat measured 0,032 mg/kg and 0,177 mg/kg, respectively. In the third month (January 2012) Pb was found in almost every organ of jambal above safe levels for consumption, ie 15,39mg/kg in liver, and 40,56 mg/kg in the flesh.Decrease in water temperature and pH also resulted in an increase of Pb accumulation in the meats of jambal catfish, which amounted to 40,56mg/kg. During the four months of cultivation, the accumulation of heavy metals Pb that occur in every organ of observation had a significant influence to the growth rate of jambal catfish. Accumulation of Pb in each jambal catfish organs in the first and second months of cultivation is almost immeasurable but still lowering the rate of growth since the first month. The jambal catfish body already polluted with the heavy metals, as evidenced by Pb measured in the meats and kidney in the second month of cultivation.

Abstract

One of the most species that using in seaweeds farming is Gracilaria sp. The success of farming, is determined by several factors such as plant spacing. The aim of this study is to determinine the best plant spacing for seaweeds farming and water quality of farming location. The study was held in the village of Kahyapu, Enggano Island, Bengkulu province from March until May 2015. The research was held using experimental methods that refers to Meylia (2015). Seaweeds is grown using three plant spacing (20, 25 and 30 cm) for 42 days. Wet weight of seaweeds was measured every week. Water quality was measured at the beginning, middle and end of the study. Data of wet weight and absolute growth rate were analyzed using a completely randomized design (CRD) factorial at the 95% confidence level with two factors, plant spacing and farming periode. Duncan Multiple Test (DMRT) was used if there is a significant difference. The results showed that the interaction between plant spacing and farming periode has siginificant effects to wet weight. Duncan test showed that more extensive planting space and the longer the cultivation, the wet weight will be higher. The rate of absolute growth is affected by plant spacing and observation times. Based on the Duncan’s test, wider spacing can increase the growth rate. Plant spacing of 30 cm is the best treatment. Water quality (temperature, salinity, pH, brightness and water current) during farming was suitable for seaweeds growth

Abstract

The purpose of this study was to find out the addition amount rate of carrageenan powder to the amount of sea catfish meat to produce the most preferred fish balls. The design used was a completely randomized design (CRD) with six treatments in adding carrageenan on the number of sea catfish meat (b / b) and 20 panelists as repetition. The six treatments were 0.0%, 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The parameters measured were the level of fondness based on the organoleptic characteristics which included appearance, aroma, texture and taste. The analysis used was nonparametric Friedman analysis, which followed by a multiple comparison test if there were differences on the treatments. The decision making was best done by using Bayes methods. The results showed that the addition rate of carrageenan powder at 1% of the sea catfish meat weight produced most preferred fish balls of other treatments
