Abstract

The addition of prebiotics to the diet can increase the availability of enzyme in thedigestive tract of fish. This study aimed to evaluate the effect of the different dose ofprebiotic to the growth and nutrition retention of tilapia. Four treatment and 3 replicates,namely: control (0% prebiotic), 1% prebiotic, 2% prebiotic and 3% prebiotic were usedin the experiment. The results showed that the addition of prebiotics in fed can promotebetter tilapia growth and nutrition retention compared to control. The highest specificgrowth rate was found in 2% prebiotic (4.10%), followed by 1% prebiotic (3.83%), 3%prebiotic (3.54%) and the lowest was in the control (3.34%) (P<0.05). The addition of2% prebiotics in the diet showed best result on promoting tilapia growth, feed efficiencyand nutritent retention

Abstract

Silvofishery based mangrove ecosystem based resource management has been alreadywidely known and practiced, both at home and abroad. However, until now it’s difficultto find silvofishery application with correct and proper principles, in terms of bioengineering, ecological and institutional. The researched was conducted on March2012. The aims of this study were (1) assess the ecological status, (2) assess fishaquaculture bioengineering, (3) economic and financial analysis for the silvofisheryapplication, and (4) determine the pattern of silvofishery management in RPH TegalTangkil.Collected data were related to ecological, economic, social and institutionalaspect, which related to silvofishery management in RPH Tegal-Tangkil. The researchshowed that, mangroves contribute significantly to the daily shrimp by product. Waterquality conditions currently were still suitable for fish aquaculture activities. Althoughthere were discovered heavy metals content in this area, there for it is necessary toimprove water quality by develop reservoir system. In terms of bioengineering, fishermanwere still culture fish by traditionally technique and not done with correct and properprinciples. Economically silvofishery system was still able to develop for increasefishermans incomes. If silvofisheries were applied properly, it can increase fishermanincome up to 509.60%. However, silvofishery management was still deficient; It is seenfrom the difference between the ideal and reality. Institutional improvement minawanamanagement system at least focus on the improvement of the organization and rules ofthe game.

Abstract

The coastal waters of Lontar Village is located in Tirtayasa District, Banten. The coastal waters of Lontar Village is also used for fishing activities that become the livelihood of the surrounding community. Communities around the coast of Lontar village dispose of household waste directly into the waters so that the waters become dirty. The existence of these activities can cause the condition of the waters to decrease even can lead to contamination. Decrease in water conditions will affect the living biota inside. Waters quality can be determined by measuring physical, chemical, biological and heavy metal parameters. Physical parameters include brightness, turbidity, and temperature. Chemical parameters are salinity, pH, dissolved oxygen, nitrate, phosphate, BOD, TSS. The biological parameter is total coliform. The parameters of heavy metals are lead and copper. The purpose of this study is to analyze the quality of coastal waters of Lontar Village based on physical, chemical, biological and heavy metal parameters. The results showed that most of the parameters of water quality (physics, chemistry, biology and heavy metals) are still in accordance with the value of water quality standards (Decree of the Minister of Environment No. 51 of 2004) only the value of lead metals exceeding the standard quality. It must be overcome so as not to disrupt the life of biota in the waters. Management that can be done is utilize aquatic biota that can absorb heavy metal content  such as green shell (shell should not be consumed), reducing oil spilled from the activityof motor boats (giving box shelter under motor boat engines so that oil does not directly spill into the waters).
