Abstract

The study aimed to determine how the growth and survival capabilities of vaname shrimp larvae (Litopenaeus vannamei) are affected by different feeding methods and thereby the most efficient method. The study was conducted at the PT. Citra Larva Cemerlang, South of Kalianda in Lampung Province. For the experiment Completely Randomized Design (CRD) was utilized with 3 feeding methods and each was replicated 3 times. The feeding methods tested were: fozen, liquid and powdered Artemia feed. The experiments were done with up to 5000 shrimps on Zoea 1 stadia per month, which were kept in rearing tanks for 17 days.The test parameters observed were absolute growth, specific growth rate, efficiency of feed utilization, survival rate and water quality. Based on the results of statistical analysis (Anova) feeding frozen Artemia gave the best results with absolute growth of 5,6 mg, daily growth rate of 0,33 mg/hari, efficiency of feed utilization of 0,27%, and survival rate of 72,9%. Water quality during maintenance temperatures obtained is 27,1-32oC, pH 7,73-8,26, dissolved oxygen 3,8-7,1 mg/l, salinity 30-34 ppt, ammonia 0,02-1,57 mg/l. Keywords: Litopenaeus vannamei, Artemia, growth, frozen, powder, liquid.

Abstract

This study was aimed to examine the level of utilization of artemia frozen and decapsulated artemia feed for growth and survival of vaname shrimp postlarva. The experimental design used a completely randomized design (CRD) with three treatments and three replications. The treatments tested were (A) Frozen Artemia, (B) Decapsulated Artemia, (C) Frozen Artemia + Decapsulated Artemia. Research carried out using 6300 PL2 vaname shrimp. Observed parameters include length growth rate and relative weight, feed utilization efficiency,protein efficiency ratio, survival rate and water quality. Feeding frozen artemia provides the best results with a growth in relative weight 128.06 g, feed utilization efficiency of 0.04%, protein efficiency ratio 48.21%, survival rate with a percentage of 56%, and for the relative length growth rate of artemia frozen + artemia decapsulation has the best results of 17.0%. Keywords : Artemia, tilapia, feed, growth

Abstract

The obstacle in vaname cultivation is the high death rate due to cannibalism. The effort that can be done is giving tryptophan. Tryptophan as serotonin synthesis in the brain so that it helps suppress the level of aggressiveness thereby reducing shrimp cannibalism. The purpose of this study was to analyze the level of cannibalism, growth and survival of vaname shrimp fed tryptophan in feed, and to determine the optimal dose in the addition of tryptophan to comercial fed. Design in this research used a completely randomized design consisting of 3 treatments and 4 replications: (A) Control (without tryptophan), (B) 1,0% tryptophan/kg feed, (C) 1,5% tryptophan/kg feed. Parameters observed were cannibalism rate, absolute weight growth, survival rate, feed conversion ratio and water quality. The results showed that the addition of tryptophan to commercial feed had a significant effect (P?0.05) on each treatment. Treatment C, which is the addition of 1,5% tryptophan, is the most optimal treatment where the vannamei shrimp cannibalism rate has the lowest value of 2,50%, absolute weight growth of 0,38 grams, survival rate of 94%, and feed conversion ratio of 0,50. Water quality parameters are in a good range for vaname shrimp culture. Key words : canibalism, tryptophan, Vannamei shrimp

Abstract

Vaname (L.  vannamei  ) shrimp cultivation is currently experiencing problems, one of which is disease caused by Vibrio bacteria, especially V. parahaemolyticus. This type of vibrio is the cause of white feces disease and AHPND in shrimp. Disease control due to Vibrio can be done by utilizing plants that have active compounds as natural antibacterials that are environmentally friendly. Mangrove plants have several active compounds that have great potential as antibacterial. This study aimed to examine some parts of the mangrove plant R. apiculata in inhibiting the activity of V. parahaemolyticus. Three parts of the mangrove plant, namely: roots, stems, and leaves were extracted using methanol. The three extracts were tested for their antibacterial activity against V. parahaemolyticus by several tests such as phytochemical, sensitivity, zone of inhibition, best dose, and toxicity tests. The test results showed that R. apiculata mangrove stem extract had the greatest ability to inhibit V. parahaemolyticus with an effectiveness value of 15.85% with the best dose of 200 mg/L. Toxicity testing using vaname shrimp larvae extract showed that mangrove stems were non-toxic with an LC50 value of 2,155.5 mg/L.Keywords: White feces disease, AHPND, active compounds, extracts, antibacterials
