The level of viability of milkfish (Chanos chanos) in transportation containers with different temperatures
No full textThe transportation of milkfish (Chanos chanos) is an important factor determining the survival of milkfish (Chanos chanos). The hatchery is not always close to the location of the aquaculture pond, so the treatment in transportation using land and sea vehicles to arrive at the aquaculture site/pond. This study aims to determine the effect of different temperatures in milkfish (Chanos chanos) transportation to obtain a good temperature in milkfish (Chanos chanos) transportation. The research method uses a completely randomized design (CRD) with three treatments and three replications. The treatments given were treatment A (temperature 15oC), treatment B (temperature 18oC), and treatment C (temperature 21oC). While the time taken for each treatment is 14 hours. The results showed that the survival of milkfish (Chanos chanos) were in the range of 90.04% (treatment A), 95.04% (treatment B), and 88.67% (treatment C), where the highest survival in treatment B is 95.04%

Growth and survival rate of vaname shrimp (Litopenaeus vannamei) at various doses of fertilizer
No full textWhite shrimp (Litopenaeus vannamei) is considered able to replace black tiger shrimp (Penaeus monodon) as a positive diversification. Excellence shrimp vaname (L. vannamei) is a high nutritional value, fast growth and able to use the water column as a place to live so it can be maintained with high stocking density. Natural feed (phytoplankton) can be stimulated through fertilization. The study was carried out at the Ghonebalano Coastal Fish Seed Center (BBIP), aiming to determine the effect of using different doses of urea and TSP fertilizer on the growth and survival of vaname shrimp (L. vannamei). The study used a Completely Randomized Design with three levels of combination treatment of fertilizer doses, namely treatment A urea 0.5 g/TSP 0.7 g; treatment B Urea fertilizer dose 0.7 g/TSP 0.9 g and treatment C dose Urea fertilizer 0.9 g/TSP 1.11 g. The results showed that the highest growth was obtained in treatment B i.e. 1.54±0.16 g/individuals, compared with treatment A (1.11±0.08 g/individuals) and treatment C (1.32±0.10 g/individuals). Survival in treatment A was 71.11±3.85%, treatment B was 73.33±6.67% and treatment C was 75.55±3.85%. Analysis of variance at the 95% confidence level (α0.05) showed that the administration of urea and TSP fertilizers differed significantly (0.05>0.03) on growth, but did not significantly influence (0.05<0.58) on the survival of vaname shrimp larvae
Growth and survival rate of white shrimp (Litopenaeus vannamei) at different density
No full textVaname shrimp is one of the fishery products that are expected to produce foreign exchange for the country besides tiger shrimp. One factor that can affect the growth and the production of vaname shrimp culture is dense stocking. The research was conducted in October-December 2016 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, aims to determine the effect of different stocking density on the growth and survival of vaname shrimp. The research was using Completely Randomized Design with three treatment levels of density, i.e. treatment A = 10 individuals per container, treatment B = 15 individuals per container and treatment C = 20 individuals per container and three replications. The results showed that the highest growth was obtained in treatment A which was 1,563 g/individuals, compared with treatment B (1.189 g/individuals) and C treatment (0.834 g/individuals). Survival rate in treatment A is 80.00%, B treatment equal to 75,56% and treatment C equal to 70,00%. Analysis of variance at 95% confidence level (α0.05) showed that the different density had a significant effect on growth, but had no significant effect on survival rate of the vaname shrimp larvae
Growth and survival of post larvae of tiger shrimp (Penaeus monodon Fabr.) through the administration of probiotics with different doses
No full textOne of the factors that affect the growth of tiger shrimp is the quality of feed. Nutrient content in feed such as protein, carbohydrate and fat, generally used as a parameter of feed quality. Feed consumed by shrimp is not all digested, one of which depends on the enzymatic ability of the shrimp digestive tract. The use of probiotic bacteria in addition to having the ability to reduce colonies, inhibit the growth of pathogenic bacteria, and neutralize water quality, probiotic bacteria can help digestibility of the intestine. The aim of this research is to know the growth and survival of post larvae of shrimp (Penaeus monodon Fabr.) Through the provision of probiotics with different doses. The research was conducted at Balai Fish Fishing Hall of Muna Regency, Southeast Sulawesi, Indonesia. Post larva shrimp tiger (PL-20) of 120 tails, maintained for 28 days. The tested treatment was probiotic dose 5 ml (treatment A), dose 10 ml treatment B), dose 15 ml (treatment C), and without probiotics (control). Probiotics are given every 7 days on water maintenance media using a pipette (0.5-20 ml scale). Weighing results showed relatively high post-larva shrimp larvae growth of 400.00% (treatment B); 291.67% (treatment C); of 233.33% (treatment A) and equal to 58.33% (Control). Variation analysis result showed that giving of probiotic with different dose gave real effect (P<0,01) to relative growth of postlarva prawn weights (P. monodon Fabr.). Provision of probiotics has no significant effect on postlarva tiger prawn survival rate (P. monodon Fabr.). The survival rate of post larvae of tiger shrimp during the study was in the range 66.67-83.33%

No full textSkeletonema costatum one type of phytoplankton commonly cultivated in the shrimp hatchery (Penaeus monodon Fabr.). Plankton S. costatum has a high nutrient content, small size is used as a natural feed of tiger shrimp larvae, especially in the zoea to mysis stadia. The aim of this research is to know the effect of inorganic fertilizer (NPK+Silicate) with dosage of 5 ppm, 15 ppm and 20 ppm to the density of S. costatum on tiger shrimp. The study was conducted for 2 weeks in July 2011 at UPTD Balai Benih Ikan Pantai Muna, Ghonebalano village, Duruka district, Muna regency, Southeast Sulawesi. The experiment used a 3-liter volume on stoples, a salinity water of 20 ppm. The study used Completely Randomized Design (RAL) with NPK and Silicate treated fertilizer with 5 ppm, 10 ppm (control), 15 ppm and 20 ppm with 3 replications. The initial density of S. costatum was 10,000 cells mL-1 per unit. The data were analyzed by ANOVA using IBM SPSS Statistic 22. The results showed that inorganic fertilizer application (NPK+Silicate) with different dose gave a very real effect on the density of S. costatum cells. Treatment of 15 ppm fertilizer dosage was significantly different with control and other treatment, average cell density was 121,000 cells mL-1. Based on cell growth, the 15 ppm fertilizer dosage has the best growth with an average cell increase of 1,2705 cells mL-1 day-1.Skeletonema costatum salah satu jenis fitoplankton yang umum dibudidayakan dalam pembenihan udang windu (Penaeus monodon Fabr.).
