Shrimp commodities in Indonesia have been cultivated, either traditionally, traditionally plus, semi intensive, or intensively. One type of shrimp that is constantly strived to increase its production is the shrimp vaname (Litopenaneus vannamei). The environmental conditions of pond waters are closely related to pond water quality. One of the water quality parameters affecting the survival and growth of vaname shrimp is salinity. The study was conducted from May to June 2018 at the Fish Seed Hall (BBIP) Ghonebalano, Ghonebalano Village, Duruka District, Muna Regency. This study aims to determine the effect of water salinity on different media on the survival and growth of vaname shrimp. The study used a Completely Randomized Design with four treatments and three replications. Treatment A salinity 20 ppt, B treatment salinity 25 ppt, C treatment salinity 30 ppt and treatment D salinity 35 ppt. The results showed that the treatment had significant effect on the survival of the animals in the 95% confidence level where the survival in sequence, the treatment of A 87.50%, the treatment of B 83.33%, the C treatment 80.56% and the treatment D 69.44% . The treatment also had a significant effect on the growth of test animal at 95% confidence level. Successive growth was, treatment A 2.01 g, treatment B 1.91 g, treatment C 1,71 g and treatment D 1.51 g.

The study aimed to determine the growth and survival of Litopenaeus vannamei shrimp with the application of probiotics to different stocking densities.  The study was conducted from May to June 2018 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, Duruka District, Muna Regency, using a Completely Randomized Design (CRD) with three levels of solid stocking treatment namely treatment A is 18 individu per container, treatment B is 24  individu per container and treatment C is 30  individu per container with three replications.  Data analysis using Variance Analysis (ANOVA) at the confidence level of 95% (α 0.05).  The results showed that the highest daily growth was obtained at 24 individual densities of 5.88% per day, compared to 18 individual densities of 5.86% per day and 30 individual densities of 5.74% per day.  The highest absolute growth is obtained at 24 individual density of 2.43 g per individu, then 18 individual density of 2.15 g per individual, and the lowest at 30 individual density of 2.02 g per individual.  Survival at a density of 18 individual and a density of 24 individual at 88.89%, while a 30-ind density of 86.67%.  Analysis of variance (α 0.05) showed that the application of probiotics to different stocking densities had no significant effect on the daily growth rate of vannamei shrimp (p<0.939), absolute growth of vannamei shrimp (p<0.080), and survival of vannamei shrimp (p<0.744).

Vannamei shrimp (Litopenaeus vannamei) is a commodity that is expected to not only increase options for farmers but also sustain the rise of shrimp farming business in Indonesia. One important factor in shrimp farming is the availability of feed. In addition to the availability of natural feed during cultivation, stocking density is also very influential in the survival rate and growth of shrimp vannamei. The research was conducted in September-December 2016 farms Bonea Village District of Lasalepa Muna with Test the different dosages with different stocking density. The study used a Random Group Factorial, which is based fertilization (Factor A) with three levels and stocking density (Factor B) as many as three levels, each with three replications so that all 27 units experimental unit. The results showed that the combination of factors dose of 0.7 g of urea + 0.9 g TSP and stocking density factor of 10 individuals per container provides prawn post larvae growth vannamei most excellent and a combination of factors Urea fertilizer dosage of 0.9 g TSP + 1.1 g and stocking density factor of 20 individuals per container provides a survival rate of post larvae vannamei most good. Water quality media for research in the range that is optimal for the growth and survival of post larvae vannamei.
