Survival rate and growth of juvenile vannamei shrimp (Litopenaeus vannamei) in different media water salinity 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.

Mapping of fishing area (Euthynnus affinis) GIS based in Bone’s Bay Waters The purpose of this study was to identify the relationship between oceanographic factors and the catch of tuna (Euthynnus affinis) and to determine the potential fishing zone (ZPPI) in the waters of the Gulf of Bone. The data collection method is carried out by literature study and field observation study by taking coordinate points and measuring oceanographic parameters. The types of data collected were temperature, salinity, currents, and tuna catches. Data were analyzed using GIS software with the Kolmogorov-Smirnov normality test and ANOVA test. This research was conducted in Bone Bay Waters in October-November 2018. The results showed that the highest catch based on sea surface temperature was in the range of 32°C with a total yield of 1207.5 kg, the highest net based on salinity was in the field of 34‰, namely as much as 836.5 kg, and the highest catch is based on a current speed of 0.04 m/sec, which is as much as 334.5 kg. Based on the ANOVA table, the significance value of the effect of temperature (X1), salinity (X2), and current (X3) simultaneously on the tuna catch (Y) is 0.0425<0.05 and the Fcrit>Ftabel (5.960>4,75) which means that there is a significant effect of oceanographic parameters on the tuna catch. Overlay analysis of oceanographic parameters shows potential areas for Euthynnus affinis is located most of the waters of Sinjai to the south of the Sembilan Island to the outside of Bone Bay.
