Main Dimensions Characteristic of Purse Seine Fishing Vessel in Lempasing Coastal Fishing Port Lampung Province
Get PDFMeasurement of the main dimensions of the vessel is very important to analyze thevalue at L/B, L/D and B/D which can affect to the strength, speed and stability.The limited information and data regarding the size at purse seine boats inLempasing fishing port can be an obstacle in the development of fishing activities.This research aims to describe and to analyze the characteristics, ratios andanalyze the relationship between the ratio of the main dimensions of purse seinevessels with engine power and purse seine nets that used in PPP Lempasing. Theresearch was conducted in February 2015-March 2016 at coastal fishing port ofLempasing. The method was used census and analyzed by descriptivecomparative. The results show the range of the main dimensions from 9.31 to18.50 meters of LOA, Bmax from 3.72 to 6,05 meters and Depth (D) from 0.82 to1.75 meters. The ratio of the main dimensions have a range 2.13 to 3.81 of L/B,the value of L/D from 7.69 to 13.46 and the B/D from 2.91 to 4.62. The ratio ofpurse seine has not been used in determining the engine power and the size offishing gear. The ratio of main dimension does not have a tendency relationship toengine power and fishing gear because fishermen have not considered it

The physics and chemist parametric in Labuan Terata Waters, Sumbawa at transitions season
Get PDFLabuhan Terata Waters, Sumbawa, West Nusa Tenggara is one of the waters are very important for Labuhan Terata peoples because function for fisheries, but asses water quality especially transitions season is minus. The research objective was to assess physics and chemist parametric in the Labuhan Terata waters at transitions season. Oceanographic research in the Labuhan Terata waters have been carried out in May to June 2015. Current, brightness, temperature, dissolved oxygen (O2), acidity (pH), salinity, phosphate and nitrate parameters was measured directly from a layer surface at five research stations. The degree of temperature was measured thermometer Hg, acidity (pH) was measured with pH meter, dissolved oxygen was measured dissolved oxygen meter (DO meters), measurement of nutrients (phosphate and nitrate) concentration used spectrophotometry method. Result of the analysis showed that Labuhan Terata waters has current range from 0.39–0.93 m.dt-1, temperature of 28.50–30.00 °C, brightness 4.00–6.55 m, salinity of 30.50–31.33 psu, dissolved oxygen of 10.40-12.83 mg.L-1, pH of 8.04 – 8.70, phosphate of 0.05 – 0.75 mg.L-1 and nitrate 2.83 – 4.50 mg.L-1

The total 84 swimming crab consist of 40 males and 44 females. With total weight 15,556 g. The carapace width distribution in this study ranged from 6,5 to 14,1 cm. The application of escaping gap have high effectiveness to catch the legal size of swimming crab with proportion 84%
Effect of Difference Incubation Temperature on The Hatching Time and Hatching Rate of Sinodontis (Synodontis eupterus) Eggs
Get PDFSinodontis is one of the ornamental fish that have high economic value, because of its unique behavior which could swim in reversed position. The purpose of this study was to determine whether there are differences in the effect of incubation temperature on hatching time and hatching time of sinodontis eggs, and to know the optimal temperature for the time of hatching time and hatching rate of the sinodontis eggs. The main parameters measured were the hatching time and hatching rate of sinodontis eggs. This experiment used completely randomized design with 4 treatment temperature difference, A (25-26oC), B (28-29oC), C (31-32oC) and D (control), with 3 replications. The results showed that the fastest hatching time of sinodontis obtained in treatment C at 1120 minutes (18 hours 40 minutes), then treatment B at 1240 minutes (20 hours 40 minutes), then treatment D at 1340 minutes (22 hours 20 minutes) and longest hatching time in treatment A at 1760 minutes (29 hours 20 minutes). Highest hatching rate of sinodontis obtained in A treatment that was equal to 94.67%, then C treatment that was equal to 82.67%, and treatment D amounted to 81.33% and lowest hatching rate in treatment B 80.00%. Based on the results of the study showed that the optimal temperature to accelerate the sinodontis for hatching time was at a temperature of 31-32oC, while the optimum temperature for increasing the hatchability of sinodontis eggs was at a temperature of 25-26°C
