Abstract

This study aims to determine the effectiveness and differences in the results of different types of Mesh sizes using Basic Gill Net Fishing Equipment (Bottom Gill Net) on fish catches, and to determine the composition of the types of fish caught. The method used in this study was an experimental method with a completely randomized design (CRD). The research was carried out in the waters of Puyahan Hamlet, Lembar Selatan Village, Lembar District, West Lombok Regency. The results of the study based on Sidik Diversity Analysis (ANASRA) showed that there was a "very significant" different effect on the different Mesh size type treatments in units of weight (kg) where (F count 10.43 > F table 1% 5.95). The results also showed that the types of fish caught during the study used 4 types of mesh sizes on basic gill nets, with the most in treatment 1st repetition 3 as much as 4.9 kg and the least in treatment 4th repetition 2 as much as 1 kg. overall the highest catch was obtained in treatment 1 (mesh size 1.5 inches) as much as 16.9 kg (36.03%) and the least was obtained in treatment 4 (mesh size 2.5 inches) as much as 7.4 kg ( 15.80%). The types of fish caught are: Lemuru, Rajungan, Grouper, Tembang, Beronang, Layur), white pomfret, seed jackfruit/kuniran, Tiga waja.

Abstract

The purpose of this study was to determine the susceptibility of catfish to Aeromonas hydrophila bacteria, and to know the blood picture of catfish infected with Aeromonas hydrophila bacteria. The method used in this study used an experimental method with a Completely Randomized Design (CRD) or Competely Randomized Design (CRD) (Gomez and Gomez, 1984) with 4 (four) treatments and one control each with 3 replications. The results showed that catfish had a strong susceptibility or resistance to Aeromonas hydrophila bacteria. The Lethal Dose value of 50 was 106 cfu/ml, meaning that Aeromonas hydrophila bacteria was able to kill 50% of the catfish population when it was 5.4 x106 cfu/ml. The lowest average red blood cell count was in treatment A, which was 23.89x106 cells/mm3 and the highest in treatment D, which was around 37.5x106 cells/mm3, while the highest and lowest mean total leukocyte counts were 43.07-82.72x103 cells/mm3, still within the range of values. normal. The average hemoglobin concentration was lower than the normal value range in treatment A, which was 6.52 gr% and in treatment D, it was around 12.42 gr%

Abstract

Water pH is an important external factor for the success of hatching fish eggs. PH stimulates the chorionase enzyme to be more active, it can soften the egg chorion. The purpose of this study was to determine the optimum pH value for Pangasianodon hypophthalmus hatching eggs. This research was conducted at the Batu Kumbung Fish Seed Installation, Lingsar, West Lombok. The research design used a completely randomized design with 5 treatments and 3 replications. Treatments are P1 (pH6), P2 (pH7), P3 (pH8), P4 (pH9) and P5 (pH10). The results showed that the different pH values of the water had a significant effect on the hatching percentage and the survival of Siamese catfish larvae. The highest hatching percentage (77.54%) was in the pH 8 treatment, the highest Siamese catfish larvae survival rate (95.12%) was in the pH 7 treatment which was not significantly different from pH 8 which produced 94.54%.
