This research was conducted in Pangandaran District, precisely at the Fish Landing Port (PPI) Cikidang Pangandaran. This PPI Cikidang is included in the type D fishing port of the Fish Landing. The research method used is a case study with data analysis using a Likert Scale. The aim of this research is to describe the role of PPI Cikidang through basic port facilities on the socio-economic characteristics of Pangandaran fishermen who work at PPI Cikidang. Based on observations and interviews through questionnaires, some of the main port facilities are still not optimal in their development and function. This affects the catches of fishermen and the activities of fishermen at the port. Some basic facilities that are still not optimal make fishermen more independent in activities without having to wait for facilities to be repaired or developed. The main facilities that have not been optimal are the pier, harbor ponds and fish markets. At the docks and port ponds there needs to be improvement by dredging the bottom of the water so that it can get inside, the tides can be conditioned. In the fish market, its function is still less than optimal because it is only used as a canteen. The improvement is to re-socialize the function of this fish market and try to carry out its function properly by increasing the fisheries business budget around PPI Cikidang.

The research aims to determine the best stocking density in the maintenance of Siamese catfish seedlings based on the influence exerted on the survival of Siamese catfish seeds and improving water quality in the recirculation system. This research was conducted at the Green House Ciparanje FPIK Unpad Jatinangor in August 2019. Maintenance activities are carried out in a 70x70x70 cm fiber equipped with a recirculation system and filled with 150 L of water per fiber. The study was conducted with four stocking solid treatments as follows 375 fry/fiber (treatment A); 450 fry/fiber (treatment B); 525 fry/fiber (treatment C); and 600 fry/fiber (treatment D). Siamese catfish fry is 1 inch in size with an average weight of 0.307 grams. The parameters observed were the survival of Siamese catfish fry and water quality. Water quality measurements include temperature, degree of acidity (pH), and ammonia (NH3). Water quality testing was carried out at the Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. During the study, there was no exchange of water or siphon. The method used in this research was analyzed descriptively and compared the results of survival rate fish and water quality parameters toward the Indonesian National Standard (SNI). The results showed that the best stocking density was 600 fry/fiber with a survival rate of 100% Siamese catfish and the ammonia value at the beginning of maintenance was 0.140 mg/L and the end of maintenance decreased to 0.137 mg/L.

This study aimed to investigate the levels of lead (Pb) and Cadmium (Cd) in water and fish muscle obtained from Elshajara area - Khartoum - Sudan. This area is located near one of the important factories in the country and is also an important fishing site.

A total of 60 samples (30 water and 30 fish muscles) were obtained from 3 different sites in the targeted area. The levels of Pb and Cd were measured using Atomic Absorption   Spectrometry.

The overall mean level of Pb and Cd in water samples were 0.148±0.0104 µg/l and 0.014±0.002 µg/l, respectively. Regarding the fish samples, the levels of Pb and Cd were 0.28480±0.018 µg/kg and 0.027±0.004, respectively. The levels were below WHO acceptable limits.

The level Pb and Cd in water and fish obtained from area B   were the highest because this site is  closest to the factory effluent site and thus the high levels.

Adopting proper water disposal systems for factories and other industrial facilities is necessary to avoid contamination of the ecosystem. This may in the long run affect the human health through consumption of food contaminated with such metals.

This research aims to determine the optimum dose of potassium diformate (KDF) which is added to commercial feed to improve the immune performances of giant gourami fingerlings. The research was conducted in October – December 2019 in Aquaculture Laboratories and Biotechnology Laboratory of the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The method used in this research is Completely Randomized Design (CRD) with four treatments and four replications. The treatments are addition of potassium diformate in feed with a dose of 0% (A), 0,3% KDF (B), 0,5% KDF (C) and 0,8% KDF (D).The giant gouramimaintained for 40 days. The observed parameters are total leukocytescount, total erythrocytescount, differential leukocytes, and water quality. The data of total leukocytes, total erythrocytes were analyzed using ANOVA and followed by Duncan’s Multiple Range Test, while differential leukocytes and water quality are analyzed descriptively. The results showed that the addition of 0.3% potassium diformate is the most effective to improve the immune performances of giant gourami fingerlings. During 40 days of treatments, total leukocytes count increased 25% from6.55×104 cells/mm3 to 8.74×104 cells/mm3, total erythrocytes countincreased 10.03% from 1.28 ×106 cells/mm3 to 1.43×106 cells/mm3. Potassium diformate treatment 0.3% was an effective dose to stimulate differential leukocytes of gourami fingerlings are triggered to enhance the immune system.

This research aims was to determine the effective pressure on fine bubbles technology on the growth of Siamese catfish fry in the aquaponic system. This study uses a completely randomized design with four treatments and three replications. Treatment A (Control), Treatment B (FBs at a pressure of 4,5 atm), Treatment C (FBs at a pressure of 5 atm and treatment D (FBs at a pressure of 5,5 atm). The parameters observed were Specific Growth Rate, Survival Rate and water quality (Temperature, pH, DO, Ammonia) Data were analyzed using variance with the F test at a 95% confidence level. The best treatment for catfish growth was treatment D (5,5 atm pressure), which gave the highest SGR value of 7,24% and the highest SR value of 100%. The value of water quality parameters were in good condition for the growth and survival of catfish.
