“…This indicates that there is an effective grazing process in the pond ecosystem. Grazing is a process of low-level predation in the food chain model on aquatic ecosystems [31]. The existence of a grazing process and proportional water nutrient levels will greatly support the balance of aquatic biological ecosystems.…”

TAN (Total Ammonia Nitrogen) is the accumulation of nutrient elements needed by plankton to grow in intensive shrimp farming ponds. The purpose of this study was to determine the relationship effect of TAN concentration fluctuations on diatom abundance in the intensive shrimp culture cycle. This research was conducted during one intensive shrimp culture cycle at PT. Menjangan Mas Nusantara, Pandeglang, with its research variables is the dominance percentage of plankton abundance and the level of TAN solubility in ponds. The results showed that during the shrimp culture period the abundance of plankton was dominated by predominant diatom, chlorophyceae, and chyanophyceae classes. The percentage of diatom dominance during cultivation has a graph similarity with the level dissolved of TAN fluctuation in the pond. The dissolved of TAN itself is described continue to increase with shrimp farming age. Statically, the relationship between the dissolved effect of TAN concentration on diatom abundance in ponds was modeled by the regression equation y = 2.210 + 32.411 (R2= 0.88; α0.00). The conclusion obtained from the results of this study, the level of dominance by diatom abundance during shrimp culture period is strongly influenced by the fluctuation of TAN concentration as the main nutrient element in ponds with a significance level of 88%.

“…Kualitas air merupakan salah satu variabel penting dalam budidaya udang sistem intensif, karena kualitas air pada kegiatan budidaya udang bersifat dinamis dan fluktuatif sepanjang waktu (Ariadi, 2020). Kualitas air yang optimal akan menyebabkan situs ekologi budidaya berjalan stabil dan begitu juga sebaliknya (Wafi et al, 2021), sehingga kualitas air budidaya yang stabil dan sesuai dengan baku mutu air untuk kegiatan budidaya adalah hal penting yang harus diperhatikan oleh petambak udang. Kualitas air akan mempengaruhi produksi dan pertumbuhan udang vaname karena lingkungan yang baik akan mendukung pertumbuhan dan produksi serta begitu juga sebaliknya.…”

“…Fluktuasi pH harian yang tinggi harus dihindari selama kegiatan budidaya udang vaname di tambak intensif, karena fluktuasi pH harian yang tinggi dapat menyebabkan terganggunya kehidupan udang, sehingga udang mudah mengalami stres (Yunarty et al, 2022). Fluktuasi pH di ekosistem tambak terjadi, karena adanya perlakuan teknis yang berbeda pada masing-masing hari (Wafi et al, 2021).…”

This study aimed to determine the optimum stocking density that supported optimization of water quality and production of white shrimp (Litopenaeus vannamei) ponds. This study was conducted in 2 different cycles, namely cycles 14 and 15 and with different shrimp stocking densities in each cycle, namely 94 and 150 shrimp/m2. Each cycle and stocking density was represented by 2 ponds, namely ponds B5 and B6. Experimental animals used were white shrimp post-larvae stadia 9-10 (PL 9-10) with a size of 9-12 mm. Experimental parameters observed included water quality parameters (brightness, salinity, temperature, dissolved oxygen, pH, alkalinity, ammonium, and nitrite) and production performance (average body weight, average daily growth, biomass, feed conversion ratio, survival rate, and feed intake). Water quality of rearing medium reached the optimum value at a stocking density of 94 shrimp/m2. This was indicated by higher dissolved oxygen (4.0-5.3 mg/l) and lower ammonium (0.5-3.0 mg/l) compared to rearing ponds with a stocking density of 150 shrimp/m2 (4 0.0-5.0 mg/l; 1.0-3.0 mg/l). A stocking density of 94 shrimp/m2 showed a higher production performance than a stocking density of 150 shrimp/m2. This was indicated by the higher average body weight, average daily growth, and SR (18.20-19.77 g/shrimp; 0.30-0.48 g/day; 80.60-80.90%) and the lower FCR (1.11-1.33) at stocking density of 94 shrimp/m2 compared to 150 shrimp/m2 (17.18-17.40 g/shrimp; 0.45-0.50 g/day; 73, 92-78.32%; 1.64-1.75). The results of this study indicated that stocking density could affect water quality and shrimp production performance. The optimum shrimp stocking density in this study was 94 shrimp/m2.

“…Fishes when killed are not continuously and continually available, hence the need to preserve them from decay and spoilage (by maintaining the quality) until they are consumed or sold [3,4]. Various methods have been developed to meet this need; drying (dehydration), smoking, frying, salting, heating, roasting etc., most of which are practised in developing countries such as Nigeria.…”

The methods adopted to preserve fish can affect its nutritional quality owing to the likelihood of deposition of chemical and biological agents, which can also be injurious to health upon consumption. This study aimed to assess the impact of these preservation methods on the health of the people of Sampou. A descriptive cross-sectional study was conducted among people of Sampou, aged between 15-60 years. Data were collected from 364 respondents using interview and self-administered questionnaires and analyzed using Statistical Package for Social Sciences (SPSS) version 20. The study shows that smoking is the most common method of fish preservation in Sampou because it's easily accessible. Result of the study also revealed that fish preservation methods have health implications, such as burns, eye irritation, cough, asthma exacerbation, bronchitis, fever and chest pain. Although, smoking tends to prolong the shelf life of the fish it impacts adversely on health. It was recommended that farmers should seek support to build a solar powered cold room storage in Sampou, while the government should provide funds which will help fish farmers get better equipment. Medical officers and other healthcare workers should encourage regular medical screening and check up for fish farmers.
