“…This is following the statement that a fairly quiet flow is favored by white shrimp, especially in terms of feeding to support its growth. Distribution pattern criteria according to [7] can be grouped by morista distribution index values. If the value of the distribution index (Id) = 1.0, it can be said that the distribution of a population is categorized as random; if the value of the distribution index (Id) = 0, then the population distribution is categorized as normal; and if the distribution index value (Id) ≠ 1 or Id ≠ 0, then the distribution of the population is categorized as a group.…”

This study can be used as a basis for its management in the future. The purpose of the study was "Analyze the dynamics of white shrimp populations such as growth patterns, long frequency distribution, growth parameters, mortality rates, and recruitment patterns. The study was conducted for 12 months, from January-December 2021. The method used in sampling is purposive sampling, using a mini sine purse fishing gear measuring 8 m x 2 m. White shrimp growth patterns were analyzed using FISAT 2 software, shell length frequency distribution and growth parameters using von Bertalanffy growth models, asymptotic length and growth coefficient using the ELEFAN method, total mortality rate, natural and capture using Pauly's empirical equations, and recruitment patterns using the FAO-ICLARM program. The results of the study found the highest density of white shrimp at station 3 (257 ind / m2) and the lowest at station 2 (213 ind / m2). The distribution pattern of white shrimp at each station is in groups. The growth pattern of white shrimp is allometric negative. The theoretical lifespan at the length of zero carapace is 0.02 years or 0.2 months. The natural mortality rate of white shrimp is 0.75/year, the total mortality rate is 0.91/year and the catch mortality rate is 0.16/year. The capture of white shrimp in the waters of Karang Gading Deli Serdang Regency, North Sumatra is still under exploitation. Peak recruitment was in May and June (18.92% and 18.33%) after four months of white shrimp spawning.

Dried anchovies (Stolephorus sp.) are one of the widely consumed fishery products, both in the domestic market and the export market but has the disadvantage of being easily spoiled if not consumed immediately or processed further, so proper handling is needed to maintain quality. The goal of this research was to determine the physical, chemical, microbiological quality and quality conformity of Dried anchovies (Stolephorus sp.) in Belawan Production with Quality Standards. This study was carried out in February to April 2024. The results showed that the quality of dried anchovy on organoleptic values at each production site had a value of 7-9. Chemical quality obtained ash content value of 13.42%-16.53%, salt content of 7.11%-7.26% moisture content of 43.74%-52.11% and formalin content of 0 mg/kg. Microbiological quality includes Total Plate Count (TPC) of 0.9 x 105 -2.2 x 105 colonies/gram, Escherichia coli of <3.0 CFU/gram, and Staphylococcus aureus of <101 colonies/gram. The quality of dried anchovy based on Quality Standards for organoleptic values, salt content, moisture content, Escherichia coli, Staphylococcus aureus and Total Plate Count (TPC) in Production Unit 3 and Ship 3 has met the quality standards.

Fish meal is an important part of raw material for fish feed. However, the use of fish meal is considered unsustainable, compete with human being and expensive. By product of Anchovy (Stolephorus sp.) which contains high protein is potential to be used to replace fish meal. Present study aimed to determine the utilization of anchovy by-products raw materials as feed ingredient for seurukan fish (Osteochilus vittatus) and evaluate its effect on the growth performance and intestinal morphology. In total 250 seurukan fish (initial weight 0.67 ± 0.01 g) was randomly divided into four triplicates groups: control group, and experimental diets which had different inclusion level of anchovy by-products meal: 50%, 35%, and 20%. Fish were fed with different diet at level of 8% of body weight three times a day for 28 days. Present results showed that the inclusion of anchovy by-product meal in the feed by 50% can produce a higher value of weight gain (0.47±0.02 g), length gain (0.69±0.09 cm), SGR (2.20±0.51%) and feed efficiency (77.89±3.71%) compared to control feed (p<0.05). There was no significant difference in the survival rate and gut length ratio among groups of seurukan fish. Meanwhile, the average villi length and villi width of the seurukan fish fed experimental groups increased significantly compared to the control group (p<0.05). In conclusion, the 50% anchovy by-products meal inclusion in the diet of seurukan fish is beneficial to enhance growth, feed efficiency and improved feed absorption as indicated by histological analysis.
