Abstract

Purse seines are a type of fishing gear that operates by surrounding schools of fish. The target fish caught from purse seines themselves are small pelagic fish that are in schools. One of the areas where the majority of fishermen use purse seines is PPS Kendari, where the target fish caught are scallops, skipjack tuna and tuna. The price of self-caught fish is influenced by the type, size and quality of the fish itself. One of the reasons for the feasibility of a fishing business can be assessed from the opinions obtained from the business carried out. Having data related to the performance of catches from a fishing business will provide an initial picture regarding the feasibility of the fishing business. Data collection was carried out by participating in KMN Diva Bahari fishing activities made 8 fishing trips (1 trip 5-8 days). Then fish samples are taken for each fishing operation and the type, number and size are seen/measured. The data that has been collected is then presented in tables and figures and then compared with literature studies regarding the size of fish worth catching. Based on data obtained in the field, it was found that the fish caught were gliding (the majority), tuna, mackerel, sunglir, baby yellowfin tuna and skipjack. Where all the tuna, skipjack, sunglir, tuna fish that were caught were not yet worth catching. Meanwhile, for mackerel, blue kites are included in the fish size category worth catching. Several things that influence the size of fish caught that are not suitable are catching in FAD areas where one of the functions of FADs is a place for spawning and rearing, fishing seasons and fish areas.

Abstract

It is feared that the high level of human activity in the coastal areas of Dumai City and Bengkalis City will have a polluting impact on water quality conditions. Therefore, to preserve coastal and marine functions, it is necessary to manage the quality and control of sea water pollution for present and future purposes as well as ecological balance. This research aims to determine the water quality of Dumai City and Bengkalis City, focusing on the concentration of several physical and chemical water parameters listed in the sea water quality standards for marine biota. Water quality sampling was carried out in May-August 2023 at 12 research stations, then the results were compared with sea water quality standards for marine biota. The research results show that the parameters that still comply with sea water quality standards for marine biota based on the Decree of the Minister of the Environment No. 51 of 2004 are temperatures in the range of 28.7-30.8˚C and an average value of 29.45˚C., pH ranged from 6.4–7.2, with an average value of 6.9 and dissolved oxygen (DO) ranged from 5.0 – 5.9 mg/l, with an average of 5.34 mg/l. Meanwhile, the parameters that do not comply with quality standards are low brightness ranging from 0.40 m-0.58 m with an average brightness of 0.47 m and salinity ranging between 22-28 ppt, with an average salinity of 24 ppt

Abstract

The waters of Dumai City, located in Riau Province and directly connected to the Malacca Strait, are highly accessible both locally and internationally. The coastal area is characterized by intensive human settlements and diverse industrial activities, including oil and gas, crude palm oil (CPO), and cement industries, which discharge wastes that may affect marine biota. Most of these wastes are transported to the sea through river flows, posing a serious threat to the ecological balance and aquatic organisms, particularly fish, with potential risks to human consumers. This study aimed to examine the physicochemical parameters of the waters and to determine the concentration and status of cadmium (Cd) and lead (Pb) in water, sediment, and fish. The research was conducted from April to June 2025 using survey, observation, and experimental methods in both field and laboratory settings. Data were analyzed using Atomic Absorption Spectrophotometry (AAS) to measure the actual concentrations of heavy metals. The results were compared with the threshold values established by the Indonesian Ministry of Environment Decree No. 51/2004 concerning marine water quality standards for aquatic biota. The findings revealed that the physicochemical parameters, including water temperature, salinity, and dissolved oxygen (DO), remain supportive of aquatic life according to the standards. However, the concentrations of Pb and Cd in water, sediment, and fish samples exceeded the permissible limits, indicating pollution in Dumai waters.
