Abstract

The Gaung Fish Landing Base (PPI) is one of the most actively operating sites in Padang City, under the management of the Mina Gates cooperative, and is located in Gaung Market, Lubuk Begalung. Fish production at PPI Gaung comes from the catch of fishing boats that landed at the port: local fishing boats, bagan, tonda, and gillnet. There was a decrease in total fish production landed by 911.42 tons, or a decrease of 33.95% in 2021-2022. This study aims to determine what factors affect the production of catches. The research method used is the survey method, which involves making direct observations in the field and obtaining primary data from interviews with boat-bagan fishermen and secondary data from the port. The results of multiple regression analysis show that all factors have an effect. Six factors have a positive effect, and two have a negative effect. The most influential factor is the length of the trip/sea. The coefficient of determination (R2 ) is 0.757 or 75.7%. The coefficient of determination (R2) of 75.7% means that the presentation of the influence of the independent variables used in the model has an influence of 75.7% on the dependent variable, and the remaining 24.3% is influenced by other variables not included in the model. Other factors that are thought to have an influence include external factors such as the environment, weather, and existing technology. This study concludes that all factors affect the production of catches. Namely, 5 factors have a real influence: engine power, amount of fuel, area of fishing gear, number of lights, and length of trip/sea, while three factors do not significantly affect the size of the ship, the experience of the captain, and the number of crew

Abstract

Nemo (Amphiprion percula) are interesting ornamental fish living in anemones' tentacles. The body color of Nemo fish determines Nemo's selling price and the level of consumer demand. However, the fading of color in Nemo often occurs due to internal and external factors that can cause public interest and selling value to decrease. Therefore, it is necessary to research the addition of carrot, turmeric, and pumpkin solutions to Nemo to improve their color. This study aims to increase the brightness of the color in Nemo. The research method was carried out using an experimental method using a Completely Randomized Design (CRD) of four treatments and four replications so that 16 experiments were obtained. The study's results stated that adding Carrot, Turmeric, and Pumpkin solutions to Nemo fish did not affect increasing the brightness of the color in Nemo because the F Count obtained <from F Table 5% and 1%. This study emphasizes the importance of taking longer to soak active ingredient solutions such as carrot, turmeric, and pumpkin to obtain maximum results

Abstract

The research was conducted from January 01 to January 31, 2024, at the UPTD PPW II PPI Air Bangis, Pasaman Barat, West Sumatra Province. This study aimed to determine the target catch using the boat lift net fishing gear on the KM.NF vessel at the UPTD PPW II PPI Air Bangis Pasaman and to analyze the catch on Pini and Mentawai islands using the boat lift net fishing gear on the KM.NF vessel at the UPTD PPW II PPI Air Bangis Pasaman. The method used in this research was a survey method, which was analyzed descriptively. This boat lift net fishing gear utilizes light as a tool to attract the attention of fish, inviting them to approach the gear or enter the desired catch area, known as the catchable area. The boat lift net can be categorized into lifting nets based on its operational method. The use of light as an aid in boat lift nets continues to evolve, with variations ranging from stationary to floating boat lift nets. The fishing grounds for boat lift net vessels are located around the Mentawai and Pini islands, approximately 70 miles from the waters, with a depth of about 50 m. Fishing activities occur during the tide's ebb and flow at night. The process of retrieving the catch is done when the speed of the ebb or flow begins to weaken, ensuring more conducive conditions for fishing operations. The use of fishing gear is not

Abstract

With 72.56 km of coastline, Air Bangis is one of the largest fish producers in West Pasaman. West Sumatra has a vast marine area with hundreds of islands running north to south. At PPI Air Bangis, drift gillnets are used in the Pangkalan and Pini areas. Pangkalan Island is about 7 miles away, and Pini Island is 60 miles away. The fishing grounds greatly influence the amount of catch, what variables affect the catch in different fishing grounds, and what types of catch are caught in different fishing grounds. The method used was direct interviews in the fishing waters to classify the types of species and count the number of species caught by the drift gillnet gear. Fishermen were also interviewed to determine the standard main and bycatch. These results were analyzed using descriptive statistical analysis and tabulated in tables and graphs. Overall, the number of species caught by drift gillnet gear. Site distance, vessel capacity, and water conditions greatly influenced the effectiveness of the fishing grounds. In 6 GT vessels, the highest main catch was 58%, and the highest bycatch was 42%. On 3 GT vessels, the highest main catch was 57%, and bycatch was 43%. To maximize fish catch, proper and planned selection of fishing sites is essential while considering external factors such as selectivity of fishing gear used and weather conditions. Thus, tools such as echosounder can greatly help fishermen locate where fish congregate
