Abstract

The high price of fish meal is also a reason for alternatives and better protein sources. This research aims to substitute fish meal with maggot meal in feed for snakehead fish's growth rate and survival. The method used in this research is the experimental method of Completely Randomized Design (CRD), which consists of five treatments and three replications. The treatments used were (A) without the use of maggot flour (control), (B) 15% maggot flour substitution, (C) 30% maggot flour substitution, (D) 45% maggot flour substitution, (E) 60% maggot flour substitution, which was maintained for 50 days. The test fish used were snakehead fish with a 9-10 cm length and weighing 7-9 g. The container used is an aquarium with dimensions of 40x26x28 cm3 or a water volume of 15 L, in which five snakehead fish are placed in each aquarium. The amount of feed given is 5% of the fish biomass. The results obtained during the research showed that treatment E with the substitution of fishmeal for maggot meal at 60% of the feed resulted in the highest absolute length growth of 4.0 cm, the highest specific growth rate of 2.54%, and survival of 87%.

Abstract

Spirulina sp is one of the organisms used because it has twice the chlorophyll content of the alfalfa plant, the chlorophyll of which has previously been explored. Chlorophyll-a is a photosynthetic pigment, and light is very influential in photosynthesis in microalgae cultivation because light is a crucial part of the photosynthetic pigment as a source of energy for microalgae life. The purpose of this research is to get the best light intensity. This research started in September 2022 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau. This study used a one-factor, Completely Randomized Design (CRD) method with five treatments and three replications. The treatment in this study was the light intensity consisting of P0: without giving light, P1: 2.974 lux, P2: 4.274 lux, P3: 5.575 lux, P4: 6.877 lux. The results of this study indicate that light intensity affects the locking of Spirulina sp. The best treatment was a light intensity of 4.274 lux with a cell density of 327.176,2 ind/mL with a chlorophyll-a content of 0.4 µg/mL with a range of water quality parameters that were optimal for the growth of Spirulina sp temperature value 28-31, pH 7-8.5, DO 5-7.5.

Abstract

Water quality is a condition of water based on physical, chemical, and biological properties that suit the needs of aquatic organisms and humans, such as water quality in fisheries, agriculture, drinking water, hospitals, and industry. This research aims to analyze the feasibility of water quality parameters for mangrove waters in AekHorsik village, Tapanuli Tengah Regency, as a location for developing fisheries cultivation. The research method used is a descriptive method with quantitative data analysis. The results of this research show that the chemical parameters obtained were pH (7.3-7.9 ppt), salinity (12-22 ppt), ammonia (0.25-0.29 mg/L), and DO (5.0-55 ppm). The physical parameters obtained are temperature (30-32oC), brightness (0.53-0.95 m), current speed (0.05-0.08 m/sec), and depth (0.53-0.95 m). The biological parameters obtained were phytoplankton abundance of 3,400-6,100 14,450 ind/L and macrozobenthos abundance of 104.9-179.0 ind/m2. Based on these results, it can be seen that the water quality parameters of mangrove waters in AekHorsik village, Tapanuli Tengah Regency, are suitable as a location for developing fisheries cultivation.

Abstract

Bubu is a passive fishing tool that works by trapping. Over time, a modification known as the bubu payung emerged, which is easy to obtain at an affordable price. This research was conducted in November 2023 over ten days in the waters of the Parit 18 River in Sapat Village, Kuala Indragiri District, Indragiri Hilir Regency. The method used in this research was experimental fishing, employing three types of bait: malong, coconut cake, and coconut pulp. Data analysis was performed using the t-test with SPSS 27.0.1. The results showed no significant difference in the catch of malong bait, coconut cake, or coconut dregs. According to the calculations, bait comparison A t-value (malong bait and coconut cake) (0,294) < t-table (2,306), bait comparison B (malong bait and coconut dregs) t-value (0,385) <t-table (2,306), and bait comparison C (coconut cake bait and coconut dregs bait) t-value (0,081) <t-table (2,306). Therefore, bubu payung can effectively catch mangrove crabs and bycatch.

Abstract

As much as 90% of the fisheries industry in Dumai City comes from capture fisheries. The capture fisheries industry is a crucial industry that requires more attention from the government because of its enormous potential. Every year, there is a decrease in the number of fishing households in Dumai City. The reason is the uncertainty of income received and the existence of other business sectors. Fishing communities depend on fisheries resources for their livelihoods. However, the fishing profession in Dumai City is susceptible to changes around it, including changes due to the development of the CPO industry. This study was conducted to analyze the economic impact of the CPO Industry's development on the Lubuk Gaung Village fishing community. This research uses a quantitative survey method, followed by quantitative descriptive data analysis and hypothesis testing with a paired sample t-test. The fishing community in Lubuk Gaung Village felt the economic impact of various indicators. Total household income experienced a significant increase of IDR 2,452,880. Total household expenditure also experienced a significant increase, amounting to IDR 1,185,800. Meanwhile, in terms of asset ownership, fishermen have experienced an increase in asset ownership to meet their daily needs since the existence of the CPO Industry.

Abstract

Hangtuah Village is known as "Kampung Lele"; one of the business actors who run the catfish processing business is the Mina Sejahtera Group. This research was conducted in October 2023 in Hangtuah Village, Perhentian Raja District, Kampar Regency, Riau Province. This research aims to identify the supply chain pattern for catfish crackers and analyze the added value of catfish crackers in the Mina Sejahtera Group. The research method uses a survey method, and data is analyzed qualitatively and quantitatively. The research results show that the supply chain actors consist of partner farmers as suppliers of raw materials for catfish, the Mina Sejahtera Group as business actors and processors of catfish crackers, and consumers as buyers. Supply chain flows include product flows, financial flows, and information flows. The condition of the supply chain for catfish crackers in Hangtuah Village is based on the Food Supply Chain Network (FSCN) approach, which is seen from the supply chain targets, supply chain structure, supply chain entities, supply chain management, supply chain resources, and supply chain business processes that have been integrated with Good. The added value of processing catfish crackers is IDR 11.600/kg with a value-added ratio of 45,3%. The average profit given in the catfish processing process is IDR 5.600/kg or 48,2% of the product's added value, meaning that every kilogram of fresh catfish raw material processed can provide a profit of IDR 5,600/kg in added value.

Abstract

Fish resources have limits; therefore, it is necessary to carry out appropriate management so that resource utilization is sufficient for a long time. Areas used as fishing businesses need to know how the level of utilization. For this reason, clear information is needed on the potential and level of utilization of marine fisheries resources to support the management policy of tuna resources for optimal management and utilization and to prevent the reduction of fish stocks in the future. This research was conducted for three weeks in July 2023 at Bungus Ocean Fishing Port (PPS), Padang City, West Sumatra Province. The method used in this research is a survey method or direct review of the field. The maximum sustainable potential value was obtained at 572.36 tons with an optimum utilization effort value of 330 trips. The allowable catch of longtail tuna is 457.89 tons, with an average utilization rate of 97.41%. Based on the average value of the utilization rate obtained from 2018 to 2019, the number of allowable catches, and the MSY value, it is concluded that the longtail tuna caught by bagan boats and Tonda fishing rods at PPS Bungus has experienced overfishing. There is a need for more action and monitoring of the amount of catch obtained each year, as well as limiting the amount of catch allowed for each fisherman so that the utilization rate of longtail tuna can return to optimal catch and prevent overfishing and maintain fish stocks for the future.
