Abstract

Rasbora galaxy (Danio margaritatus) is a type of freshwater ornamental fish that has a high economic value and is in great demand in the international market. This fish is included in the omnivorous animal group and can consume natural feed and commercial feed. Commercial feed has the advantage of being able to be designed with a nutritional formulation according to the needs of the type and age of the fish. Among the important factors in feeding management is the dose of feed. Feeding with low or high doses both have a negative effect on the absolute length growth of rasbora galaxy fish. The purpose of this study was to determine the effect of providing commercial feed with different doses on the absolute length growth of rasbora galaxy fish (Danio margaritatus) measuring 1.5-2 cm in experimental tanks. This study used an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications. The treatment in this study was the provision of commercial feed with different doses. Treatment A; 2% of the weight of the test animal biomass, treatment B; 3% of the weight of the test animal biomass, treatment C; 4% of the weight of the biomass of the test animals, treatment D; 5% of the weight of the biomass of the test animals and treatment E; 6% of the weight of the biomass of the test animals. The test animals used 1.5-2 cm galaxy rasbora fish with an average weight of 0.5 g/tail. The stocking density was 2 fish/liter, the experimental media used fresh water with a volume of 3 liters/tub. The results showed that treatment C gave the best results for the absolute length growth galaxy rasbora fish of 0.74 cm/tail. Water quality data obtained water temperature ranged from 26.8 - 27.8 0C, acidity levels ranged from 6.9 - 7.1 and dissolved oxygen ranged from 5.29-5.69 ppm.

Abstract

This study aims to analyze marketing channels, marketing margins, shrimp farmer's share, marketing costs, profit-to-cost ratio, and marketing efficiency for black tiger shrimp (Penaeus monodon) and vaname shrimp (Litopenaeus vannamei) in Sepatin Village, Anggana District, Kutai Kartanegara Regency. The sampling method used purposive sampling and snowball sampling, involving 40 farmer respondents and 2 marketing institutions. The results show two marketing channel patterns: one-level channels (Producer-Collector-End Trader) and two-level channels (Producer-Collector-Retailer-Consumer). The marketing margins for black tiger shrimp and vaname shrimp in the level one channel were Rp 4,600/kg and Rp 6,500/kg, respectively, while the level two channel reached Rp 10,000/kg. The shrimp farmer's share for level one was 97% for black tiger shrimp and 92% for vaname shrimp, whereas level two was only 2%. Marketing efficiency for level one ranged from 1% to 2%, while level two reached 3% and 38,7%. These findings demonstrate that the level one marketing channel is more efficient than level two. Keywords: Marketing Channel, Marketing Margin, Marketing Efficiency of Tiger Shrimp and Vaname Shrimp.

Abstract

Bandotan leaves have the potential to be used as a natural anaesthetic for fish transportation. The objective of this study was to determine the effectiveness and optimal concentration of bandotan leaf extract (Ageratum conyzoides L.) on the survival of tilapia during wet transportation. This study employed a completely randomised design (CRD) with four treatments of bandotan leaf extract: P0 (Control), P1 (250 mg/3L), P2 (300 mg/3L), and P3 (350 mg/3L), each repeated three times. The test subjects were tilapia fingerlings transported in a wet transport system for 6 hours. The optimal dose of bendotan leaf extract was found to be P1 (250 mg/3L) with an induction time of 40 minutes, a recovery time of 5.5 hours, and a survival rate (SR) of 98.04±3.39%. Water quality during transport was within tolerable conditions for tilapia, with temperature ranging from 26–27.2 °C, pH from 7.43–7.66, and dissolved oxygen (DO) from 0.7–1.2 mg/L.

Abstract

As a country with a very high level of fish consumption, Japan relies heavily on the marine sector, especially in the activity of catching abundant marine products. Various types of fishing gear have been developed, ranging from traditional equipment to modern technology using machines and robots. These efforts are made by the Japanese government to ensure the availability of fresh fish for its people. This study aims to compare fish catches based on different colors of artificial bait and to identify and analyze the effect of bait color on the effectiveness of catches directly in the field. The research material focuses on the comparison of artificial bait colors to improve the catch of the pole and line method. The method used in this research is descriptive qualitative. The results showed that silver-colored bait was most effective in attracting skipjack, with the highest number of catches compared to the other two bait colors. In addition, catches were recorded significantly higher in the morning session (07:00-11:00) compared to the afternoon and evening sessions. The fishing location factor also contributed to the variation in catch, with some locations showing higher levels of productivity. These findings confirm the importance of choosing the right time, location and bait color to optimize catch using the pole and line method.

Abstract

Penelitian ini bertujuan untuk mengevaluasi respon makan udang vaname pada stadi post larva (PL 20) dengan pemberian pakan alami jenis maggot. Penelitian ini bersifat eksploratif dengan metode experimental laboratoris. Perlakuan yang dilakukan terdiri dari 1 jenis perlakuan yaitu pemberian maggot dengan dosis 20% dari bobot badan per hari (20% / BB / Hari), yang diberikan sebanyak 3 kali sehari. Penelitian dilakukan dengan 10 kali ulangan. Data penelitian dianalisis secara deskriptif. Hasil penilitian menunjukkan bahwa respon udang vanname sangat baik terhadap pemberian maggot, yang dapat dilihat dari beberapa indikator yaitu (1) Respon udang vanname PL 20 mampu menerima maggot dengan baik sejak awal pemberian, (2) Respon kaki jalan (pereopod), pada hari ke 3 udang menunjukkan peningkatan aktivitas membawa maggot menggunakan kaki jalan jika dibandingkan hari sebelumnya, (3) Respon perilaku makan, pada hari pertama udang vanname belum cepat merespon maggot. Namun pada hari-hari berikutnya udang vanname menunjukkan gerakan cepat mendekati pakan maggot, (4) Kualitas air selama penelitian masih berada dalam kisaran yang layak untuk kehidupan udang vanname yaitu suhu memiliki nilai berkisar 29-30 °C, DO (Dissolved Oxygen) memiliki nilai berkisar 5.3-6.5 mg/L, Salinitas memiliki nilai berkisar 31 ppt, pH memiliki nilai berkisar 7.9-8.0 dan Amonia (NH3) memiliki nilai berkisar 0.2-2.0 mg/L. Dengan demikian, maggot berpotensi digunakan sebagai alternatif pakan alami untuk udang vaname pada stadia PL 20 terutama dalam tahap adaptasi pakan awal.
