Abstract

Biofloc technology (BFT) is one of the most developed aquaculture technologies, which aims to improve the efficiency of feed use by providing nutrients for flocs to be used by fish as a supplementary feed. Also, BFT serves to improve water quality through the breaking down of fish waste materials assisted by heterotrophic bacteria. Bacteria used in this study were Bacillus sp. as probiotics in BFT. This study aimed to examine the production performance of catfish maintained with a biofloc system on an industrial scale, without experimental design. The average weight of catfish when stocking was 5.9 ± 0.0 g/fish with a density of 7000 fish in 9 unit circular ponds. This studies showed after 78 days of culture, bodyweight gain about 28.6 g/fish to 41.7 g/fish, highest specific growth rate was K2 (2.4 ± 0.2% BW/day), the highest survival rate K2 (98.87 ± 6.64% BW/day), highest grow rate K1 (41.7 ± 5.8 g) and the best FCR K9 (0.95 ± 0.11).

Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the leading fishery commodities that have high economic value. If the process is implemented properly, shrimp production with a super intensive system becomes a profitable future of the aquaculture orientation. This study aims to examine the production process and product performance of super- intensive system vannamei shrimp on an industrial scale. This research method is a case study that includes observation, interviews, and directly follows the production process of shrimp on an industrial scale, without experimental design. The production process includes ponds preparation, media preparation, seed selection and stocking, management of feed and water quality, monitoring of pests and disease, monitoring of growth, and harvest. The treatment given was the application of Bacillus sp. as probiotics on rearing media to optimize shrimp growth. This study showed after 100 days of rearing resulted in SR 71%; biomass 8.96 tons; harvest size 45 – 32; ABW 22 g/tail; ADG 0.4 g/day; and FCR 1.6. Water quality was still in the optimal ranges to support of shrimp growth, includes: temperatures 27 – 31oC; brightness 14 – 120 cm; pH 7.4 – 8.6; salinity 33 – 34 mg/L; dissolved oxygen 3.8 – 5.5 mg/L; alkalinity 100 – 360 mg/L; TOM 40 – 103 mg/L; and nitrite 0.05 – 27.5 mg/L. The production process of vannamei shrimp on an industrial scale with a super intensive system that is applied by PT. Sumbawa Sukses Lestari Aquaculture, West Nusa Tenggara shows optimal growth and yields.

Abstract

Abstrak - Penelitian dilakukan untuk mengetahui pertumbuhan Kappaphycus striatum dibudidayakan dengan sistem tali rawai dan jaring kantong yang dibudidayakan selama 42 hari. Penelitian menggunakan dua perlakuan, yakni budidaya rumput laut dengan tali rawai dan jaring kantong dengan empat pengulangan. Desain yang digunakan dalam penelitian ini yaitu Randomize Pretest-Posttest Control Group Design yang kemudian dianalisis dengan Uji-t dua sampel. Laju pertumbuhan spesifik, pertumbuhan mutlak, dan pertumbuhan relatif Kappaphycus striatum pada sistem tali rawai masing-masing berkisar antara 2,52 ± 0,23 % per hari, 140,82 ± 19,46 gram, 91,7 ± 9,73 %, dan pada sistem jaring kantong masing-masing berkisar antara 3,58 ± 0,26 % per hari, 239,32 ± 21,95 gram dan 153,41 ± 10,97%. Nilai-nilai tersebut dipengaruhi oleh perubahan variabel kualitas air selama periode budidaya. Berdasarkan uji t, sistem tali rawai dan jaring kantong secara signifikan berbeda nyata (p < 0,05) satu sama lain. Kondisi parameter kualitas air suhu, pH, oksigen terlarut, kecepatan arus dan kedalaman sesuai dengan standar yang ditetapkan, sebaliknya pada parameter salinitas, kecerahan, nitrat dan ortofosfat belum mendukung pertumbuhan optimal untuk budidaya Kappaphycus striatum. Namun secara keseluruhan disimpulkan bahwa penggunaan jaring kantong pada budidaya rumput laut Kappaphycus striatum memiliki pertumbuhan yang lebih baik dibandingkan dengan sistem tali rawai. Kata Kunci: Rumput Laut, Kappaphycus striatum, Jaring Kantong, Tali Rawai Abstract - The study was conducted to determine the growth of Kappaphycus striatum cultivated with a longline and bag net system which was cultivated for 42 days. The study used two treatments, namely seaweed cultivation with longlines and bag nets with empathy. The design used in this study was the Randomize Pretest-Posttest Control Group Design which was then analyzed by using a two-sample t-test. Specific growth rates, absolute growth, and relative growth of Kappaphycus striatum in the longline system ranged from 2.52 ± 0.23% day-1, 140.82 ± 19.46 g, 91.7 ± 9.73%, respectively. And in the bagged net system, respectively around 3.58 ± 0.26% day-1, 239.32 ± 21.95 g and 153.41 ± 10.97%. These values ​​are influenced by changes in air quality variables during the cultivation period. Based on the t-test, the longline system and bag nets were significantly different (p < 0.05) from each other. The parameters of air quality, pH, dissolved oxygen, current velocity, and depth were by the established standards, on the other hand, the parameters of salinity, brightness, nitrate, and orthophosphate did not support optimal growth for Kappaphycus striatum cultivation. But overall the key is that the use of bag nets in seaweed cultivation Kappaphycus striatum has better growth compared to the longline system.

Abstract

Farming seaweed is a significant source of income since it helps coastal communities become more resilient. Due to the simple growing, harvesting, and drying methods, low degree of capital investment, and quick production cycle (1.5 months), seaweed cultivation in Tablolong Village, West Kupang District, East Nusa Tenggara Province is dominated by cultivators from coastal villages. The present issue for farmers of seaweed is the unavailability of seeds, both in terms of quantity and quality. Simple actions such as community service projects (PKM) with a focus on fertilizing activities utilizing bionic fertilizers can be taken to encourage the growth of seaweed. The method used to achieve the target of this PKM program is participatory counseling, dissemination of research results, assistance in seaweed cultivation, and monitoring during seaweed cultivation. In November 2021, PKM operations are conducted in Tablolong Village's coastal region. Through the use of bionic seaweed fertilizer, the activity's aim is to earn the partner group's production rates. After participating in PKM activities, the "Blue Sea" partner group was able to produce Kappaphycus striatum by utilizing bionic fertilizers, where the analysis results showed that the daily growth rate was 3.38% day-1, absolute growth was 176 gr and production was 2,755.62 gr m-1.

Abstract

Litopenaeus vannamei shrimp is a leading fisheries commodity in Indonesia. It’s quite popular for cultivation related to strong attributes that include; fast growth, disease resistance, and high economic value. One of the successes of shrimp cultivation is greatly influenced by water quality. Water quality dynamics describes the occurrence of fluctuations in water quality in the media, which is an important factor that influences shrimp growth performance. This study aimed to evaluate the effect of water quality dynamics on the growth performance of vannamei shrimp in intensive ponds in CV. Daun Prima, East Java. The research method used is a case study which includes interviews, observation, and following all stages of the shrimp production process at CV. Daun Prima. The results showed optimal water quality, including temperatures of 27 – 31°C, brightness of 20 – 45 cm, pH of 7.5 – 8.1, dissolved oxygen of 4.50 – 5.33 mg/L, and salinity of 30 – 33 g/L. Growth performance of the shrimp produced, such as ABW of 3.55 – 15.33 grams/ind, ADG of 0.21 – 0.35 grams/day, and survival rate of 80%. Water quality dynamics in intensive ponds are stable during maintenance. Water quality parameters are within the optimal range to support the growth performance of shrimp. This study benefits shrimp farmers, industry stakeholders, and policymakers by identifying optimal water quality conditions that enhance growth performance and survival rates in vannamei shrimp farming.Keywords:  Dynamics, Growth Performance, Litopenaeus vannamei, Shrimp, Water Quality
