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. Keywords : Seaweed, Kappaphycus striatum, Bag Net, Longline.

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

The spawning sites of Anguilla borneensis and Anguilla celebesensis were in the seas off Sulawesi and the Gulf of Tomini, the spawning sites of Anguilla marmorata and Anguilla bicolor pacifica were in the western part of the North Pacific. The purpose of this study was to find out information on the diversity of eel seeds and adult eels in the Dumoga River based on the abundance of eel seeds and gonad maturity of adult eels. The eel species consisted of 1,106 A. marmorata, A. bic. pacifica as many as 854 tails and Anguilla spp as many as 291 individuals. The caught eel fish were separated based on the morphology of the eel species. Segregation of catches based on special characteristics of eel, namely preanal and predorsal lengths. Anodorsal values were divided into three groups, namely ±15.57% (A. marmorata); ±1.18% (A. bicolor pacifica) and ±7.09% (Anguilla spp.). Meristic values of A. marmorata for spine (TB) total 104-106 units, pre-dorsal TB 17-19, pre-anal TB 36-39 and ano-dorsal TB 18-20. Meristic values of A. bicolor pacifica for spine (TB) totaled 108-112, pre-dorsal TB 32-36, pre-anal TB 32-39 and ano-dorsal TB 0-3. Meristic values of Anguilla spp for spinal (TB) totaled 100-106, pre-dorsal TB 27-29, pre-anal TB 30-33 and ano-dorsal TB 6-12. The growth pattern of adult eels is negative allometric, i.e. the body length gains faster than the slower body weight gain. The condition of adult eels in the Dumoga River is not fat because the condition factor ranges from 0.0024-0.0036. The average length of adult eels was 58.92cm in Anguilla marmorata (GIC 1.57–2.90%); 54.2cm in A. bicolor pacifica (ICI 1.27–2.79%) and 52.32cm in Anguilla spp (ICI 0.97-2.50%).

Abstract

Diseases arise due to unbalanced interactions, namely pathogens, hosts and the environment. This collapse will affect the increase or decrease in disease in fish. This research aims to identify parasites and analyze water quality in Carp Fish hatcheries. Carp seed samples were taken randomly in research containers. The water quality parameters observed consisted of temperature, pH, DO, nitrate, nitrite, and ammonia. This research was conducted for one month at the Tatelu Freshwater Aquaculture Center (BPBAT). The results of the research show that there are three types of parasites found in the gills, mucus, and fins of Carp Fish, namely Tricodina sp, Dactylogyrus sp, and Gyrodactylus sp.
