Abstract

Extremophilic fish require genetic characterization to determine the identity of their species, their kinship, and the potential for genetic variation due to extreme environmental adaptation. DNA barcoding using Fish-F2 and Fish-R2 primers at an annealing temperature of 52oC for 15 seconds showed qualitative failure results in most fish species. For this reason, optimizing the annealing temperature in the PCR process is necessary to obtain DNA bands that correlate with successful identification. Fish samples were obtained from Ruai Silip, Bangka Island, Membalong, Belitung Island, and Way Kanan, Lampung, Sumatra Island. The annealing temperature optimization was set at 50, 50.4, 51.1, 52.3, 53.7, 54.8, 55.5, and 56°C. Five species of extremophile fish were tested, namely Brevibora sp, Barbodes binotatus, Rasbora bankanensis, Anabas testudineus, and Aplocheilus panchax. Extremophile fish showed differences in the appearance of DNA bands in PCR with different annealing temperatures. Brevibora sp showed a visualization of DNA bands at 54.8°C, Barbodes binotatus at 53.7, 54.8, 55.5, and 56°C, Anabas testudineus at 50 and 50.4°C, and Aplocheilus panchax produced clearly visible band on annealing temperatures.

Abstract

The Selincah fish (Belontia hasselti) is a local Indonesian fish that is widely consumed and has the potential to become ornamental fish. This fish must be domesticated to suppress its exploitation from natural catches. The domestication process requires biological information including eating habits. For this reason, in this study, the identification of phytoplankton contained in the stomach contents of the agile fish was carried out. Fish samples were obtained from Rawa Metukul, South Bangka Regency. The types of phytoplankton in the stomach and intestines of lively fish are the classes Bacillariophyceae, Chlorophyceae, Cyanophyceae, Chlorophyceae, Chrysophyceae, Chrysophyceae. The most dominant species were found in the Chlorophyceae class with an Index of preponderance value of 42.42%, while the Chrystophyceae class was found at least 2.99%.

Abstract

Grouper production in Indonesia can be supported by hybridization technology which can produce grouper species with relatively faster growth and more resistance to disease. Cantang grouper is a type of grouper fish that was engineered by crossbreeding between female tiger grouper (Epinephelus fuscoguttatus) and male grouper Kertang (Epinephelus lanceolatus). The purpose of this study was to determine the stages and technology of nursery grouper Cantang which was carried out at BPBAP Situbondo. The method used in this research is the method of observation, participation, and interviews. The primary data needed in this study are data on infrastructure, data on the number and size of seeds, feed management, water quality management, and harvesting. The data is presented with a descriptive method by discussing the data that has been obtained compared to the theories that have developed at this time. The results of this study indicate that cantang grouper nursery activities start from tank preparation, water filling, seed selection and distribution, feed management, water quality, fish pest and disease control, grading, and harvesting of cantang grouper seeds. During the practice period, the seeds were spread from hatcheries with a stocking density of 3000 to 5000 individuals in one tank with a size of 4 x 2.5 x 1 m, or the equivalent of 300 to 500 individuals/m3. The distribution of seeds is carried out after the acclimatization process, namely the adaptation process before releasing the seeds. After the seeds are removed, the tub is given an antiseptic to prevent disease in the seeds. There are several factors that can affect the growth rate of seeds, namely water quality management and feeding. During the maintenance period, a flowing water system is used, so that the water used is continuously renewed. In the morning, the seeds are flushed and soaked using fresh water, with the aim of releasing mucus on the seeds so as to reduce the potential for disease outbreaks. Nursery grouper at BPBAP Situbondo can run optimally by paying attention to the stages of cultivation, especially in the feed management and water quality management.

Abstract

Blue swimming crab is a fishery product with high economic value in Indonesia. Betahwalang Village, Demak, is one of the crab fisheries locations in the province of Central Java. High selling prices and processing industry demand encourages fishing activities. One issue brought on by increased fishing activity is the smaller crab size. It will impact the crab fishing industry in Betahwalang. The majority of the fisherman in Betahwalang Village catch crabs using arad nets, simple gill nets, and traps. This study aims to evaluate the size of crab catch results on fishing gear used by fishermen and recommend proper fishing gear for catching crabs. This research was conducted in April 2019. The catch size of crab was the primary data collected for this study, also with data on fishing grounds, methods, and characteristics of fishing gear. Data were collected by observation, interviews, and measurements of fishing gear and the carapace width of the crab. The results of data collection and processing were analyzed descriptively. The results showed that the highest proportion of legal size crabs (carapace width ≥10 cm) was caught in traps, while the proportion of unlegal size crabs caught was mostly in bottom gillnets and mini trawl.

Abstract

Green mussels (Perna viridis) in Banyu Urip Village, Ujung Pangkah Gresik District, have great potential to be developed due to the abundant availability of seeds in nature, easy cultivation methods, namely using floating net cages and step nets, and high market demand. One of the issues with green mussels is the high content of the heavy metal Lead (Pb) in their flesh, which is caused by heavy metal accumulation in the waters. The goal of this study was to isolate, characterize, and test the ability of heavy metal Lead-Pb bacteria to biosorb heavy metal Pb in post-harvest green mussels from sediments and green mussels in the Banyu urip Ujung Pangkah Gresik Sea. The stages of the research included sampling, isolation, macroscopic and microscopic characterization, in vitro testing of Pb heavy metal absorbent. The results showed 6 bacterial isolates, namely two from green mussels coded K1 and K2 and 4 bacterial isolates from marine sediments coded S1, S2, S3 and S4. The six bacterial isolates obtained macroscopic and microscopic characteristics and have been shown in vitro to be able to grow in Nutrient agar enriched 0.8 mg/L Pb(NO3)2.
