Abstract

                                                                  AbstrakBelut sawah (Monopterus albus) merupakan komoditas ikan air tawar yang sangat potensial dibudidayakan saat ini. Belut sawah mempunyai kandungan kolesterol yang cukup tinggi yaitu sebesar 185mg/10gram. Batas kolesterol normal yang dibutuhkan tubuh adalah 160-200 mg per hari. Kandungan kolestrol yang tinggi tidak sebanding dengan kandungan asam lemak tak jenuh daging belut sawah. Kandungan asam lemak tak jenuh pada daging belut sawah sangat kecil yakni α-linolenat acid sebesar 0,46%, EPA sebesar 0,22%, DHA sebesar 2,12%, Linolenat acid sebesar 7,42% dan Arakidonoit acid sebesar 1,75%. Salah satu upaya yang dapat dilakukan untuk menigkatkan Omega-3 dan Omega-6 adalah melalui rekayasa pakan, dengan penambahan suplementasi asam lemak yang berasal dari dari organisme laut yang diharapkan kandungan Omega-3 dan Omega-6 dapat meningkat di daging belut sawah. Penelitian ini bertujuan untuk meningkatkan kandungan Omega-3 dan Omega-6 daging belut sawah. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak lengkap yang terdiri dari lima perlakuan, empat kali ulangan. Analisis data menggunakan uji statistik sidik ragam Analysis of Variant (ANOVA) untuk mengetahui pengaruh perlakuan. Apabila ada perbedaan antar perlakuan dilanjutkan dengan Uji Jarak Berganda Duncan untuk mengetahui perlakuan yang paling baik. Hasil penelitian penambahan minyak ikan lemuru pada pakan komersial menunjukkan perbedaan yang nyata (P<0,05) terhadap kandungan Omega-3 (α-linolenat acid, EPA ,dan DHA) dan kandungan Omega-6 (Linoleat acid dan arakhidonat acid) daging belut sawah. Pemberian minyak ikan lemuru pada dosis 6% dapat meningkatkan kandungan (Omega-3) daging belut sawah α-linolenat acid sebesar 2,75%, EPA sebesar 2,87% dan DHA sebesar 1,29%. Pada dosis 6% minyak ikan lemuru dapat meningkatkan kandungan arakhidonoit acid sebesar 3,77% dan pada dosis 8% dapat meningkatkan kandungan Linoleat acid 4,24% daging belut sawah.                                                                 AbstractEel (Monopterus albus) are mostly bream a potential cultivated currently. Eel has a high cholesterol a month 185mg/10gram. Limit of the normal body needs cholesterol is 160-200 mg per day. The content of high cholesterol are not comparable with the content of unsaturated fatty acids eel meat. The unsaturated fatty acid on meat eel very low at α-linolenat acid of 0,46%, EPA of 0,22%, DHA of 2,12%, Linolenat acid of 7,42% and Arakidonoit acid of 1,75%. One effort can be done to increase omega-3 and omega-6 is through engineering feed, with the addition of supplements fatty acids that originated from marine organisms are expected to Omega-3 content and Omega-6 can increase in the meat eel. Research is aimed to increase Omega-3 content and Omega-6 flesh of eel. This research uses experimental methods to a draft random complete consisting of five treatment, four times remedial. Analysis data using statistical tests fingerprint variety of analysis of variant (ANOVA) to know the influence of treatment. If there are the differences between treatment continued by test distance multiple Duncan to know the best treatment. Research results in additional fish oil lemuru on commercial feed showing significant differences (p<0,05) against the omega-3 (α-linolenat acid, EPA and DHA) and the omega-6 (linoleic acid and arakhidonat acid) of eel. The doses 6% lemuru fish oil can improve the (Omega-3) of eel α-linolenat acid of 2,75%, EPA of 2,87% and DHA 1,29%. On the content doses 6% fish oil lemuru can improve Arachidonic acid of 3,77% and on content doses, 8 % can improve linoleic acid of 4,24 % meat eel.

Abstract

Abstract Blood cockles (Anadara antiquata, Anadara granosa) and Ark clams (Trisidos tortuosa) is one type of clams that is often consumed by people in Surabaya and Sidoarjo. The study was conducted in February-April 2014. The ratio of N/P on water conditions in Sedati of 3.3 / 1 it's indicates that the sampling process is done in the rainy season which resulted in the case of stirring the sediment. On the condition of the ratio N/P is phytoplankton still able to grow optimally. While the study site in Kenjeran, Surabaya obtained ratio N/P by 5.56 / 1 this indicates the potential of phytoplankton at this location is more optimal than the region in Sedati. In morphology, clams from Kenjeran is relatively larger than the clams from Sedati.

Abstract

Abstract The increase in value-added of fishery products is one of which can be done by processing. In addition to maintaining the value of the protein in the fish raw material, it would be easier if the product is stored and increase the sale value of the fish itself. The ability to perform in the fish processing in Mandangin island is still very limited. Community service activities that have been carried out by a team of the Faculty of Fisheries and Marine Universitas Airlangga was introduce smoked fish product processing with liquid smoke,because this method easier and faster so that the products can be marketed. Liquid smoke was developed because the location is very minimal in the supply of raw materials such as firewood and coconut, so the use of liquid smoke is very appropriate. The resulting refined products are expected to be a source of protein Mandangin Island community itself and is able to become an alternative source of income for the community to increase the sale value of fishery products. Mentoring process being conducted by a team from the Faculty of Fisheries and Marine Universitas Airlangga so that the products can be marketed outside Mandangin Island or even to other areas in East Java.

Abstract

Abstract Most organic materials utilized mangrove detritus such as mangrove leaves fall throughout the year. Organic particles or litter into a place to live for bacteria, fungi and other microorganisms. One of organic compounds in the soil is cellulose. Deciduous leaves on the ground allows that the cellulose content in the soil is high, it is possible to find cellulose degrading bacteria in the mangrove ecosystem. Soil sampling conducted in April 2014 located in Gunung Anyar Surabaya estuaries and Bancaran Bangkalan estuaries. After taking the samples, the isolation of cellulolytic bacteria and bacteria calculation were conduct using standard Total Plate Count (TPC). Based on the results of the calculation of total number bacteria, obtained the highest total number of cellulolytic bacteria at station E (Bancaran) of 4.9 x 104 CFU/ml. The highest percentage of cellulolytic bacteria obtained at station D (Bancaran) with a percentage of 27.09%. According to the whole calculation of the total number of bacteria, total number and percentage of cellulolytic bacteria, it was found that the area of Bancaran Bangkalan has higher abundance of cellulolytic bacteria than Gunung Anyar Surabaya mangrove areas.

Abstract

Abstract Tubifex tubifex is one kind of natural food for fish larva. This worm has an important role because it can support the fish growth faster than another natural food like Daphnia sp. or Moina sp. It is caused by its has high nutrition. Dry chicken manure can be used for manuring worm media because it have high organic matter. The purpose of this research was to know the effect of remanuring dry chicken manure to the population of Tubifex tubifex and to know the remanuring of dry chicken manure which is gives high population of Tubifex tubifex. The method used was experimental method. Completely Randomize Design was used in this research with 4 dose manuring treatments and 4 replication : PI (dose 0,08 g/cm2/l days), P2 (dose 0,4 g/cm2/5 days), P3 (dose 0,8 g/cm2/10 days) dan P4 (dose 1,2 g/cm2/15 days). The analysis result showed that the treatment of PI (dose 0,08 g/cm2/l day), manuring of dry chicken manure could give the highest population of Tubifex tubifex was 505 individuals reached at days20. At days-30 there was decreasing total number population so that the harvesting of Tubifex tubifex could be done at days-20. The water quality during this research were pH 6,4 - 7; DO 1,2 - 3,8 mg/1; water temperature 28 - 30 °C and ammonia 0,06 mg/1. The water quality was in optimum condition for Tubifex tubifex growth.

Abstract

Graphical Abstract   Highlight Research  Sustainable Management: Developing strategies for the long-term sustainability of shellfish resources in Sedati, Sidoarjo. Eco-Biological Considerations: Emphasizing the role of ecological and biological factors in managing shellfish populations. Socio-Economic Integration: Balancing economic activities and community welfare with the preservation of shellfish resources. Regional Focus: Tailoring management practices specifically to the unique environmental and social conditions of Sedati, Sidoarjo.     Abstract Sedati is one of the subdistricts producing fishery products, namely milkfish, shrimp, and shellfish. Some of the products are further processed generate long-term income. Economic variables profoundly influence shellfish harvesting, as heightened catches immediately enhance fishermen's revenue. Nonetheless, increased income may lead to intensified fishing activities, potentially jeopardizing the viability of shellfish populations if not adequately regulated. This study develop to the framework for sustainable management of shellfish resources based on eco-biology and socio-economic conditions. This research used a survey research method with primary and secondary data. The samples collected from this study were spread across 224 respondents who are fishermen. The hauling process is carried out while catching shellfish 100-150 times. Shellfish fishing activities are carried out 20–26 days a month. This study found that catch factors having no significant effect on sustainable fisheries management, ecological factors and shellfish capture and sustainable fisheries and sustainable fisheries management social factors and the capture of shellfish. Biological factors and shellfish catchment and management economic factors influence the shellfish capture showed significant influence on the fisheries management. The development of this model can serve as a benchmark for shellfish fishing activity in this coastal water. Overfishing or activities in this area can be monitored using this model. The purpose is to control or monitor the stock and the inventory of the shellfish fisheries to preserve them for further use. Economic factors have a significant effect on shellfish caching because the more shellfish caught, the income of shellfish fishermen will directly increase, economic factors also have a significant influence on the sustainable management of shellfish. The greater the income of fishermen, the greater the availability of shellfish stocks will be because the fishing effort carried out by fishermen will be massive. This research in the future can provide information on how to balance ecological, economic, and social factors to ensure the long-term viability of shellfish populations and the ecosystem support.
