Abstract

Sea lobster is a commodity that has high value in both national and international markets. Globally, the demand for sea lobster is increasing by about 15% per year. During growth, lobsters undergo a moulting process. Moulting/ecdysis is a very important process in the life cycle of arthropods (including decapods) because shell release is a must for growth and metamorphosis. In improving and assisting the molting process in lobsters, it is assisted by the provision of additional calcium from egg shells. Egg shells contain 94% calcium carbonate, 1% calcium phosphate, 1% magnesium carbonate and 4% organic compounds. In this study, an experiment was conducted on the addition of feed with a mixture of egg shells to support post-moulting optimization and supplement calcium requirements for lobster larvae. The percentage of egg shells as treatment, namely treatment A (0%), B (5%), C (10%), and D (15%) of the total feed to be made for sea lobster. Maintenance is carried out in a controlled tub, for four months. The highest specific growth obtained in this treatment was treatment A (0.06-0.21%) and the lowest was treatment D (-0.02%)-(-0.37%). Furthermore, the highest survival rate was obtained in treatment A (66.7%) and the lowest in treatment D (33.3%), the highest number of molting lobsters was in treatment A (77.8%) and the lowest was treatment D (33.3%). This shows that the addition of eggshell flour to moist lobster feed has not had a significant effect. For further development, it is necessary to research related to the use of additional ingredients in moist feed for lobster.

Abstract

GMO is a product of biotechnology through genetic engineering techniques. This can be done to increase food availability and reduce production costs, especially by manipulating the genes and chromosomes of cultivated species. In invertebrates such as shrimp, the application of gene transfer is still limited to the recognition and expression of foreign genes and focuses on increasing disease resistance. Among several gene transfer methods (microinjection, electroporation and transfection), transfection method is the most effective method to be applied to shrimp. It is characterized by high hatching data and is not toxic. In addition, the use of GMO in aquaculture is a highly controversial issue due to many environmental and health issues. This journal will discuss gene manipulation by means of gene transfer to improve shrimp culture.

Abstract

The potential and development of alternative livelihoods for fishermen households in marine conservation areas must be relevant to or refer to the context of contextual technical considerations (locality), and not a deduction or bottom-up policies derivation so that they can grow and develop (facilitating) local fishermen's households in production activities that are complementary to increasing the spirit of the locality, community harmonious with natural resoureces and welfare through the opening of new economic spaces that can be accessed and controlled by the local community themselves. This type of research is qualitative with a case study approach. Data was collected through direct observation and in-depth interviews with some informants. There are 30 fisherman’s household which is used as primary data source informants. Qualitative analysis based on technical variables, namely community interest, availability of local raw materials/natural resources, availability of labor and market opportunities through content analysis from compilation of interview results through snowball technique with reference to triangulation principle. While quantitative data analysis is carried out with business feasibility indicators for new alternative types of livelihoods that can be applied to fishermen households, namely B/C Ratio indicators, Return Of Investment (ROI), and Payback Period (PP). Research result show that based on the analysis of technical variables, the potential alternative livelihoods carried out by fishermen households are seaweed aquaculture, floating net cage aquaculture, processed fishery products, coconut and household scale chicken and duck farming. The B/C ratio value of these businesses is > 1 with very profitable criteria to do.

Abstract

Indonesia has the potential for the beauty of its islands and coasts which are well known to foreign countries. Not only beautiful beaches, also stretches of coral reefs with hundreds of marine species, mangrove forests with their ecosystems are a panorama that can be found from Sabang to Maraoke. It is estimated that more than 21 marine tourism sites have been developed and become destinations for world and local tourists, in addition to locations that are still managed by the community. Foreign exchange contributions from the tourism sector continued to increase in 2018, the tourism sector's foreign exchange reached IDR 229.5 trillion, an increase of 15.4 percent on an annual basis. This study aims to describe the condition of marine tourism potential in South Sulawesi and its impact on local communities living around tourist sites and the development needed to improve the welfare of local communities. The research locations were on Lemo Beach, East Luwu Regency, Bira Bulukumba Beach and Makassar Lantebong Mangrove Tourism, taking 100 respondents. The research method is qualitative and analyzed descriptively by correlation and using Likers to assess its impact on people's welfare. The results of the study illustrate that in general, the role of the government, both local and provincial, is still needed, especially in environmental hygiene facilities, order for traders. The social impact on people's behavior shows that there is a change in the ability to communicate and interact more openly with a value of 1634. The economic impact shows a very large regional value due to the opening of new job opportunities which are a source of income for the local community with a value of 2250.

Abstract

The Covid-19 outbreak has had a serious impact on various aspects of life and so far no drugs and antivirals have been found to completely cure the outbreak. Covid-19 has also become a serious threat in the economic field, one of which is in the field of processing fishery products. This study aims to determine the resilience of MEMEs in processed fisheries before the pandemic and during the COVID-19 pandemic in Makassar City. The sample in this study were eight MSMEs processed fisheries in the city of Makassar which were selected by purposive sampling. Primary data collection was carried out by interview using the help of a questionnaire. The data that has been collected was analyzed using a qualitative descriptive method. The results of the study show that the adaptations or strategies adopted by MEMEs in processing fisheries in meeting their daily needs are grouped into three categories, namely: The first is an active strategy, namely carrying out various activities by self-employment. The second passive strategy is trying to avoid risks caused by non-economic shocks (e.g. reducing social costs, health, education, and surrendering to circumstances). Furthermore, the network strategy is for example establishing relationships to obtain assistance both informally and formally from other parties.

Abstract

Aquaculture is a growing fisheries sector. Along with the growth of aquaculture, water quality problems become one of the main factors that need to be considered, especially related to pollution pressure. Microplastic (MPs) is a pollutant sourced from anthropogenic activities and is currently in the spotlight and has been widely studied in aquatic environments around the world. However, in Indonesia, research related to MP especially in term of aquaculture activities is still lacking. The presence of MP in aquaculture activities can originate from internal sources such as the use of unmaintained aquaculture equipment/facilities and the use of feed contaminated with MP. Then, the external source of MP at the cultivation location can come from water sources that come from an environment that has been previously polluted by MP. Maintenance of aquaculture equipment/facilities, search for alternative feed raw microplastic free materials and protection of the aquatic environment from MPs are some of the ways to reduce the presence of MP in aquaculture sites. The existence of MP in aquaculture activities is related to food safety of aquaculture commodities.

Abstract

Tilapia is one type of freshwater fish that has economic value. This type of fish has good adaptability and fast growth. One of the problems in tilapia cultivation is that probiotics have not been utilized in the maintenance media with a biofloc system. This study aimed to determine the dose of probiotic supplementation in the formation of bioflocs on the growth and survival of tilapia. The research was conducted at the Educational Pond, Bosowa University, Maros Regency. The test animals used were tilapia seeds measuring 2-3 cm long. The stocking density of 3 seeds/L were kept in a basin with a capacity of 80 L filled with 60 L of water. The treatment tested was GDM probiotic supplementation in media with doses of A 5%, B 6%, C 7%, and D 0 %. The study used a completely randomized design with 4 treatments and 3 replications so that there were 12 experimental units. Seeds were reared for 60 days by feeding Hi-Pro-Vite FF-99 as much as 3% of body weight biomass per day. The results showed that GDM probiotic supplementation with different doses significantly affected the growth and survival of tilapia. Supplementation of GDM probiotics 5%, 6% and 7% in the media gave the same effect on the growth and survival of tilapia but significantly different from the treatment without probiotics. The highest growth and survival rate of tilapia was obtained at a dose of 5%, 4.27g and 65%, respectively, while the lowest was in the treatment without probiotics, namely 3.27g and 48.33%. Based on the results of the study, it is recommended that 5% GDM probiotic supplementation in tilapia rearing containers is recommended.

Abstract

One alternative to increase production is to maximize the use of biofloc system cultivation technology. However, the problems in biofloc cultivation are; the difficulty of cultivators to replace or alternatively use commercial bacteria to increase production. One of the efforts made is the use of bacillus sp. The aim of the study was to determine the optimal concentration of bacillus sp that could increase the growth of saline tilapia. This study used a completely randomized design (CRD) with four treatments, each repeated three times, so that there were 12 units. This study tested the concentration of Bacillus sp. 0.0028 ml/L, 0.0030 ml/L, 0.0032 ml/L, and 0.0034 ml/L. The results showed that the highest protein retention was 9.91%, fat retention was 2.05% and the body glycogen content of saline tilapia was 0.68%. This shows that the administration of Bacillus sp. in saline tilapia culture media has a real effect.

Abstract

This study aims to determine the growth rate of Salin tilapia (Oreochromis sp.) which is cultivated in a biofloc system using fermented vegetable waste feed. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications and the feed used was fermented vegetable waste with different doses of prebiotics, treatment A Control, B 30 ml/kg, C 40 ml/kg, and D 50 ml /kg. The results showed that the feeding of fermented vegetable waste had a significantly different effect (P<0.05) on the growth rate. Fermented vegetable waste feed with a probiotic dose of 30ml/kg showed a daily growth of 5.44% although the survival from the ANOVA test results showed no significant difference.
