Abstract

Development of milkfish aquaculture in traditional ponds must of course be based on its potential. One of the most important potentials is the local knowledge of the community about the aquaculture system in ponds. The purpose of this research is to analyze the behavior and local knowledge of traditional farmers in managing their aquaculture business which is influenced by elements of local culture that penetrate into the social system of society. This type of research is qualitative with a case study approach. Data collection was carried out through direct observation and in-depth interviews with a number of informants. The process provides a comprehensive description of the actions and practices in managing traditional pond businesses. There were 27 informants as the primary data source. Analysis through content analysis from the compilation of interviews with technique snowball by still referring to the principle of triangulation. The results showed that local knowledge, method technology, and traditional aquaculture practices, farmers still did because they still were considered functional and effective. Modern aquaculture technologies have not been able to replace most of the main functions of these local practices. The effectiveness of function is shown through the recognition of farmers that with traditional technology, they can carry out their aquaculture business activities and obtain the main source of income from the past to the present.  Existing local knowledge is closely related to customary beliefs as norms that regulate social interactions.

Abstract

Polyculture is an aquaculture system that culture more than one species of fish in a single culture pond. The application of the concept of polyculture continues to develop rapidly and at its peak in the late 20th century, the application of integration in aquaculture activities resulted in a new polyculture system based on the integration of species with different trophic levels and having mutualistic relationships or better known as Integrated Multi-Trophic Aquaculture (IMTA ). Utilization of aquaculture waste from mainly species culture by secondary species is able to create an ecologically balanced aquaculture system, improve water quality, eliminate biological traces and provide better economic benefits compared to monoculture cultivation systems. Knowledge of trophic levels, feeding habits, placement of living space are things that must be mastered so that there is no competition between species that can cause failure in polyculture and IMTA activities. As developing science and public awareness of environmental quality generate demand for aquaculture activities can be more environmentally friendly and pay attention to aspects of sustainability of aquaculture activity. The Polyculture and IMTA systems are aquaculture systems that have the potential to be applied because they fulfill these two aspects.

Abstract

Nannochloropsis oculata is one of the single-celled microalgae that has been commonly cultured in the marine fish culture sector as zooplankton feed which has high nutritional content. To support growth and reproduction, the availability of nutrients in N. oculata culture media needs to be considered. This study aims to determine the effect of the best liquid organic fertilizer (POC) duckweed (L. minor) on cell population growth in N. oculata culture. The method used in this research is an experimental method using Completely Randomized Design (CRD) with 5 treatments, namely P0 (TSP 10 mg + ZA 40 mg + urea 45 mg) as a control treatment, P1 (POC duckweed 5%), P2 (POC duckweed 10%), P3 (POC duckweed 15%), and P4 (POC duckweed 20%) were repeated 3 times in each treatment. The initial density of N.oculata cells was 2 x 106 cells/ml in a culture media volume of 1000 ml. Growth was observed every day for 14 days. The results showed that the POC concentration of 10% duckweed can be used as an alternative to inorganic fertilizers (TSP, ZA, and urea) because it can increase cell population growth by 30.92 ± 1.84 cells/ml at the peak of the exponential phase, as well as the value of the growth rate. cells 0.38 ± 0.03 cells / ml / day and cell generation time of 43.88 ± 3.24 hours were not significantly different (p> 0.05) with P0 treatment (TSP, ZA, and urea). The range of water quality parameters in the culture media during the study were temperature 25-33oC, pH 4.89-8.40, salinity 25-38.33 ppt, and DO 4.07-7.27 ml / l. The measured value of water quality in culture media was still within the tolerance limits of N. oculata cells so that cells could still grow and divide.

Abstract

This study aims to analyze the level of operational performance and identify the possibility of upgrading the port class of PPI Paotere Makassar city. The research method case study is operational aspect, including facilities provision to evaluate the operational performance. The performance assessment is obtained by comparing the condition at PPI Paotere with the regulation stipulated by The Ministry of Maritime Affairs and Fisheries of Republic of Indonesia Regulation No.PER.08/MEN/2012 and also General Director of Capture Fisheries Decree No.432/DPT3/0T.220.D3/I/2008. The data are analyzed descriptively using table Sscoring method of fishery port type D operational performance. The result shows that the percentage of total production success 1.706,3%, ship visiting frequency 180%, ice service 2.466,7%, fuel service 272,55%, clean water service 52,98% and also port facilities availability such as administration office, international marketing, processing industry, marketing facilities, canteen, worship place, polyclinic and service post, but there are no fishing gear and ship repair facilities, spare parts supply and residence. The operational performance of PPI Paotere has a very good operational performance category that exceeds its capacity as a type D fishing port, but it is no longer possible to increase the port class due to the limited area.

Abstract

This study aims to describe the composition of the species and the frequency of occurrence of fix-liftnet based on the combination of white-yellow-blue and white-yellow Light Emitting Diode (LED). The research was carried out in July – October 2020, by following the operation of capturing 1 unit of fix-liftnet with 442 watts of light power each. Data collection includes the type and number of catches based on trips and grouped into main, by-catch and discarded catches. The results showed that the composition of the type of catch consisted of 26 species dominated by common ponyfish, Indonesian oil-sardine, squid, anchovies, crabs, yellow snakehead and fringesscale sardinella. The total catch of the combination of white-yellow-blue lights was 359.8 kg with main catch 74.4%, by-catch 19.8% and waste 5.9%. While the white-yellow color combination is 343.8 kg with 75.8% main catch, 15.5% by-catch and 8.3% waste. Fish species with 100% occurrence frequency were common ponyfish (Leiognathus equulus), flower crab (Portunus pelagicus), squid (Loligo sp), Indonesian oil-sardine (Sardinella gibbosa), and smooth pufferfish (Lagocephalus sceleratus).

Abstract

The purpose of this research is to map the vulnerability of communities in seven islands of Spermonde. Vulnerability assessment was conducted in July 2013 using an environmental and socio-economical stand point. Identification of the vulnerability issues were grouped into indicators (climate, island morphological, marine resources and socio-economical changes), with each given a scale of 1-5.and attributes in the form of a semi-structured questioner. To check for the type and severity of a disaster, 62 respondents were asked to rank the disaster on a scale of 1-4. Results indicate that the majority of respondents find that change in climate, island morphology, marine resources and socio-economical conditions hardly affect them. The disaster that they fear the most is the danger of losing their source of income. In terms of vulnerability index, Bone Tambu and Lumu-Lumu islands are under very high vulnerability for Island and Socio-economic change. In terms of Climate and Marine Resource change, there are no significant differences among the islands. The trends show that these two categories fall under medium to high, with marine resource dynamic change always being higher than the climate change index, except in Kapoposang Island. Overall, there are no differences between each zonation in vulnerability indexes.
