Abstract

In order to optimally utilize marine fishery resources, the Government of the Republic of Indonesia divides Indonesian waters into 11 Fisheries Management Areas (IFMA), one of which is IFMA 713 which includes the waters of Bone Gulf, Bali Sea, Flores Sea and Makassar Strait. This study aims to provide information on the utilization of pelagic fish resources with a focus on the characteristics of fishing areas using purse seine fishing gear in the Makassar Strait and Flores Sea. In this study, 62 fishing trips using purse seines were carried out, each has 31 trips fishing operation in the Makassar Strait and in the waters of Flores Sea, respectively. The main catch and number for each water area was skipjack tuna (Katsuwonus pelamis) as many as 2,367 fish (Makassar Strait). While in the Flores Sea area, it is dominated by little tuna (Euthynnus sp) with a total of 11,039 fish. The results of this study indicate that the correlation of sea surface temperature with chlorophyll-a in the waters of the Makassar Strait and Flores Sea has a negative relationship with an optimum sea surface temperature of 30.5 °C for skipjack tuna and 28.0 °C for little tuna which corresponds to the chlorophyll-a concentration of 0.3 mg m-3 (skipjack tuna) and 0.2 mg m-3 for little tuna. The vertical distribution of skipjack tuna was found at the optimum depth of around 50 m, while most little tuna was caught in deeper waters around 250 m.

Abstract

Seaweed (Kappaphycus alvarezii) is one of the aquatic commodities that has the potential to be developed due to demand reaching the international market (Ari, SP and Risna Yusuf, 2018). Provision of seeds is still carried out by vegetative means (cuttings) (Runtuboy N and Slamet Abadi, 2018). However, there are problems, especially the provision of quality seeds, large scale, and does not depend on the season. Provision of seeds can also be done generatively. K. alvarezii can be developed by exploiting the nature of sexual reproduction through the development of spores which are characterized by the presence of cystocarp on the surface of the thallus (Juniarta I, 2016). However, the cystocarp in its growth really needs nutrition in order to produce spores of good quality and quantity. The nutrients needed are nitrogen and phosphate. This is due to the role of nitrogen as a constituent of protein and phosphate as a provider of energy (Pauwah A, et al., 2020). The purpose of this study was to determine the dose ratio of nitrogen and phosphate enrichment on cystocarp development. The research was carried out from November 2018 to February 2019, at the Seaweed Laboratory of the Takalar Brackish Water Aquaculture Fishery Center (BPBAPT). The study contained 6 treatments with 3 repetitions, namely Treatment A = Without enrichment (SW), Treatment B = 0.5 ppm N: 0.5 ppm P, Treatment C = 1 ppm N: 0.5 ppm P, Treatment D = 1.5 ppm N : 0.5 ppm P, Treatment E = 0.5 ppm N : 1 ppm P, and Treatment F = 0.5 ppm N : 1.5 ppm P. The results showed that the highest germination was in treatment D with an average of 56.95%. However, the research was not significantly different between treatments (p>0.05).

Abstract

The rapid development of electrical technology in the field of fishing, especially utilizing the light to collect fish into the catchable area. Generally, Light emitting diode (LED) lamps for fishing are placed above the water surface. The success of this technology has become the basis for conducting experiments with the position of the lamp in the water to see its effectiveness as a fish collection device. The aim is to develop the application of light fishing technology by; (1) testing the effectiveness of using LED lights in collecting fish in the fixed lift-net catchable area to increase the number of catches; (2) assessing the quality of the catch, namely main and by-catch. The research was carried out in May-October 2022 in the Pangkajene and Islands Regency waters. The case method is one unit of fixed lift-net using 4 units of LED underwater lights with a power of 60 W. Data collecting with experimental fishing, namely following fishing operations for 40 trips. The parameters analyzed were the number and types of catches and the effectiveness of fishing gear based on fishing trips. The results showed that the catches types obtained were 15 species with 101.72 kg total catch. The number of catches is not significant, but the results of this study provide one hope, especially for Mitra fishermen. The innovation of LED underwater lights is new information that has good prospects as a more effective and environmentally friendly light capture device.

Abstract

Improving the quality of traditional farmers on a technical, social and economic scale, is strongly influenced and determined by the capacity to carry out pond business activities related to managerial patterns and work relationships that are formed.  This research was conducted in October – December 2021. Milkfish (Chanos-chanos) aquaculture business in Bonto Manai Village was chosen as the case, because the aquaculture system managed by the community is dominated the traditional aquaculture system. The purpose of this research is to analyze the knowledge of traditional aquaculture as a technical practice in managing aquaculture businesses, as well as to analyze the work relations of traditional aquaculture businesses which are internalized in the local culture of the community. The methodology used is a case research method with a descriptive qualitative data analysis approach described in the life history of the informants. The results showed that traditional farmers in milkfish (Chanos-chanos) aquaculture in Bonto Manai Village have acquired knowledge gained through experience passed down from generation to generation, starting from the construction and management of pond subgrade, seed stocking, rearing, harvest and post-harvest. Accompanied by rituals based on belief as a traditional value. The managerial pattern and work relations in the management of traditional pond business have three types of management, namely; aquaculture business which is self managed by the owner of the aquaculture land with involving two to three workers, aquaculture business which is managed based on a leasing system, and aquaculture business which is managed by a rapture system.

Abstract

Governance (policy) that regulates fisheries resources needs to involve industry in the supply chain (market) and small-scale grouper fishermen (community) within a co-management framework so that management is more effective while simultaneously supporting the Fisheries Improvement Project (FIP) which is driven by various parties globally (Conservation Alliance, 2021). This study aims to recommend a small-scale grouper fishery co-management model to be carried out in South Sulawesi Province. This study diagnoses the readiness (enabling condition) and willingness (motivation) of stakeholders so that they can be applied and implemented consistently (implementation). The results of this study indicate that the main approaches and strategies for the co-management model of small-scale grouper fisheries include (a) Optimizing the role of the market that promotes traceability and improving governance through a supply chain approach, (b) Synergy and synchronization of the role of government at all levels through an approach technocratic, (c) Strengthening fishermen and local institutions through a participatory approach, (d) Gathering multi-stakeholder support and collaboration through a collaborative approach. The recommended roadmap for small-scale grouper co-management in South Sulawesi Province includes three main stages, namely: (a) Initiation Stage: Commitment, Support, and Organizing, (b) Acceleration Stage: Joint Committee and Co-management Prototype, and (c) Stage Institutionalization: Scaling up and Organizing Fishermen's Forums.

Abstract

Management of small pelagic fish resources is one of the efforts to prevent a decrease in the carrying capacity of small pelagic fish resources which has continued to experience a decline in production capacity in Buton Regency since the last 5 years since 2016. This study aims to analyze CPUE (Catch per Unit Effort), sustainable potential (MSY) and level of utilization and level of exploitation so that it can become information for managing the utilization of small pelagic fish resources. The research method used analysis of the level of utilization and level of effort based on statistical data on fisheries production for the 2016-2020 period. The results of this study indicate that there is a relationship between CPUE and fishing effort, namely a decrease in CPUE of 0.4092 tons for every increase of effort of 1 effort, optimum catch value (CMSY) of 9447.04 tons per year, and optimum effort value (EMSY) of 152 attempts per year, the utilization rate is still below CMSY with an average of 7557.64 tons and the utilization rate has exceeded EMSY with an average of 178 units per year. The average value of the utilization rate for small pelagic fish in Buton Regency is 94.56%, meaning that it has exceeded the Total Allowed Catch (TAC) but not exceeded the MSY value, while the average effort level is 116.84%. This means that fishermen's catches can still be optimized, but may not exceed MSY, which is 9447.04 tons per year. Trends in the level of utilization and effort level of small pelagic fish resources in the last five years indicate that the utilization rate of small pelagic fish resources has decreased in line with increasing levels of exploitation each year.

Abstract

Pink shrimp (Metapenaeus affinis) or Jinga shrimp is one of the species caught in the waters off Samboja Kuala. This catch is a valuable commodity in the market. The possibility of exploiting shrimp resources will be jeopardized in an effort to conserve, utilize, and catch high intensity shrimp. This study was conducted from September to December 2022 with the aim of determining population dynamics parameters using the frequency method from carapace length data. A mini trawl was used to collect shrimp in the waters of Samboja Kuala, Kutai Kartanegara Regency. Male and female jinga shrimp have a ratio of 1:2,43. Furthermore, for male and female shrimp, the growth rate coefficient (K) was 0,580 and 14,00, respectively, and the approximated natural length (L) was 145.82 and 160.81. Pink shrimp (Metapenaeus affinis) have natural mortality (M) of 1,113/year, mortality due to capture (F) of 0,516, and total mortality (Z) of 1,630, with exploitation value (E) of 0,316, indicating that they are still at the appropriate level. Herefore, female shrimp peaked in August at 14,6% and males peaked in July 31,81%. The Y/R capability was 0,049/year, and Emax calculated the Y/R relationship with the exploitation rate, which was 0,42.
