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

This study aimed to describe the development of types of fishing gear in the waters of the east coast of Sumatra from Belawan Waters to Serdang Bedagai Waters and to examine the perceptions of fishers based on the social characteristics of fishers towards environmentally friendly fishing gear based on the Code of Conduct for Responsible Fisheries (CCRF). The method used in this research is descriptive research using the survey method. The population in this study were fishers based in Belawan and Serdang Bedagai waters and using traps and gill nets, as many as 6943 people, with the simple sampling method or slovin method, the results of the sample count were 100 people from the population. Based on eight categories (CCRF) to understand fishers' perceptions of environmentally friendly fishing gear, including the level of selectivity, biodiversity, ecological diversity, not destroying habitat, the safety of fishers and consumers, based on social conditions, based on biodiversity, and based on fish quality, the level of very understanding is 13.2 %, understand 25.2%, neutral 26.7%, don't understand 23.3% and don't understand 11.4%. This study results indicate that the respondents, in general, have begun to realize environmentally friendly fishing gear based on the CCRF.

Abstract

The population of Thunnus albacares yellowfin tuna from the Scombridae family is very abundant in North Papua Waters (WPP 717). This study aims to analyze the parameters of population dynamics based on the long-weight relationship and condition factors on Thunnus albacares in Demta Coastal Waters, Jayapura Regency. Fish data collection uses passive and active fishing methods using gill nets, handlines, and long line fishing through fishing activities by traditional fishermen during April - June 2022. Data analysis uses analysis length-weight relationship and condition factor. The results of this study found that the population structure of yellowfin tuna (T. albaceras) was very diverse in the waters of North Papua, with a negative allometric growth pattern (b < 3), i.e. the growth of body length was faster than weight. The condition factor averaged 1.1302 with a maximum of 1.4718 and a minimum of 0.7028. Where in the gonadal maturity period morphometric adaptation occurs, weight growth becomes faster and body length becomes slower.
