Abstract

Seaweed (Kappaphycus alvarezii), in terms of providing seeds in cultivation activities, is still carried out vegetatively, namely cutting the thallus (cuttings), which is then cultivated until it is ready to be harvested (Rao & Reddy, 1997). However, such a method will experience problems, especially the provision of quality seeds on a large scale, and it does not depend on the season. The possible alternative to do is by generative seeding method. K. alvarezii can be developed for cultivation by utilizing the nature of generative reproduction through the development of carpospores, characterised by cystocarps on the surface of the thallus. However, the cystocarp that has been formed needs nutrients in the development process to produce spores of good quality and quantity. Nutrients that are needed to support cystocarp development include nitrogen and phosphate. The benefits of nitrogen and phosphate for seaweed growth cannot be replaced with other elements. This is due to the role of nitrogen as a constituent of protein and phosphate as an energy provider. This study aimed to determine the optimum nitrogen and phosphate enrichment ratio for cystocarp development. The research was carried out from November 2018 to February 2019 at the Seaweed Laboratory of the Takalar Brackish Aquaculture Fisheries Center (BPBAPT). The research location is Mappakalompo Village, Galesong District, Takalar Regency, South Sulawesi Province. They were analyzed at the water quality laboratory of Hasanuddin University to analyse the N and P content in the media. There were 6 treatments with 3 replications each, namely Treatment A: Without enrichment (SW), Treatment B: 1N=0.5 ppm: 1P=0.5 ppm, Treatment C: 2N=1 ppm: 1P= 0,5 ppm, Treatment D : 3N=1,5 ppm : 1P=0,5 ppm, Treatment E : 1N=0,5 ppm: 2P = 1 ppm, and Treatment F : 1N=0,5 ppm : 3P = 1.5 ppm. The results showed that the development of a shorter cystocarp phase was found in treatment D, which was 14 days. Meanwhile, treatment with a long time of 17 days occurred in treatment A (SW).

Abstract

Income of hand line fisherman very dependent on the influence of nature and the existence of a working relationship between boat owners and labor fishermen in fishing operations. This study aims to analyze the profit-sharing and income-sharing system of hand line fishermen at Hila Village, Central Maluku District. Primary data was collected through interviews with 6 fishermen and analyzed using the business income equation and profit sharing system as well as the amount of income earned by fishermen. The results showed that hand line business income of Rp23.093.023/month and the application of the profitsharing system is 1:3 for owner fishermen, boats and 1 crew member. However, the boats's share becomes the property of the owner fisherman, so the owner fisherman gets 2 shares and the crew gets 1 share. The income obtained based on the profit sharing system is the owner of Rp15.393.349/month and the crew of Rp7.697.674/month.

Abstract

The sustainable use of fish resources is closely related to fishing practices by fishermen. It is a classic problem that utilizing marine and fishery resources, the exploitation method carried out by fishermen often does not consider environmental sustainability aspects or is contrary to the principles of responsible fisheries management (Code of Conduct for Responsible Fisheries - CCRF). This study aims to examine IUU fishing activities from the socio-economic dimension, which under certain conditions will produce its own understanding, especially when it comes to traditional rights, resource share allocation, and the level of dependence on fishery resources. The type of research is qualitative research with a case study method. Data collection techniques are observation, interviews, and literature study. The data collected includes primary data and secondary data. The data analysis technique used is the content analysis method through the stages of data reduction, data presentation, and drawing conclusions. The results of this study indicate that illegal fishing that occurs in the Spermonde Islands is dominant due to the pressure to fulfill economic needs, other factors are the low understanding of the importance of sustainable use of fishery resources; increasing demand for foreign markets, especially live fish; and inconsistency and weak law enforcement in preventing the use of explosives and drugs. Empirical data on resource potential is required and integrated into policy formulation in the form of responsible fisheries, including other activities that can be done by fishermen as alternative livelihoods, and ecosystem approaches for conservation and management of fish stocks of related species.

Abstract

Suckermouth catfish (Pterygoplichthys pardalis) are found in Lake Tempe, Wajo Regency, but their existence has not been utilized so far and is even considered the cause of the loss of several endemic fish species in the lake. This study aims to determine the chemical characteristics and the preference level of sticks fortified with Suckermouth catfish (Pterygoplichthys pardalis) meal as an effort to utilize these fish. The research method used was experimental with treatment of SK (control without adding Suckermouth catfish flour), S1 (addition of 10 g of Suckermouth catfish flour), S2 (addition of 20 g of Suckermouth catfish flour), and S3 (addition of 30 g of Suckermouth catfish flour). The parameters observed were moisture, protein, fat, carbohydrate, and ash content, and the level of preference (hedonic test). The results showed that the panelists tended to say they really like the appearance and flavour of the stick S1 product, and very much like the taste and texture of the stick S3 product. The highest protein and water content was in S3 treatment, the highest ash and carbohydrate content was in SK treatment, and the highest fat content was in S1 treatment
