Abstract

The demand for Gracillaria commodities continues to increase for food, medicines, and beauty ingredients. These conditions encourage the cultivation of this commodity continues to proliferate. Because of that, availability of Gracillaria sp seeds is available both in quantity and quality. One effort that can be done in handling the Gracillaria sp spores through environmental engineering. One such factor is fisheries salinity. The difference in salinity supports the increase in Gracillaria spores so that it affects spore growth. The aim of the study was to study the growth of Gracillaria spores cultured on different salinity media. The method used is a laboratory experiment method with a completely randomized trial design (CRD) with forty salinity preparations (23 ppt, 26 ppt, 29 ppt, and 32 ppt) and is repeated three times. The resulting data were then analyzed by analysis of variance. The results showed the highest spore growth at 23 ppt salinity with the number of spores (560.9 Ind / cm2), then 26 ppt salinity (438.8 Ind / cm2), then 32 ppt salinity (429.9 Ind / cm2) and low in salinity 29 with the number of spores (277.8 Ind / cm2). Fingerprint analysis showed that each evaluation results were not significantly different.

Abstract

Banggai Islands-Central Sulawesi-Indonesia holds one of the endemic marine biodiversity, the Banggai Cardinalfish (Pterapogon kauderni). The Banggai Cardinalfish has been listed as Endangered on the IUCN (International Union for the Conservation of Nature) Red List since 2007, and the 17th CITES CoP in appendix II of CITES in 2016. There are two main threats to the species, namely utilisation as ornamental fish and habitat degradation. This study aims to determine the sustainability status of Banggai cardinalfish in Banggai Laut Regency. This research was conducted from January to March 2024 in three villages (Popisi Village, Tolisetubono Village and Bonebaru Village) in North Banggai District, Banggai Laut Regency, Central Sulawesi Province. This research uses descriptive qualitative methods, which uses primary and secondary data to assess the five dimensions of sustainability of Banggai Cardinalfish management: ecological, social, economic, policy and institutional dimensions and technology and infrastructure. Each data obtained will be scored to get the median value of each attribute. The scoring data obtained from each attribute was analysed with RAPFISH (Rapid Appraisal for Fisheries) to reflect the sustainability position with a scale score of 0% (poor) to 100% (good). The results showed that the multidimensional sustainability index of Banggai Cardinalfish management is 54.70 which means that the sustainability status of Banggai Cardinalfish management is quite sustainable, with the value of each dimension showing the value of ecology (70.05), social (64.12), economy (43.34), policy and institutions (36.92) and technology and infrastructure (58.06).
