Abstract

The use of vermiculated spinefoot has been carried out intensively so that it is suspected to have caused phenotypic changes. The objective of research to identify phenotypic characteristics which include morphometrics and meristics. This research was conducted February to April 2022 using a survey method in the Pangkep waters of the Makassar Strait. The samples identified were 45 individuals from five places namely the islands of Sabangko, Salemo, Sagara, Bangko-Bangkoang and Laiya. Each island identified nine fish with representation of small, medium and large sizes. Identification of morphometric characteristics was carried out on 29 parameters, while meristic characteristics on the number of strong and weak rays of the dorsal, pectoral, abdominal and anal fins. Data were analyzed using principal components and cluster analysis. The results showed that the main and very strong characteristics of the vermiculated spinefoot from the five sampling locations were anal fin base length, pelvic fin base length, head length and head width, the length of the longest anal fin rays for all sizes. The morphometric characteristics of the five islands obtained varied conditions with two morphometric groups namely the small and medium size vermiculated spinefoot fish group and the large vermiculated spinefoot fish group. The meristic characteristics of the dorsal, pectoral, pelvic and anal fins of the five islands are relatively the same. Based on the morphometric characteristics, vermiculated spinefoot fish should be managed separately, namely small and medium sized fish with the same management model, while large sized fish should be managed separately.

Abstract

Since 2016, tilapia fish farming has begun to be developed in Puncak Jaya Regency, especially in several districts in the capital city of the district, including Mulia District, which is the center for developing tilapia fish farming areas. Puncak Jaya Regency is located in a mountainous area with an altitude of 500 - 4000 mbpl with an average of 2237 mbpl above sea level. These geographical conditions are obstacles that must be overcome to develop tilapia fish farming which is highly demanded and needed by the mountain community to meet their daily nutritional needs. This study aims to 1) Analyze the factors and potential of fish farming. 2) fish farming development strategies in the city of Puncak Jaya Regency. The method used was to conduct interviews with questionnaires to business actors in farming, related agencies and officials at the regional government level and the DPRD, then analyzed with IFE and EFE Analysis and to determine the strategy, a SWOT analysis was carried out. The results of the study showed 1) business actors in farming were productive age cultivators with a high school education level (33%), small business scale (40%) and production results of 100 - 250 kg / cycle (46.7%); 2) Internal and external factors that have a great influence are geographical location, government support, fish prices, consumer needs and security which are the main threat factors; 3) Development strategies to increase production by adding cultivation ponds, developing alternative artificial feed with local raw materials, assisting independent seed production and government support to overcome security threats by distributing assistance for cultivation facilities and infrastructure more evenly to all heterogeneous social groups.
