Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic fish in the Halmahera Sea. This species is distributed and found in the Kao Bay sea. The International Union for Conservation of Nature (IUCN) data shows that the Halmahera Walking Shark is in the Near Threatened status. Protection is carried out to protect the population, therefore scientific data and information are needed. This study focuses on the biological structure of the Halmahera Walking Shark population in Kao Bay sea. Data collection was carried out exploratively in coral reef, seagrass, mangrove ecosystems and by-catch. Samples were taken for morphometric data, weight and sex. Morphometric data were analyzed to obtain cohorts, separation index, class intervals, length-weight relationships and condition factors of walking shark. The result were found to be 33 individuals (13 male and 20 female). Morphological characteristics based on morphometric variables found no significant differences. Analysis of the cohort of the Halmahera Walking Shark (H.halmahera) found 3 groups namely the juvenile, mature and old age phases. The separation index shows that individuals come from different populations based on length. Growth pattern of the Halmahera Walking Shark (H.halmahera) is negative allometric. The histogram of the frequency distribution between classes found small to large size structures with different relative frequency percentages. The condition factor found that the body proportions of the Halmahera Walking Shark (H.halmahera) were in the plump category. All of this information is important to provide scientific data specifications to population.Keywords : Endemism, Halmahera, Morphology, Island, Semi enclosed

Abstract

North Maluku Province is an archipelagic province that has a sea area of 113,796.53 km2 or 70% of the land area. As an archipelagic area, North Maluku waters have high biodiversity. One of the important biota in North Maluku waters is the eel. Eel is one of the water resources that have high economic value, because of its nutritional contentEel (Anguilla sp) is a catadromous fish that begins its life in the larval or juvenile phase in marine waters and grows up in brackish and fresh waters. This study aims to determine the distribution of eel species (Anguilla sp) in the seas and the morphometric eel (Anguilla sp) in kayoa waters. The results showed that the number of eels found at both stations was 13 tails. The results of the morphological analysis showed that the type of eel found at both stations was A. marmorata, the morphometric identification results showed that at station 1, the total length range was 50 - 106 cm, with a weight of 460-4100 grams, while at station 2 obtained a length range of 65 cm - 83 cm, with a weight of 79 -1300 grams. Key Word: Area, Morphometri, Anguilla, Small Island, Tropis
