Abstract

Scientific information about the composistionand structures of mangrove community and zonation patterns, became a basic data to support further fisheries research and development. As one of the reference for Dompu government policy on the fisheries recovery plan in Cempi bay data and information of mangrove in this area were very important. The study was conducted at Cempi bayon the year 2011-2012 by exploration the area nearby research station. The results showed that the mangrove forest has already been heavy disturbed and degraded. The mangrove forest at Mbawi only which has a high density and  good crown coverage. The mangrove species grown in these areas were belonging to the family Rhizophoraceae and Aviciniaceae. The presences of mangrove spesies were supported by environmental factors, such as muddy sandysubstrats and extreme deferences of salinity (3-36o/oo). Recovery of mangrove forest was important to be conducted in order to support the catch shrimp productivity in bay of Cempi. Key Words : Mapping, Composition,  Mangrove, Management of Fish Resources, Cempi Gulf

Abstract

Informasi tentang sumberdaya kuda laut sangat terbatas, dari 35 jenis kuda laut di dunia yang terdaftar dalam IUCN redlist, 20 jenis terdaftar sebagai “data deficient” yang menggambarkan kurangnya informasi terkait kuda laut, bahkan untuk jenis yang sangat tereksploitasi. Penelitian ini dilakukan untuk menginventarisir sumberdaya kuda laut (Hippocampus spp.) meliputi informasi jenis, ukuran, nisbah kelamin dan kepadatan kuda laut dari tiga lokasi potensial, yaitu perairan Pulau Bintan, Teluk Lampung dan Pulau Tanakeke. Observasi lapangan dilakukan pada tahun 2016 dengan metode purposive sampling, wawancara dengan para nelayan dan pengepul kuda laut serta studi pustaka. Hasil penelitian menunjukkan adanya perbedaan sumberdaya kuda laut yang ditemukan di ketiga lokasi penelitian. Jenis kuda laut paling banyak ditemukan di perairan Bintan, sebanyak empat jenis (H. comes, H. spinossisimus, H. hystrix, dan H. kuda), diikuti Teluk Lampung dua jenis (H. comes dan H. kuda) dan di perairan Tanakeke hanya ditemukan satu jenis (H. barbouri). Sebagian besar kuda laut yang ditemukan selama penelitian dikategorikan sudah matang secara seksual dimana kuda laut yang mendominasi berukuran 11-12 cm. Jenis dan kepadatan kuda laut yang berbeda di ketiga lokasi penelitian didukung oleh perbedaan habitat dimana kuda laut ditemukan. Kepadatan kuda laut di ketiga lokasi penelitian cenderung rendah akibat eksploitasi yang berlebihan, perubahan lingkungan dan kerusakan habitat. Langkah pengelolaan berbasis aspek biologi dan kondisi ekologi dari masing-masing wilayah perlu dilakukan untuk perikanan kuda laut yang berkelanjutan.

Abstract

Graphical Abstract Highlight Research The results of this research showed that allometric growth in males and females had negative allometric growth characteristics. The growth condition index in male and female fish is dominated by thin and fat body shapes.The maximum length growth (L∞) and growth speed of males is higher than that of females. Total mortality and fishing mortality for males is higher than for females, but natural mortality for females is higher than for males. The exploitation rate of males and females is in the Under-exploitation category because the E value is <0.5. Abstract Exploring the length-weight relationship of fish and characterising growth parameters is essential in fisheries as they offer fundamental biology and population dynamics data to establish good management strategies for fisheries resources. This study examines the growth and mortality patterns of Oreochromis mossambicus. Data was collected between September and December 2022 using quantitative descriptive survey sampling. The study involved 20 repeats and deliberate random sampling of 30-50 fish per sample, emphasising total length, weight, and sex parameters. Based on 726 samples of O. mossambicus (352 fish identified as male and 374 fish identified as female). The growth model study revealed the typical negative allometric growth for both sexes (male and female). Male individuals attained a length of 33.449 cm after 37 days has a growth trend ± 0.3265 year-1, and females reached 21.150 cm in 34 days with a growth rate around 0.3135 year-1, as per the von Bertalanffy growth model. There were complex mortality patterns, with males contributing to most total deaths. This study emphasises the complex biology of tilapia and its untapped potential in the aquaculture pond system ecology in Tarakan.
