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.

Abstract

Sungai Cikaso dan Rawa Pesisir Ciroyom, merupakan dua habitat yang dihuni oleh ikan sidat tropis Anguilla bicolor bicolor di Kabupaten Sukabumi, Jawa Barat. Spesies ini merupakan ikan asli Indonesia yang memiliki nilai ekonomi tinggi. Sebagai komoditas ekspor, ikan ini ditangkap pada stadium post larva (glass eel) kemudian dibudidayakan di penangkaran. Informasi kebiasaan makan Anguilla bicolor bicolor dapat digunakan sebagai salah satu bahan dalam perencanaan pengelolaan sidat di alam. Penelitian ini bertujuan untuk mengetahui jenis makanan dan kebiasaan makan Anguilla bicolor bicolor di Sungai Cikaso dan rawa pesisir Ciroyom, Jawa Barat. Kebiasaan makan 54 sidat tropis Anguilla bicolor bicolor dari aliran utama Sungai Cikaso dan saluran parit rawa pesisir Ciroyom, Jawa Barat, diamati antara bulan Juni dan Desember 2020. Pengambilan sidat menggunakan perangkap dan pancing. Setiap sampel ikan sidat diukur panjangnya. Ikan dibedah dan isi perutnya diawetkan dengan formalin 5%. Sampel dikelompokkan berdasarkan kelas panjang yaitu 20 - 25 cm, 25 - 30 cm, 30 - 35 cm, dan 35 - 40 cm. Index bagian terbesar (Index of preponderance) digunakan untuk mengetahui jenis makanan dan kebiasaan makan Anguilla bicolor bicolor. Dominasi kepiting sebagai makanan ikan sidat menunjukkan bahwa sidat sebagai ikan karnivora. Data yang dikumpulkan dari pengamatan laboratorium menunjukkan beberapa jenis makanan yang dikonsumsi ikan sidat, yaitu; kepiting, udang, serangga, ikan, Annelida, bagian tumbuhan, dan fitoplankton. Makanan utama ikan ini saat berukuran kecil adalah serangga, dan memakan kepiting saat mereka berukuran lebih besar. Cikaso River and Ciroyom Coastal Marsh were two habitats that inhabited by tropical eel, Anguilla bicolor bicolor in Sukabumi Regency, West Java. This species was Indonesia's native fish that had a high economic value. As export commodity, this fish caught in the post larvae stage (glass eel) then grow in captivity. The food habit information of Anguilla bicolor bicolor can be used for management planning of eel in the wild. This study aimed to determine the food and feeding habit of Anguilla bicolor bicolor in Cikaso River and Coastal Swamp of Ciroyom, West Java. The food habits of 54 tropical eels, Anguilla bicolor bicolor, from mainstream of Cikaso River and ditch channels of Ciroyom Coastal Marsh, West Java, were examined between June and December 2020. Eels were collected using traps and hook and line. The length of each fish was measured. The fishes were dissected and the stomach of eels was preserved by formalin 5%. The samples were grouped as 20-25 cm, 25 to 30 cm, 30 to 35 cm, and 35 to 40 cm. Index of preponderance was used to determine the feeding habits of Anguilla bicolor bicolor. The domination of crab as a diet of eel indicates that eel as carnivorous fish. Data collected from laboratory observation showed some foods consumed by eels; crab, shrimp, insect, fish, Annelida, vegetation, and phytoplankton. This fish feed mainly on insects when small and feed mainly on crabs as they grow.
