Abstract. Wijaya A, Zakiyah U, Sambah AB, Setyohadi D. 2020. Spatio-temporal variability of temperature and chlorophyll-a concentration sea surface in Bali Strait, Indonesia. Biodiversitas 21: 5283-5290. The Strait is influenced by seasonal inter-annual systems. El Nino-Southern Oscillation (ENSO) Indian Ocean Dipole (IOD) are climate variabilities that affect water conditions. knowledge about influence ENSO IOD variations on the fertility waters still lacking. purpose this study was to...
Background. The paternal mouthbrooding Banggai cardinalfish, Pterapogon kauderni Koumans 1933, has an exceptionally restricted endemic range for a marine fish, is traded internationally as ornamental and listed endangered in the IUCN Red List. This paper aims to contribute body of knowledge regarding biology this species, based on studies population Archipelago introduced Palu Bay, Central Sulawesi Province, Indonesia. Materials methods. Length frequency data collected over period 2004–2012...
Understanding the impact of Indian Ocean Dipole (IOD) on fishery around Indonesia is important as resources are small compared to demand. In this study, we analyzed effect positive and negative phases IOD chlorophyll-a concentration catch Sardinella lemuru in Bali Strait. Data based field surveys Strait during phase Sea Surface Temperature (SST) Chlorophyll (SSC) obtained from analysis satellite images. The results suggest that SSC strait significantly correlates with IOD, possibly through a...
This study aims to find scientific data concerning distribution pattern of R. argyrotaenia , catch composition including length frequency data, fishing peak season, spawning and abiotic characteristics aquatic environment, such as life . The findings indicate that during rainy season (January-April) is scattered in main river, tributary, marsh (flood plain), dry (May-August), position fish river while transitional months (September-December), concentrated river. Fishing occurs April, May,...
ABSTRAKPulau Sempu adalah satu-satunya cagar alam yang berada di Kabupaten Malang memiliki terumbu karang dengan luasan kurang dari 10 ha mampu bertahan banyaknya ancaman berpotensi merusaknya. Faktor lingkungan secara alamiah telah menyeleksi keanekaragaman diwilayah perairan P. Sempu, yakni hanya 9 life form keras berperan sebagai penyangga ekosistem wilayah ini. Mengetahui distribusi ukuran koloni sama pentingnya mengetahui umur untuk melihat kondisi pada suatu perairan. Klas frekuensi...
Abstract. Setyohadi D, Rahman MA, Harlyan LI, Rihmi MK. 2024. Species identification and population dynamics of cuttlefish Sepia spp. (Mollusca: Cephalopoda) landed at Brondong Fishing Port, Lamongan, East Java, Indonesia. Biodiversitas 25: 1359-1367. Cuttlefish (Sepia spp.) is one Indonesia’s fisheries resources with high economic value. It often caught in the northern Java waters, including Lamongan. As it value, should be managed to ensure sustainability. However, information on its...
The research was conducted at Bali Straits on April to September 2007. aims of this study were (1) estimate potential sustainable yield (MSY) and total allowable catch (TAC); (2) status exploitation; (3) make some scenario the alternatives fisheries management. Catch-effort data time series taken from Fisheries Statistics Report Bali. analysis performed by using holistic models as stated Walter & Hilborn (1976) Schnut (1977). result showed that reserve oil sardine (Be); MSY TAC 208,152.2;...
Abstrak Penelitian ini bertujuan untuk mengetahui pola pertumbuhan, nisbah kelamin, faktor kondisi, dan struktur ukuran ikan S. boops yang tertangkap di perairan sekitar Bitung. dilakukan Pelabuhan Perikanan Samudera Bitung pada bulan Februari-Juli 2016. Sampling dianalisis berjumlah 846 ekor terdiri dari 430 (50,83%) jantan, 357 (42,20%) betina serta 59 (6,97%) tidak teridentifikasi. Kisaran panjang cagak (FL) antara 8,60-23,60 cm (rerata 16,45 ± 3,34 cm) bobot tubuh berkisar 10,00-257,50 g...
Highlight ResearchThe feedback harvest control rule resulted in the lowest allowable biological catch estimation than surplus production models. The adapted recent years of historical data.The models might result over or under estimation, not considering data.This multispecies fishery could provide species specific data as required; therefore, it be better to use that has been validated for fisheries. AbstractScads Blitar waters is a applying rules (HCRs) from conventional single-species...
ABSTRACTThe Banggai Cardinalfish (Pterapogon kauderni) or capungan (often abbreviated as BCF) is a marine fish endemic to the waters around Archipelago, caught in large numbers for aquarium trade. The conservation of this species became an international issue, 2007 BCF was proposed CITES listing by USA and listed Endangered IUCN Red List. proposal withdrawn, with Indonesia committed conserve through sustainable ornamental fishery approach. multi-stakeholder Action Plan (2007-2012) other...
The reef flat area in Pantai Kondang Merak is similar to others that are influenced by the high and low tide. Coral this should deal with water temperature during tide withstand exposure air. These conditions lead coral stress. Another stressor heavy metals such copper. Annual band Porites lutea can be a bioindicator investigate metal contaminations as resulted from human natural activity. To measure copper skeleton, we used ICP-OES (iCAP 7400 Series). Heavy was absorbed tissue bind their...
