Though Asian Seabass, which is locally known as "Koral"/"Vetki," is a vital species in terms of its popularity and price, little is known about the location of breeding and nursery ground, peak breeding season, peak harvesting season, population dynamics, harvesting operation (gears and crafts used for harvesting) of this species in Bangladesh. An investigation was carried out to enlist the group of crafts and gears that are being operated on the Bay of Bengal coast by the fishermen for Asian seabass harvesting. The survey was based on interviews with the local fishermen and secondary data collected from the regional fisheries offices. The study revealed a total of 10 distinguishing fishing gears, including seven nets and two types of hook and lines were used for harvesting this fish. Some are selective for harvesting Seabass, but most of them are involved in multi-species exploitation. Four types of motorized and two types of non-motorized traditional boats are being used for harvesting the seabass in Bangladesh. The seabass fishery extends almost throughout the year at different life stages. The Koral net, Mela Barshi (Single Hook and line), and Push net were found to be effective for catching adult, pre-adult, and juvenile Asian seabasses, respectively. The Sampan boat and Mela barshi were reported for the first time as fishing boats and fishing gear in Bangladesh.

Abstract Albuneid crabs are specialized and active sand-burrowing organisms. Despite their substantial diversity, their ability to avoid fishing gear leads to “under collection” and a discontinuous record of distribution. The present study documents the first distributional record of Albunea occulta Boyko, 2002 from the Bay of Bengal, eastern Indian Ocean. Albunea thurstoni Henderson, 1893 is also recorded for the first time from the area, i.e., from the Gulf of Mannar, southwestern Bay of Bengal. This study further reports variation in morphological characters, especially in the carapace grooves (CG) from previous records and across specimens from different regions. Morphometric characters were found useful in species discrimination, which is explained as well.

The research is aimed to reveal opportunity development of the capture fisheries in Talaud Islands Regency by using bionomy approach with Gordon-Schaefer model (Fauzy, 2005) con-cerning the dominant of illegal fishing activities around the area. The research was started by co-llected some secondary data on fish production and number of fishing units. Primary data were collected on catch composition and types of fishing gear. Gordon-Schaefer methods was applied to evaluate the tuna and skipjack resources in the area. The troll and pole and line are indicated as the dominant fishing gears used to catch the skipjack and tuna. In case of open access condition, the production will end up to 25,09 tons, while the resource rent will be end up to zero. For the development, simulations were exercised in 3 scenarios: 1) scenario of enhancing domestic fleet, 2) scenario of illegal fishing, and 3) scenario of net surplus. With those scenarios, if the illegal fishing could be eliminated, the capture fisheries in this regency could render economic value to 10 billion rupiah.

Kabupaten Biak-Numfor merupakan salah satu lokasi yang ditetapkan sebagai Sentra Kelautan dan Perikanan Terpadu (SKPT), yang memiliki potensi untuk pengembangan budidaya laut, sehingga perlu dilakukan kajian kesesuaian lokasi dan daya dukung lingkungannya. Penelitian ini bertujuan untuk mengkaji kesesuaian perairan dan estimasi daya dukung lingkungan (ekologi) untuk pengembangan budidaya ikan kakap (Lates calcarifer). Kajian ini dilakukan di dua lokasi yaitu Pulau Nusi dan Teluk Urfu. Pengumpulan data primer dilakukan melalui survai lapangan dan pengumpulan data sekunder melalui Dinas terkait. Data survai lapangan yang dikumpulkan meliputi: arus, kedalaman, pH, suhu, salinitas, dissoloved oxygen (DO), amonia, nitrit, nitrat, fosfat, total suspended solid (TSS), dan kecerahan. Data sekunder yang dikumpulkan antara lain: Peta RBI dan data spasial dari Rencana Zonasi Wilayah Pesisir dan Pulau-Pulau Kecil RZWP3K Kabupaten Biak-Numfor 2015. Analisis kesesuaian perairan dilakukan dengan perangkat lunak Quantum GIS (QGIS). Analisis spasial berbasis raster. Hasil analisis kesesuaian perairan untuk budidaya ikan kakap dalam keramba jaring apung (KJA), di sekitar Pulau Nusi memiliki potensi yang sesuai seluas 324,11 ha dari total area seluas 2.643 ha, sedangkan di Teluk Urfu area yang sesuai seluas 0,247 ha dari total area 33 ha. Hasil perhitungan daya dukung ekologi, Teluk Urfu tidak direkomendasikan adanya kegiatan budidaya ikan, kenyataannya saat ini telah terpasang 12 lubang KJA. Sedangkan di Pulau Nusi potensi pengembangan budidaya laut khususnya ikan kakap cukup luas. Daya dukung ekologinya adalah 158 lubang KJA (3 m x 3 m x 3 m) dengan terget panen per lubang adalah 175 kg.Biak-Numfor Regency has been designated as one of the locations of Integrated Marine and Fisheries Center (SKPT). The region has the potential to be developed as mariculture area. Thus, it is necessary to determine the site suitability and calculate the environmental carrying capacity of the area for mariculture development. This study aimed to assess the site suitability and estimate the environmental carrying capacity (ecology) of the region waters for Asian seabass/barramundi (Lates calcarifer) mariculture. The study was carried out in two locations: Nusi Island and Urfu Bay. Primary data were collected from a field survey and secondary data was gathered from the local fisheries extension office in Biak

The length-weight relationship of Asian seabass (Lates calcarifer Bloch, Centropomidae) was estimated for the first time based on a wild population; specimens were collected from Pichavaram mangrove waters during October 2003 to September 2004. A highly significant correlation between length and weight, as a relative condition changing in the course of the year, were particularly observed. These data will be certainly useful for the Asian seabass aquaculture development and fisheries.

The potential of marine fish resources in Districts Barru is multi-species, especially pelagic fish. Therefore, in the management and utilization of fishery resources it is very possible for the community to be able to operate various fishing gear. This study aims to determine the composition of the types of fishing gear operated by fishermen in Barru Districts waters of during the pandemic Covid 19. Data collection was carried out from September to October 2020 in around the waters and coastal areas in Barru Districts. This study used a descriptive survey method, by collecting available data (secondary data) in the form of: categories of types and numbers of fishing gears. besides that, field observations will also be carried out. During the pandemic Covid-19, the operation of fishing gear in Barru Districts waters was 13 types of fishing gear, with a composition consisting of four types of fishing gears that were predominantly used, namely 622 drifting gill nets (28.4%), hand lines (21, 7%), Bottom gill nets (19.9%), trolling line (9.6%). Meanwhile, the least used fishing gear was 8 Bagan Tancap (lift net) (0.4%).

Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.
