The aim of this research was to determine the condition and status shrimp fisheries in Bintuni, Sorong, South Sorong Regency. This conducted from May July 2019 center industry. Variables measured study include fisheries, production data for 10 (ten) years, conditions availability, size, type obtained through interviews using questionnaires used obtain an overview stock nature. Analysis estimati...

Ponds are common in many agricultural landscapes and provide aquatic habitat for wildlife. Most studies of semi-aquatic turtle assemblages have been conducted in lotic environments or large lentic habitats (e.g., lakes, reservoirs), but few studies have described pond communities. We used Frame nets and basking traps to sample turtle assemblages within eight ponds located in east-central Kansas...

Skipjack tuna (Katsuwonus pelamis) is the main catch species in Indonesian Palabuhanratu waters. The dynamics of skipjack fishing areas are influenced by oceanographic parameters such as sea surface temperature and chlorophyll-a concentration. This study aims to predict season, analyze conditions, especially distribution chlorophyll-a, determine relationship between season waters Palabuhanratu,...

Over-exploited fisheries are a common feature of the modern world and a range of solutions including area closures (marine reserves; MRs), effort reduction, gear changes, ecosystem-based management, incentives and co-management have been suggested as techniques to rebuild over-fished populations. Historic accounts of lobster (Jasus frontalis) on the Chilean Juan Fernández Archipelago indicate a...

Oceanic temperature fluctuations are one of the leading factors affecting marine fish populations. Indian Ocean Dipole (IOD), characterized as sea surface (SST) anomaly change, is an ocean–atmosphere interactive process causing interannual climate variability in Ocean. Influences IOD on tuna catch rates supported by previous research. Yet, there remains limited information about impacts abundan...

the aim of the present research is to survey the effects of environmental and biological factors on rutilus frisii kutum migration in the southwest region of caspian sea. for this purpose sampling was carried out by gillnet cooperatives company in tonekabon city  from november 2013 to april 2014. the total catch per unit effort  was calculated as 220 kg. rutilus frisii kutum  contains 69% of th...

Marine reserves have increasingly been recognised for their potential to address the pervasive problem of unsustainable harvest of fisheries worldwide. Abalone catch around Stewart Island has been in decline since the turn of the century despite being managed under NZ’s quota system. A nested logit model is applied to spatially recorded catch and effort data between 1998 and 2003 to capture the...

Assessing patterns of fisheries activity at a scale related to resource exploitation has received particular attention in recent times. However, acquiring data about the distribution and spatiotemporal allocation of catch and fishing effort in small scale benthic fisheries remains challenging. Here, we used GIS-based spatio-statistical models to investigate the footprint of commercial diving ev...
