Densities of nekton were estimated by comparing catch rates of two previously uncompared gear types, a beam trawl and a seine net, by day and night in a shallow seagrass (Zostera capricorni) habitat in Moreton Bay, Queensland, Australia. A total of 39,676 fish and crustaceans representing 42 species was caught. The catch rates of nekton were 1.4–68.1 times higher at night than in the day for 8 ...

—Catch-and-release practices are common in recreational fisheries, yet little is known about the behavior, physiology, and ultimate fate of released fish. We used a combination of radiotelemetry (external attachment) and nonlethal blood sampling (i.e., the blood concentrations of lactate and glucose and plasma concentrations of aspartate aminotransferase (AST), Naþ, Kþ, and Cl ) to assess the r...

It has been estimated that the optimal yield of red hake, Urophycis chuss (also called squirrel hake, mud hake, and ling), is 32,000 metric tons (t). This is an increase from the 1978 optimal yield estimate which was 16,000 t. The international catch of this fish from Georges Bank in 1977 was 2,879 t with the U.S. commercial catch being just 96 t. Thus, there is an abundant resource of this spe...

[1] Workshops to identify transboundary and basin-wide environmental issues and a diagnostic study by consultants identified priority environmental concerns of resource managers in the lower Mekong River basin. The issues identified, in priority order, were water quality, reduction in dry season flows, sedimentation, fisheries decline, wetland degradation, and flooding. An analysis of the avail...

Variation and shift in the seasonal pattern of the hydro-climatic factors is probably because of climate related changes. Rainfall, river inflow, snowmelt, and consequent fluctuation in water level are the hydro-climatic factors that influence the inland fisheries production worldwide. Increase in rainfall and water level favours the reproduction, recruitment and immigration of fish in the inla...

Catch curves have been used to estimate survival and instantaneous mortality for fish and wildlife populations for many years. In order to better analyze catch curve data from the Apostle Islands population lake trout Salvelinus namaycush in Lake Superior, we develop a Bayesian approach to catch curve analysis. First, the proposed Bayesian approach is illustrated for a single catch curve and th...

Between 2014 and 2016, five cases of ciguatera fish poisoning (CFP), involving twenty four individuals, were linked to Spanish Mackerel (Scomberomorus commerson) caught in the coastal waters of the state of New South Wales (NSW) on the east coast of Australia. Previously, documented cases of CFP in NSW were few, and primarily linked to fish imported from other regions. Since 2015, thirteen indi...

Historical perspectives on fisheries and related human behaviour provide valuable information on fishery resources and their exploitation, helping to more appropriately set management targets and determine relevant reference levels. In this study we analyse historical fisheries and fish trade at the north-eastern Baltic Sea coast in the late 17th century. Local consumption and export together a...

By-catch is considered a significant problem in large-scale fisheries yet in small-scale fisheries (SSF), employing >99% of the world’s fishers, there is limited quantitative understanding of by-catch, and catches in general. We provide an assessment of by-catch from fishing gears (fyke, trawl, set trammel, and drift trammel nets) commonly used in small-scale fisheries across the globe, using a...

As the WFD requires carrying out regular quality assessment of fish population, in the frame of this study sampling was done in 3 sites along Lumebardhi i Pejes river. A list of species composition is completed. Altogether 9 fish species and lamprey (Eudontomyzon stankokaramani) were present in catch. The classification of the ecological status is done by using EFI index. The Lumebardhi i Pejes...
