The population biomass, fishing mortality dynamics and reference points of the rational exploitation Black-Azov sea shad during period 2004-2020 were evaluated using JABBA surplus production model in “catch-only” version. IUU estimation preliminary parametrization by CMSY was performed to improve assessment accuracy. According output, stock biomass interval 1315-1341 t, range 0,03-0,38. During ...
Diadromous species act as nutrient vectors between their marine and freshwater habitats. Few valuations of this regulating service exist none at the scale distribution ranges. This large-scale approach seems particularly relevant for moving exchanging individuals across borders territories these populations may strongly depend upon each other in terms population viability provision ecosystem se...
Abstract Development of a blue economy is firmly embedded in the development plans Bangladesh. Advances freshwater aquaculture have promoted Bangladesh to fifth largest fish producer world. However, marine resource base Bangladesh, which now even greater following recent settling disputes regarding maritime boundaries with neighbouring countries, lends itself aquaculture—known as mariculture. S...
Abstract The timing of entry into freshwater by mature anadromous fishes is an important component their migration phenology. In iteroparous species, identifying the cues that influence freshwater, and annual variability in these timings, assessing extent individual repeatability. Here, passive acoustic telemetry tracked 71 twaite shad Alosa fallax (‘shad’) returning to River Severn’s upper est...
Carbonic anhydrase-8 gene therapy inhibits the ITPR1-cytosolic free calcium pathway producing analgesia and anti-hyperalgesia Roy C Levitt, Gerald Z Zhuang, Benjamin Keeler, Jeff Grant, Laura Bianchi, Eugene S Fu, Yan Ping Zhang, Diana M Erasso, Jian Guo Cui, Tim Wiltshire, Qiongzhen Li, Shuanglin Hao, Konstantinos D Sarantopoulos, Keith Candiotti, Shad B Smith, William Maixner, Luda Diatchenko...
The ecological features of invasive alien species are crucial for their effective management. However, they often lacking in newly invaded ecosystems. This is the case European catfish Silurus glanis L. Lake Maggiore, where present since 1990, but no scientific information available on its ecology. To start filling this knowledge gap, 236 (67 cm to 150 total length) were collected, measured, an...
