This study characterized the fishery dynamics of blue whiting, a bycatch species bottom trawl Norway lobster fishery, in NW Mediterranean. Landings and effort data over last two decades were combined with current information on spatial distribution catch, size age structure whiting year. Recruitment to demersal habitat occurred from 5 cm total length (TL) shelf break spring (April-May), when di...
We examined the temporal trend in mean trophic level (mTL), trophic category landing (TrC) and landing profile (LP) of the exploited marine community (49 species) in the fishing zone of Hormozgan (north of Persian Gulf and Oman Sea) from 2001 to 2011. LP had an increasing trend (r = 0.88, P<0.001), whereas, mTL of the landings showed a significant decrease from 2001 to 2011 (r = -0.69, P<0.05)....
The interactions between rocket exhaust plumes and the surface of extraterrestrial bodies during spacecraft landings involve complex multiphase flow dynamics that pose significant risk to space exploration missions. two-phase is characterized by high Reynolds Mach number conditions with particle concentrations ranging from dilute close-packing. Low atmospheric pressure gravity typically encount...
The purpose of the study was to provide up-to-date information on inland fisheries landings in Basrah province, Iraq. During 2020-2021, species composition, and total landings, trends at six landing locations research region were assessed. There seven cyprinids, three cichlids, mullet, two sparids silurids. foreign C. carpio, tilapias species, auratus dominated accounting for 44.2% entire catch...
The impact of hydrological regimes on the productivity in lake ecosystems has received considerable attention recent decades. This study tested hypothesis that water level fluctuations influence fisheries Lake Van. Monthly data from 2000 to 2014 were obtained Hydroweb and corresponding same time period acquired Turkish Statistical Institute. In order test whether demonstrated significant concor...
Mean trophic level (MTL) of landings and primary production required (PPR) by fisheries are increasingly used in the assessment of sustainability in fisheries. However, in their present form, MTL and PPR are prone to misinterpretation. We show that it is important to account for actual catch data, define an appropriate historical and spatial domain, and carefully consider the effects of fisheri...
The red shrimp, Aristeus antennatus (Risso, 1816), is one of the most important resources for the bottom-trawl fleets in the northwestern Mediterranean, in terms of both landings and economic value (Demestre and Lleonart, 1993; Demestre and Martin, 1993; Maynou et al., 2006). One of the ports obtaining the highest yields in the area is that of Blanes (Irazola et al., 1996; Bas, SCIENTIA MARINA ...
