compensatory growth response and body composition of male sailfin molly, poecilia latipinna subjected to short-term starvation and subsequent feeding were studied for 54 days. four feeding schedules were used in this study: c, control (were fed to apparent satiation throughout the experiment); t1, treatment 1 (3 days starvation and 6 days refeeding); t2, treatment 2 (6 days starvation and 12 da...

One strategy for estimating total catch is to employ two separate surveys that independently estimate total fishing effort and catch rate with the estimator for total catch formed by their product. Survey designs for estimating catch rate often involve interviewing the fishermen during their fishing episodes. Such roving designs result in incomplete episode data and characteristically have empl...

Catch is a mechanical state occurring in some invertebrate smooth muscles characterized by high force maintenance and resistance to stretch during extremely slow relaxation. During catch, intracellular calcium is near basal concentration and myosin crossbridge cyctng rate is extremely slow. Catch force is relaxed by a protein kinase A-mediated phosphorylation of sites near the N- and C- temini ...

Baltic seals are recovering after a population decline. The increasing seal stocks cause notable damage to fisheries in the Baltic Sea, with an unknown number of seals drowning in fishing gear every year. Thus, sustainable seal management requires updated knowledge of the by-catch of seals--the number of specimens that die in fishing gear. We analyse the by-catch of grey seals (Halichoerus gryp...

The shrimp fishery is the most economically important fishery in Mexico. The trawler-based portion of this fishery results in high rates of by-catch. This study quantifies and describes the biodiversity of by-catch associated with trawling in the Bahía de Kino region of Sonora, Mexico. Data were collected from 55 trawls, on six boats, over 14 nights, during November of 2003, 2004, 2006-2009. By...

The relationship between annual water level of Danube and annual catches of Pontic shad (Alosa immaculata, Bennett 1835) in Romania were analyzed. For analysis of long term data on the Danube water level and Pontic shad catch (1920-2013), combinations of different methods were applied using programs Statistica, SPSS 13.0 and MATLAB 6. Periodograms, containing cyclic patterns, were obtained usin...

the gobies are non-commercial fishes in the iranian waters of the caspian sea for which population dynamics and stock status are poorly known. in this survey, we tried to define species diversity and catch per unit effort (cpue) of gobiidae by using beach seine nets in salmanshahr, the southern caspian sea. from march 2011 to april 2012, 224 specimens representing 4 gobiid species, belonging to...
