The study evaluated to model the growth and reproduction aspects of the hake, Merluccius merluccius, in the Sea of Marmara. On-board sampling was conducted on the commercial beam trawl fishery from February 2016 to January 2017. For the growth trajectories, using monthly length frequency data set, different methods were employed to improve parameter optimization. The variation of reproductive i...

in western canada, durum wheat cultivars (triticum durum) have low to moderate lev-els of seed dormancy and are susceptible to pre-harvest sprouting. the aim of this study was to evaluate the dormancy level of canadian durum wheat cultivars and to identify tetraploid wheat accessions with elevated levels of seed dormancy. first, the level of seed dormancy and length of after-ripening of 17 nort...

three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in finike bay for red mullet (mullus barbatus l., 1758). the sampling program was arranged during february to may 2012. holt (1963) method was used for selectivity of trammel nets. red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...

Pedigree selection was practiced on two bread wheat populations, namely Debeira x Sahel 1 and Sids 6 x Sahel 1as a first and second population, respectively under drought stress conditions (at 12 % soil moisture content) in order to improve some morphological traits (plant height, spike length, no. of spikelets /spike and days to maturity). The obtained results revealed that all F3 families in ...

An economically important species of Citharus linguatula was investigated in the Sea Marmara (Eastern Mediterranean, Turkey). Length-weight relationships, growth parameters, reproductive time, and first sexual maturity length were determined. A total 236 individuals analyzed, weight varied from 7.5 to 26.5 cm TL (17.11±3.62 cm) 2.67 180.81 g (44.07±1.84 g), respectively. The length-weight relat...

This work presents information regarding the biology and state of conservation of an endangered annual fish Hypsolebias antenori. Fish were captured from small seasonal pools located in Northeastern Brazil. The total body length, body mass, sex ratio, first sexual maturity were investigated. The sampled population showed sexual dimorphism. There was a predominance of females (60%) over males (4...

The aim of the research was to investigate the effects of divergent selection on some production and clutch traits in Japanese quail (Coturnix coturnix japonica). Over 5 generations divergently selected two Japanese quail lines (HBW: High Body Weight and LBW: Low Body Weight) and control line (C) that derivate from a base random bred population were used in this study. Weight of first egg, age ...
