The aim of this study was to determine the selectivity of monofilament gillnets with different mesh size for silver crucian carp in Eğirdir Lake. In this study, it was investigated that the selectivity of monofilament gillnets with nominal mesh size (stretched) with 32, 40, 50, 60, 70, 80, 90 mm and trammel nets with 100, 110, 120, 130, 140, 150 mm for catching of silver crucian carp.

In developed countries, children with intrauterine growth restriction (IUGR) or born preterm (PT) tend to achieve catch-up growth. There is little information about height catch-up in developing countries and about height catch-down in both developed and developing countries. We studied the effect of IUGR and PT birth on height catch-up and catch-down growth of children from two cohorts of live...

This study reports on the development of a portable iodine-stabilized 543 nm sgreend length-standard laser, which is low cost and robust. All the needed optics and electronics were integrated into one box which measured 36 cm in length, 30 cm in width, and 15 cm in height. Simple circuits for third harmonic locking are presented and the laser’s frequency instability could be as small as 2310−12...

present study describes the length-weight (lwr) and length-length (llr) relationships of a freshwater catfish eutropiichthyes vacha hamilton from indus river, sindh, pakistan. a total of 281 specimen of e. vacha were collected from fisherman?s catch from february 2005 to january 2006, are used for this study. the parameters a and b of the length-weight relationship were calculated as w= alb are...

Effective factors of tori-poles in reducing incidental catch of albatross were examined with the data from Japanese observer program in southern bluefin tuna fishery. A total of 727 observations were used in the analysis. The data in night settings were not used because observed numbers of albatross and other seabirds were not recorded correctly during night-setting. The tori-pole specification...
