Study on length frequency and catch per unit effort of sturgeon spawners in the fishing grounds of Mazandaran province

 In this study, the catch composition and the catch per unit effort (CPUE) of sturgeon spawners caught by the gill net were investigated in the fishing grounds of Mazandaran province in two regions 3 and. Sampling and data collection of sturgeon spawning fish was done seasonally from 7 fishing grounds using gill nets with a mesh size of 150 mm. The results of the Chi-square test showed that the...

Effect of a light change in conical lift nets on the length and weight composition of Common sprat (Clupeonella caspia, Svetovidov, 1941) from Amirabad fishing port

The research study the effect of changing light color on the length and weight composition of common sprat (C. caspia) catch in conical lift net with a mesh size of 8 mm (knot to knot). For this purpose, in January 2018 the sprat fish caught by three fishing vessels during 30 times of fishing operations at 50-40 m depth in Amirabad fishing port. The results showed that from total number of 2874...

Variation in the Male Pheromones and Mating Success of Wild Caught Drosophila melanogaster

Drosophila melanogaster males express two primary cuticular hydrocarbons (male-predominant hydrocarbons). These act as sex pheromones by influencing female receptivity to mating. The relative quantities of these hydrocarbons vary widely among natural populations and can contribute to variation in mating success. We tested four isofemale lines collected from a wild population to assess the effec...

Potential exposure to PCBs, DDT, and PBDEs from sport-caught fish consumption in relation to breast cancer risk in Wisconsin.

In Wisconsin, consumption of Great Lakes fish is an important source of exposure to polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT), polybrominated diphenyl ethers (PBDEs), and other halogenated hydrocarbons, all of which may act as potential risk factors for breast cancer. We examined the association between sport-caught fish consumption and breast cancer incidence as p...
