This effect has also been documented in Mediterranean trawl fisheries. In contrast, no information is available with regard to the effect of increasing mesh number in the circumference of square-me...

a number of studies have attempted to demonstrate the antibacterial properties of skin mucus from different species of fish such as turbot, atlantic salmon, rainbow trout, gold fish, seabass, seabream, flounder, barramundi, cichlid and yellowtail . however, most have suffered from alack of definitive data concerning the virulence of the organisms used for in vitro assessment of antibacterial pr...

Seasonal changes in the diel feeding patterns of the zooplanktivorous icefish (Neosalanx taihuensis), which is an endemic species of China, were studied in the large, shallow eutrophic Lake Chaohu of China during the autumn of 2002 and summer of 2003. The results of the diel feeding rhythm indicate that icefish is a visual particulate feeder. There were large differences in diet composition and...
