In this work, we aimed to determine the indicator of the directional movement of the climbing perch in the water flow (rheoreaction), which helps to identify the features and dynamics of movements and the behavioral response of fish to the different factors.

Objective: This dissertation explores the influence of pectoral fin structures at different swimming modes on a robotic fish's locomotion behavior; Some objectives are addressed to achieve the mentioned aim as follows: Firstly, new designs based on bio-inspired pectoral fin types are constructed. Secondly, to describe fin deformation and body part movement, novel dynamically mathematical models are developed.

Oocyte mitochondria are highly dynamic and exhibit frequent fission and fusion. Those are clustered in the cytoplasm of previtellogenic oocytes which prepare for different synthetic activities for successful reproductive investment. In contrast, mitochondrial abundance is less in the male gametic lineage. The spermatocytes and the nurse cells in the testis have an unusual type of mitochondria, nebenkern which is formed by the fusions of number of mitochondria. A completely different type of mitochondrion is discovered in the flagellum of the spermatozoa.

Ship ballast water is a recognized medium for transfer and introductions of nonindigenous species. There is a need for new ballast water treatment methods that effectively and safely eliminate or greatly minimize movements of these species. The present study employed laboratory methods to evaluate the bactericidal efficacy of increased pH (pH 10.0–12.0) for exposure durations of up to 72 h to kill a variety of Gram-negative and Gram-positive bacteria including fish pathogens (Aeromonasspp., Yersinia ruckeri, Edwardsiella ictaluri, Serratia liquefaciens, Carnobacterium sp.

"There's a railway line that runs from… one side of Qinghai Lake and there's a road that goes to the other side. If you look at the movements of H5N1, they don't seem to tie in with migratory bird routes for the simple reason they seem to follow the Trans-Siberian railway." "Lots of people don't realize that there's movement of poultry from one country to another, even to Nigeria, where we've got bird flu. People are transporting all sorts of poultry meat." (Lyn 2006). There is also a fish farm in the vicinity of Qinghai Lake; in integrated...

We asked Rowett to look ahead to 2020 and to map how the diet changes in line with predicted increases in population. The modelling shows that our diets will not need to change that much from current guidelines if we are to meet the WWF 2020 GHGE targets. We will still be able to eat meat and dairy, crisps and chocolate, for example. The weekly menu contains fish and chips, macaroni cheese, chicken curry and beef chilli, as well as plentiful amounts of fruit and vegetables – so it’s not a mundane menu. This demonstrates that you do not necessarily...

A preliminary study was carried out in mid 1999 on the status and potential impact of the introduction of exotic fish species in the Mekong Basin. Introductions have been made for four main purposes: aquaculture, stocking into lakes and reservoirs, pest control (mosquito) and the aquarium fish trade. Introductions of exotic species and movements of large quantities of fish for stocking are accompanied by risks to the environment, the possibility of native fish species declining through competition, predation or genetic interference, and the possible spread of disease....

Dreams happen during the rapid eye movement (REM) stage of sleep. In a typical night, you dream for a total of 2 hours, broken up by the sleep cycle. Researchers do not know much about how we dream or why. They do know that newborns dream and that depriving rats of REM sleep greatly shortens their lives. Other mammals and birds also have REM sleep stages, but cold-blooded animals such as turtles, lizards and fish do not.Dreams have been a mystery to us since man first developed the ability to walk upright. The stuff of legends, myth and fairy tale,...
