Many aquarists, fish or rabbit breeders have at their disposal for reproduction heterogenic populations as a result of segregation, or due to crossbreeding. In many cases, they must buy new brood stock every 2-3 years due to the fact their old brood stock degenerates visible after several generations. The aim of this paper is to underline that there are some low cost and easy to understand principles available with application in animal improvement and production. Color, size and shape are important traits when we describe a product as a phenotypically uniform line, strain or breed, e.g. the albino African catfish, the red eyed swordtail, the Red Blond guppy, the large chinchilla rabbit, the New Zealand white rabbit. A standardized color, shape and size describe better an animal population and thus the said product is promoted better on the market. Two simple examples of applications will be presented in this paper, the case of purification and maintaining of thermo-resistant guppy fish, and the principle of improvement of body size and maintaining the color pattern in Transylvanian Giant rabbit. The key to success is to know what is (are) the recessive gene(s) for every relevant locus.

Concepts of Integrated Water Resources and River Basins Management are considered as key points to the question of how conflict can be avoided and international waters be managed. Over the last fifty years, countries have been engaged in more than 500 conflictive events over water. Almost 90% were disagreements over infrastructure and water quantity allocation. The Convention on the Nonnavigational Uses of International Watercourses (1997) provides an important template for cooperation and equitable transboundary water-sharing.

Humans kept ornamental fish in their homes from ancient times. During time, the ornamental fish industry became a profitable enterprise. Color, size and shape are important traits when we describe a fish as a phenotypically uniform line, strain or breed; a standardized color, shape and size describe better a fish population and thus it is promoted better on the market. Several varieties of fish are being artificially colored to improve marketability. Painted, dyed or tattooed fish are terms for a new variety of pet fish whose scales have been transformed from monochrome silver into vivid pigmentations using artificial colors or lasers. These practices produce many health problems for fish. We should not to put money above the life and welfare of any living thing. Education of the customers is a very important thing, because artificially colored fish continue to exist because of demand. © 2015, BIOFLUX SRL. All rights reserved.

Ornamental fish were kept in captivity from ancient times. Gradually, the ornamental fish industry became a profitable enterprise. Color, size and shape are important traits when we describe a fish as a phenotypically uniform line, strain or breed. Numerous varieties of aquarium fish have been artificially modified regarding their body shape or coloration. Several varieties of fish are being artificially colored by painting and tattooing to improve their marketability. All these practices cause many health problems for fish. Education of the customers is a very important thing, because artificially modified fish continue to exist because of demand. © 2015 BIOFLUX SRL. All rights reserved.

The paper reviews a series of results on heavy metal and thermal stress in fishes, published in a large number of papers, most of them being important in the context of conservation, animal production, human and veterinary medicine, pharmaceutics, environmental engineering, or fundamental research (including biochemistry, cell biology, molecular biology, heredity, ethology, ecology, evolution). Understanding the genetic bases of tolerance in living organisms (in this particular case, fishes) to various stressors and continuously changing environments is key to implementing many practical applications. © 2010 Editura Ştiinţificǎ.
