The rapid growth of aquaculture in recent times has been exemplified by increases in growth, survival and nutrition efficiency through feeding, and these are among important objectives in the aquaculture industry. The use of probiotics is one effective way to improve the diet of fishes. The aim of this study was to investigate the effects of probiotic Bactocell on growth parameters and survival of benni fish (Mesopotamichthys sharpeyi) fingerlings. Two hundred and forty (240) fish with the similar weight were divided into the four experimental groups (0, 0.1, 0.2 and 0.3 grams of probiotic Bactocell per kg of diet). Fish were fed twice per day up to satiation for 8-week period. Fish were weighed at the end of trial period. The results showed that probiotic Bactocell had positive effect on some growth parameters of benni. At the end of trial period, the experimental groups treated by probiotic showed higher final weights compared to control but not statistically significant (p > 0.05). Percent weight gain and specific growth rate in the second treatment (0.2 g probiotic Bactocell per kg of diet) significantly increased compared to control (p < 0.05). The feed conversion ratio decreased in treated groups (0.1, 0.2 and 0.3 g probiotic bactocell per kg of diet) compared to control but not statistically significant (p > 0.05). Also, the survival rate showed no noticeable effects (p > 0.05). It is proposed that probiotic Bactocell (0.2 g per kg of diet) when incorporated in diet can improve the growth and nutrition efficiency of benni fish fingerlings. © 2015, BIOFLUX SRL.

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.

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.

In our approach to homologate the first Romanian rabbit breed, Transylvanian Giant Rabbit (TGR), we undertook a series of research to highlight the breed morphological, productive and reproductive features. Thereby regarding morphological traits, results showed 3.64±0.03 cm hair length, 55.03±0.48 cm body length, 15.97±0.15 cm ear length, and an average of 6.44±53.74 kg body weight. Regarding the correlation coefficients upon the corporal traits strongly positive correlations were found (0.858) between ear length and body weight, and between body length and body weight (0.865). Correlations between hair and ear length (0.050), and between hair length and body weight (0.054) were positive but at low value. The only negative correlation was found between hair length and body length (-0.120). Following the reproductive traits TGR showed a prolificacy of 7.56±0.52 kits/female, a number of 7.06±0.17 weaned individuals/female and an average of 1788.75±40.12g weight at weaning (weaned at 8 weeks of age). The productive traits of the breed were highlighted by the body weight evolution and the average daily weight gain (DWG) between the age of 1 and 8 months. At the age of 1 month the average weigth was 722.45±7.94g, at the age of 2 months 1880.88±8.53g, at the age of 3 months 2944.18±6.18g, at the age of 8 months attaining 6443.94±53.74g. The highest DWG was obtained at the interval of 1-2 months (38.61g), and the lowest at 7-8 months (6.56g). The morphometric statistics shows that this new rabbit strain is already genetically consolidated and the analyzed reproductive and productive traits recommend it as a competitive production breed. © NwjZ, Oradea, Romania, 2014.

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.

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.

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.

The current paper presents the preference of the Romanian customers (aquarium hobbyists) for different freshwater aquarium fish based on survey data, as well as statistics collected from the Romanian hatcheries, import-export companies, intermediary companies, and small and occasional merchants during 2000-2010. Twenty of the most important companies and producers in Transylvania (Romania) were considered in the statistics. Results showed that the top three most popular fish in Transylvania were comprised of the guppy (Poecilia reticulata, 18.2%), neon tetras (Paracheirodon innessi, 17.4%) and platyfish and swordtails (Xiphophorus superspecies, 9.8%). At the family level, the most popular aquarium fish were Poeciliidae (36.2%), Characidae (28.1%), Cyprinidae (11.4%) and Anabantidae/Belontiidae (7.6%). © NwjZ, Oradea, Romania, 2013.
