Mudanças ontogenéticas na dieta de Oreochromis niloticus and Tilapia rendalli da represa de Barra Bonita (rio Tietê, Estado de São Paulo, Brasil)
(2012-07-11)
The Nile Tilapia, Oreochromis niloticus, and the Congo Tilapia, Tilapia rendalli, are important members of the African cichlids, and have been introduced to many Brazilian lakes and reservoirs. These species exhibit a large ...
Partial molecular characterization of the Nile tilapia (Oreochromis niloticus) alpha-cardiac muscle actin gene and its relationship to actin isoforms of other fish species
(Sociedade Brasileira de Genética, 2007-01-01)
An alpha actin gene segment, isolated from Nile tilapia (Oreochromis niloticus), was characterized by nucleotide sequencing, predicted amino acid sequence and Southern blot hybridization. Genomic DNA amplification resulted ...
HETEROGENEOUS GROWTH IN THE NILE TILAPIA - SOCIAL STRESS AND CARBOHYDRATE-METABOLISM
(Elsevier B.V., 1993-08-01)
Increase in heterogeneous growth as a result of grouping in the Nile tilapia, Oreochromis niloticus (L.), is presumed to be partially promoted by the social stress imposed by the dominant fish on the subordinates. Such ...
Paratrichodina africana (Ciliophora): A pathogenic gill parasite in farmed Nile tilapia
(2013-10-08)
Trichodinids are ciliated protozoa that are widely known as one of the main groups of fish parasites. The genus Trichodina presents the greatest species diversity. However, records of Paratrichodina species are scarce, and ...
Growth performance of Nile tilapia, Oreochromis niloticus, fed diets containing levels of pyridoxine and haematological response under heat stress
(Wiley-Blackwell, 2012-07-01)
In order to assess the effect of dietary pyridoxine supplementation on the growth performance of Nile tilapia and the haematological response under heat stress, 192 fingerlings (8.41 +/- 0.22 g) were randomly distributed ...
Digestibilidade Aparente e Efeito Macro-Microscópico em Tilápia do Nilo (Oreochromis niloticus) Arraçoadas com Torta de Dendê
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 1998-03-01)
To evaluate the nutritional value of palm kernel meal on the performance Nile tilapia (Oreochromis niloticus), five isonitrogenous (30% crude protein), isoenergetic (2800 kcal/kg of digestible energy), and isofibrous (10% ...
Energia digestível para larvas de tilápia-do-nilo (oreochromis niloticus) na fase de reversão sexual
(2005-11-01)
This experiment was conducted to evaluate different levels of digestible energy on the performance of Nile tilapia larvae (Oreochromis niloticus) during the sexual reversion phase. Three hundred and seventy-five larvae ...
Dietary α-tocopheryl acetate on fillet quality of tilapia
(2009-12-01)
This work compared the effects of dietary α-tocopheryl acetate on storage life of tilapia fillets. Three experimental diets containing increasing a-tocopherol levels (zero, 100, and 200 mg kg-1) were used. The fish, with ...
Aggressive behaviour traits predict physiological stress responses in Nile tilapia (Oreochromis niloticus)
(Taylor & Francis Ltd, 2009-03-01)
This study tested whether aggressive behaviour can predict individual variation in stress responses of Nile tilapia Oreochromis niloticus. We used a mirror test to measure tendency to aggressive behaviour, and calculated ...
Time-place learning in food-restricted Nile tilapia
(Elsevier B.V., 2008-01-01)
Time-place learning based on food association was investigated in eight food-restricted Nile tilapias. Each fish was individually housed for 10 days in an experimental tank for adjustments to laboratory conditions, and fed ...
