2. Effect of replacing fish meal by full fat soybean meal on growth performance, feed utilization and gastrointestinal enzymes in diets for African catfish Clarias gariepinus
Resumo Objetivou-se avaliar o efeito da substituição da farinha de peixe por diferentes níveis de farelo de soja integral (FSI) sobre o crescimento e atividades de enzimas digestivas no estômago, fígado e intestino de Clarias gariepinus. Quatro dietas (D1, D2, D3 e D4) foram formuladas com 0, 15, 20 e 20 g 100-1 proteína + DL-metionina, alternando FSI

3. Gonadosomatic index and some hematological parameters in African catfish Clarias gariepinus (Burchell, 1822) as affected by feed type and temperature level
ABSTRACT The purpose of the current study was to examine the effects of different feeds/nutrients and temperature on the gonadal development of Clarias gariepinus. The gonadosomatic index (GSI) and blood parameters including red blood cell count (RBCs), white blood cell count (WBCs), hemoglobin (Hgb) level, hematocrit (HCT), platelets (PLT) and mean corpuscu

4. Susanlimae ianwhittingtoni gen. nov., sp. nov. (Monogenoidea: Dactylogyridae), a dweller of the gill rakers of Pseudeutropius moolenburghae (Siluriformes: Schilbeidae) from Sumatra
ABSTRACT A new genus and species of Monogenoidea, Susanlimae ianwhittingtoni gen. nov., sp. nov., are proposed for dactylogyrids collected from the "Nuayang tipis", Pseudeutropius moolenburghae Weber & de Beaufort, 1913, which inhabits freshwater in Sumatra. While clearly a member of a putative clade that includes Asian and African catfish parasites, S. ianw

6. Alimentação e impactos da espécie exótica bagre-africano (Clarias gariepinus Burchell,1822) no estuário do rio Itanhém, Bahia / Feeding habits and impact of the alien species African catfish (Clarias gariepinus Burchell, 1822) in Itanhaém River estuary, Bahia.
This work was developed in order to investigate the impact of the alien species Clarias gariepinus in the Itanhém River comparing to the adjacent Caravelas River, where this species does not occur. A total of 214 stomachs from C. gariepinus, Centropomus undecimalis, C. parallelus were analyzed. In Caravelas River, Brachyura was the main food item for C. par

7. The introduction of the African catfish Clarias gariepinus (Burchell, 1822) into Brazilian inland waters: a growing threat
A biologia de Clarias gariepinus, uma espécie introduzida, foi estudada na lagoa Encantada (Ilhéus, Bahia). As amostras foram obtidas com rede de espera, entre maio de 2002 e fevereiro de 2004. Todos os indivíduos capturados estavam acima do tamanho médio de primeira maturação citado na literatura. A ocorrência de machos e fêmeas em estágio de matur

8. Analise filogenetica da superfamilia Loricarioidea (Teleostei: Siluriformes) com base na ultra-estrutura da espermiogenese e dos espermatozoides / Phylogenetic analysis of superfamily Loricarioidea (Teleostei: Siluriformes) based on spermiogenesis and spermatozoa ultrastructure
The order Siluriformes comprises the most diverse and widely distributed ostariophysan groups, presenting thirty-six families with approximately 480 genera and over 3.000 species. Among the neotropical siluriform lineages likely to be monophyletic is the superfamily Loricarioidea. The relationships among catfish families suggest that Loricarioidea is sister

11. Hepatic regeneration in african catfish (Clarias gariepinus) after partial hepatectomy. / Regeneração hepática em bagre africano (Clarias gariepinus) após hepatectomia parcial.
The liver is an important organ in studies aimed to the verification of animals reactions to chemical injuries. The partial hepatectomy (PH) is one of the methods that are usually employed in hepatic regeneration experiments. Our objectives in this work were to verify the influence of 30% and 70% PH on the hepatic cells proliferation index as it is measured
