Social Behavior and Welfare in Nile Tilapia [PDF]

Fishes, 2019
Fish social behavior can be affected by artificial environments, particularly by factors that act upon species that show aggressive behavior to set social rank hierarchy. Although aggressive interactions are part of the natural behavior in fish, if constant and intense, such interactions can cause severe body injuries, increase energy expenditure, and ...

Emerging fish pathogens Lactococcus petauri and L. garvieae in Nile tilapia (Oreochromis niloticus) farmed in Brazil

bioRxiv, 2022
Lactococcosis in fish has been associated with Lactococcus garvieae and the recently described L. petauri. However, the relevance of these emerging fish pathogens to Nile tilapia still requires thorough understanding.

Chitin digestibility and intestinal exochitinase activity in Nile tilapia and rainbow trout fed different black soldier fly larvae meal size fractions

Aquaculture Research, 2022
Black soldier fly ( Hermetia illucens ) larvae meal (BSFLM) is a novel fish feed ingredient with a high crude protein content ( ~ 40% dry matter, DM). However, BSFLM also con - tains chitin, which might impair nutrient digestibility.

Ontogeny in the visual system of Nile tilapia [PDF]

Journal of Experimental Biology, 2012
SUMMARYRetinal neurogenesis in fish facilitates cellular rearrangement throughout ontogeny, potentially allowing for optimization of the visual system to shifts in habitat and behaviour. To test this possibility, we studied the developmental trajectory of the photopic visual process in the Nile tilapia.

Impacts of Fortifying Nile Tilapia (Oreochromis niloticus) Diet with Different Strains of Microalgae on Its Performance, Fillet Quality and Disease Resistance to Aeromonas hydrophila Considering the Interplay between Antioxidant and Inflammatory Response

Antioxidants, 2022
The oxidative stress facing fish during intensive production brings about diseases and mortalities that negatively influence their performance. Along with that, the increased awareness of omega-3 polyunsaturated fatty acids (omega-3-PUFAs) health ...

Digestibility of Insect Meals for Nile Tilapia Fingerlings [PDF]

Animals, 2019
Insects are a valuable source of nutrients for fish, but little is known about their nutritional value for Nile tilapia fingerlings. To evaluate the nutritional value and energy apparent digestibility coefficient (ADC) of five insects for Nile Tilapia male fingerlings, 900 fish were distributed in 18 fiberglass conic tanks, in a completely randomized ...
