(Universidad Estatal a Distancia de Costa Rica, 2019)
Apparent metabolizable energy values of n-6 and n-3 rich lipid sources for laying hens
(2019-01-01)
The objective of this research was to evaluate the nitrogen-corrected apparent metabolizable energy (AMEn) balance of the following lipid sources: soybean oil, sunflower oil, linseed oil, and fish oil. Two hundred eighty ...
Physiological responses of Nile tilapia, Oreochromis niloticus, fed vitamin C- and lipid-supplemented diets and submitted to low-temperature stress
(Blackwell Publishing, 2007-06-01)
Water temperature alterations can determine harmful physiological modifications in fish, which should be prepared to cope with this, and nutrition strategies seem to be essential. This study evaluated the effects of different ...

Veligers of the invasive bivalve Limnoperna fortunei in the diet of indigenous fish larvae in a eutrophic subtropical reservoir
(Wiley Blackwell Publishing, Inc, 2017-11)
Larval fish development depends largely on their ability to capture and ingest food items, and on food availability. In this context, invasive species, eutrophication and river impoundments have complex impacts on fish ...
Diet and feeding activity of Acestrorhynchus lacustris (Lütken, 1875) (Characiformes, Acestrorhynchidae) in the water reservoir at Ribeirão Claro, SP

Do cage fish farms promote interference in the trophic niche of wild fish in neotropical reservoir?
(2022-04-01)
Cage fish farming in hydroelectric reservoirs has been reported to promote variations in environmental conditions, which directly interfere with the foraging behavior of wild fish. We have hypothesized that the abundance ...
Generalist populations formed by generalist individuals: A case of study on the feeding habits of a neotropical stream fishPopulações generalistas formadas por indivíduos generalistas: Um caso de estudo sobre os hábitos alimentares de um peixe de riacho neotropical
(2021-01-01)
Aim: We described the diet of the generalist stream fish Knodus chapadae and we tested if the environmental conditions are associated with population’s diet and individual specialization. Methods: We analyzed the stomach ...

Acid and fermented silage characterization and determination of apparent digestibility coefficient of crude protein for pacu Piaractus mesopotamicus
(2002-05-08)
Three types of raw materials including commercial waste from saltwater (SW), freshwater fish (FW) and tilapia fillet residue (FR) were used to produce fish silage by either acid digestion (2% formic acid and 2% sulfuric ...
