Size structure, age, and diets of introduced Chinook salmon (Oncorhynchus tshawytscha) inhabiting the Palena River, Chilean Patagonia
(Facultad de Medicina y Ciencia, 2019)
Chinook salmon (Oncorhynchus tshawytscha) were recorded in two extensive areas during a survey conducted between February 2012 and June 2013 to obtain information regarding the seasonal distribution and population structure ...
In vitro assays predicts mineral retention and apparent protein digestibility of different fish feed measured using a juvenile P. mesopotamicus model
(Wiley Blackwell Publishing, Inc, 2018-06)
Feed chemical composition only provides information about nutrient content of a diet, but not its bioavailability. The aims were to determine mineral bioaccessibility and protein digestibility of three different fish feed, ...
Intraspecific host selection by kleptoparasitic Kelp Gulls in Patagonia
(Waterbird Society, 2001-12)
We studied kleptoparasitic behavior of Kelp Gulls (Larus dominicanus) feeding on fishery waste at trawl vessels in northern Patagonia, Argentina, through experimental discarding of fish. Intraspecific kleptoparasitism ...
FAAS determination of metal nutrients in fish feed after ultrasound extraction
(Elsevier B.V., 2009-03-15)
This paper proposes a method to determine calcium, magnesium, manganese and zinc in fish feed samples using ultrasound in the analyte extraction process, and subsequent quantification by flame atomic absorption spectrometry ...

The effect of high rearing densities on the growth of juveniles of the cichlid, cichlasoma managuense
(Universidad Nacional, Costa Rica, 1992-01-01)
The effect of high density culture on the growth of juvenile jaguar cichlids was investigated. Mean growth rate decreased with density, while the growth rate of the largest fishes was not affected. Reduction in mean growth ...
Growth performance of Colossoma macropomum (Cuvier) juveniles at different feed rations
(Wiley & Sons, 1992)
Growth performance, feed utilization and changes in body composition of Colossoma
macropomum (Cuvier) juveniles — in the weight range 2 to 200 g — fed an artificial high protein
diet, have been analysed against feed ...
Digestible protein requirements and muscle growth in juvenile tambaqui (Colossoma macropomum)
(2019-06-01)
Several investigations have been carried out to improve the productivity of tambaqui, an economically important fish species in Brazil and other Latin American countries. This study determined the digestible protein (DP) ...
Formation of ring marks in stocked tilapia juveniles (Oreochromis aureus/O. niloticus) (Perciformes: Cichlidae)
(Universidad de Costa Rica, 2007)
