Fish intake and serum fatty acid profiles from freshwater fish.
BACKGROUND Although high mercury concentrations in fish diets raise an alarm, fish can also be a healthy choice because it is the primary source of n-3 fatty acids (FAs). However, little information is available on the contribution of freshwater fish to serum FA concentrations. OBJECTIVE This study examined the FA pathway from fish to serum in 243 moderate consumers of freshwater fish. DESI...
متن کاملStudy and determination of fatty acid composition of some commercially important freshwater fish
Fatty acid composition of fish is one of the key factors for the evaluation of fish nutritional value and it could be different based on fish species, habitat, nutrition and etc. The aim of the present study was to evaluate the fatty acid composition of five commercially important freshwater fish from the fish market. Studied fish were as follows: Barbell, Luciobarbus pectoralis (Heckel, 1843),...

Cross-cultural comparisons of categorization often confound cultural factors with expertise. This paper reports four experiments on the conceptual behavior of Native American and majority-culture fish experts. The two groups live in the same general area and engage in essentially the same set of fishing-related behaviors. Nonetheless, cultural differences were consistently observed. Majority-cu...
متن کاملBehavioural thermoregulation in two freshwater fish species.
In the presence of a vertical thermal gradient, juvenile three-spined sticklebacks Gasterosteus aculeatus and minnows Phoxinus phoxinus positioned themselves higher in the water column compared with adult conspecifics. This result was consistent regardless of whether age cohorts were tested separately or together. Furthermore, juveniles but not adult fishes positioned themselves higher in water...
متن کاملForests fuel fish growth in freshwater deltas
Aquatic ecosystems are fuelled by biogeochemical inputs from surrounding lands and within-lake primary production. Disturbances that change these inputs may affect how aquatic ecosystems function and deliver services vital to humans. Here we test, using a forest cover gradient across eight separate catchments, whether disturbances that remove terrestrial biomass lower organic matter inputs into...
