“…This conforms to the work of Abdullahi and Abolude (2001) that studied nutrient levels of Bagridae in relation to season from Nigeria. The study also conforms to the work of Abdullahi (2002) Dawson (1980);Craig (1977) and Shulman, (1984); in various temperate fishes and Abdullahi (2002) in Nigeria. Most fishes breed during the wet season, therefore the high content of fat and protein in the species were attributed to their utilization for gonad development, hormonal changes, egg developing and subsequent breeding activities.…”

Proximate compositions of five economically-important fish species from Lake Victoria and Lake Tanganyika, Tanzania were determined using standard methods and procedures of the Association of the Analytical Chemists. Samples of Lates niloticus, Oreochromis niloticus, Rastrineobola argentea, Limnothrissa miodon and Stolothrissa tanganicae were collected during the dry and rainy seasons (December 2012 to March 2013) and (June to September, 2013). Protein contents (17.35-21.44 g/100 g) were significantly (p<0.05) higher in wet seasons and lower (16.13 -19.77 g/100 g) during the dry season in all the species. Similarly, lipids contents were significantly (p<0.05) higher during the wet seasons (1.01 -3.19 g/100 g) and lower (0.79 -1.79 g/100 g) during the dry season in all the species, while carbohydrate (1.89 -4.46 g/100 g) was significantly (p<0.05) higher during the dry season in all the species. The present study showed that these species are good sources of protein in desirable quantities for normal growth, development and as a remedy to nutritional and health related problems. High contents of protein and lipid during wet season make the fish species desirable for consumption during this period. These fish species are therefore recommended to diabetic consumers due to their low carbohydrate contents.

“…Carbohydrates contribute only 0.1%-2.4% (Craig, 1977;Jonsson et al, 1997;Reynolds and Kunz, 2001). Therefore, protein was determined as the mass difference between the fat-free samples and the ash after combustion (12 h at 5508C).…”

The fat and protein content, and thus energy resources of young (parr) Atlantic salmon (Salmo salar) were examined in a temperate river. Juvenile salmon exhibited distinct seasonal patterns of energy storage and use. The lowest levels of energy were found towards the end of winter (mean mass specific energy about 4.3 kJÁg À1). There was a rapid accumulation of fat in spring/ early summer in spite of low-water temperatures (highest mean content of mass specific energy of about 5.0 kJÁg À1 in June). By early autumn (August) there was a rapid depletion of fat and energy resources. The decline in specific energy during late summer was of the same magnitude as the corresponding winter decline. Furthermore, total fat and protein content, and thus energy resources of juveniles below a hydroelectric power plant (hydrostation (HS)) differed from those at a (lower) reference station (RS). The younger fish exhibited higher gains, but also larger losses of energy resources compared to corresponding values at the RS. Specifically during the summer, young of year (YOY) had 31% lower total energy content at the regulated site (mean 1.27 kJ per individual) than the RS (mean 1.84 kJ). Higher mortality may occur at the site most affected by the hydroelectric plant, where energy resources on average were higher, but where depletion was also most severe.

“…Storage level in females and the efficiency of its allocation for gonad maturation will be determining for reproductive success (Watanabe 1985, Rainuzzo et al 1997, Adams 1998. Many works highlight a strong increase in body fats after spawning corresponding to the reconstitution of energy reserves, especially in the form of lipids (Nikolsky 1963, Craig 1977, Penczak et al 1978, Allen & Wootton 1982, Parent et al 1991. Lipid levels are directly related to the food ingested (quantity and/or quality) and constitute a good index for estimating fish conditions (Elliott 1976, Penczak et al 1977, Dos Santos et al 1993.…”
