Artemia Fed With The High Energy Diet Case Study
Artemia fed with the high energy diet had a significantly higher length-specific O2 consumption rate on average than that of the Artemia fed with the low energy diet (t=-5.18, df=18, p=0.0000314) (Figure 1).
Furthermore, the proportion of gravid females in the group of Artemia fed with the high energy diet was significantly larger than that of the group fed with the low energy diet (t=-5.73, df=21, p=0.00000543)
The results acquired support the hypothesis in that the Artemia who were fed the high protein-based diet showed greater rates of fecundity and oxygen consumption than the Artemia who were fed the low protein-based diet. The percentage of gravid females was used as an indicator for fecundity and the overall length-specific oxygen consumption demonstrated metabolic rates. This striking result can be explained by the “protein leverage hypothesis”, as the Artemia fed on the low energy diet went through a level of starvation and overindulged on other macronutrients. This would mean they were not fed enough protein, and therefore their metabolic processes slowed down, not allowing them to function …show more content…
This is seen in the study performed on guppies, where guppies who were fed 47% protein showed significantly higher values of ovarian length, as well as gonad width and weight, than the guppies who were fed 15% protein (Dahlgren 1980). It is also seen elderly women aged 65-67, who were fed a high protein diet that eventually positively associated with bone mineral density, which may assist in the prevention of osteoporosis and bone loss (Rapuri et al. 2003). Our study fortunately agrees with that of Fábregas et al. (1996) where Artemia Franciscana (Artemia) fed with a higher concentration of nutrients had a larger percentage of gravid females than the Artemia fed on a lower nutrient based-diet (Fábregas et al.
