effects of using n-3 hufa-enriched artemia and non-enriched artemia as the starter food for growth and survival of rainbow trout larvae compared to commercial concentrated food were investigated in this study. the larvae with average weight of 92.9 mg were fed for 20 days with four food treatments included of commercial concentrated food, newly hatched artemia, enriched artemia, and mixture of ...

In this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) Chironomid larvae were examined. For this purpose, 2.5 grams of food per Coconut considered in the period, with three replicates and Chironomid larvae during the period of 15 days in plastic pans were kept in nutrition. The results ...

An appropriate stocking density is beneficial to run an efficient business and improve animal welfare. In most traditional livestock this defined as the number of animals per area. However, larvae mealworm (Tenebrio molitor), one important commercial insects, live both on top inside their feed. study we assessed if different areal densities (2D, range 0.6-10.4 larvae/cm 2 ) resulted in a growth...

Lumpfish ( Cyclopterus lumpus ) serves an important role as cleaner fish for removing salmon lice in aquaculture. For this use, cultivated lumpfish are preferred over wild-caught to avoid overexploitation of natural stocks and provide a stable production good quality eggs larvae. To support this, high containing the necessary building blocks fertilization success, development into normal embryo...

 Post larvae of wild and cultured spawners of the Indian white shrimp (Penaeus indicus, Milne Edwards, 1837) were reared to market size, in commercial ponds of shrimp farming site of Helleh, in Bushehr Province, during a six months period. Environmental factors, management process and the diet used to feed shrimps were almost similar for both treatments. Averages of the weight, length, specific...

normal 0 false false false en-us x-none ar-sa background: dry weight (dw) is an important concept related to patients undergoing hemodialysis. conventional method seems to be time consuming and operator dependent. bio impedance analysis (bia) is a new and simple method reported to be an accurate way for estimating dw. in this study, we aimed to compare the conventional estimation of dw with mea...

abstract coontail (ceratophyllum demersum) and watermilfoil (myriophyllum spicatum) are current submersed weeds in many fresh waters of iran. the excessive growth of these plants causes the reduction in utilization of water resources and making some ecological and economical damages in these areas. the aim of this study was to determine the response of two submerged aquatic weeds of coontail an...
