Effect of food quantity and quality on population growth rate and digestive activity in the euryhaline rotifer Brachionus plicatilis Müller

Popis výsledku v původním jazyce

We investigated the nutritional effects of both food quantity and quality on Brachionus plicatilis. We examined population growth rate, reproduction and phosphatase activity (PA) in the homogenate of rotifers fed by nutrient-replete algal food supplied at different quantities. Population growth rate, number of eggs per individual and PA were affected by food quantity. The highest population growth rate was reached by rotifers fed by nutrient-replete food, while it did not significantly differ between rotifers fed on nitrogen (N)-depleted and phosphorus (P)-depleted food. The number of eggs per individual was more affected by N than P supply. The results indicate that B. plicatilis is not able to regulate its digestive apparatus in terms of efficientlygetting access to essential nutrients when scarce, but do this when nutrient-replete food is available in different quantity.
