Оценка пищевой ценности детрита осуществлялась посредством анализа показателей роста и репродуктивной активности гидробионтов. Полученные данные указывают на зависимость энергетической ценности детрита от его возраста.</p></abstract><trans-abstract xml:lang="en"><p>Freshwater cladocerans were shown to be able to survive and reproduce for long periods of time, feeding on detritus of various origins. The nutritional value of detritus was determined based on the growth and reproduction rates of the aquatic organisms.
