The demand for signal crayfish led to interest in developing intensified aquaculture practices as far back as the 1970s. More recently, there has been interest in developing optimal culture conditions for hatching and raising juveniles. There has also been a recent surge in attention to developing compound diets for this species for use in intensive or semi-intensive culture. However, these recent efforts have primarily been based in Sweden, Spain, and other countries where this species has been introduced. To date, little work has been done on this species in its native range. Furthermore, despite a growing body of literature, these studies have primarily examined the effects of diet on growth and survival in juveniles, and there have been few studies looking at the digestibility of feed ingredients in adult signal crayfish. The primary objective of the current study, therefore, was to determine the suitability of duckweed (Lemna minor) as a dietary ingredient in signal crayfish feeds through both growth experiments using juveniles and digestibility studies with adults, and to compare these results with a commonly used fish meal substitute, soybean (Glycine max) meal"--Introd., p. [1]-2. |
