CHERAX DESTRUCTOR (CLARK, 1836) AND CHERAX QUADRICARINATUS (VON MARTENS, 1868): SAFETY AND NUTRITIONAL QUALITY- Premio "YOUNG INVESTIGATOR AWARD"
Two species of freshwater Parastacidae (Cherax quadricarinatus and Cherax destructor) are used for breeding in several country and to date also in Italy in one aquaculture plant located near Catania (Sicily). Although they are Australian, they seem to have some of the peculiar properties that make it important, strategic and highly appreciated species for aquaculture facilities in Italy. In fact, they mature early, have multiple reproductive cycles in a year, females can lay over a thousand eggs in a single brood and seem to tolerate wide ranges of temperature (Haubrock et al., 2021). Several authors have studied the Cherax genus from different points of view: diseases, moulting phases and …
Haemolymphatic Parameters in Two Aquaculture Crustacean Species Cherax destructor (Clark, 1836) and Cherax quadricarinatus (Von Martens, 1868)
In the last few years, there has been a notable development in the breeding of freshwater shrimp (astaciculture), which involved various species and in particular, the two Australian Parastacidae species, Cherax destructor and Cherax quadricarinatus. Information about the haemolymphatic parameters of these two species is fragmentary, and filling these gaps becomes important given their importance in aquaculture. Cellular and biochemical parameters were analyzed in both species to create a reference baseline for these parameters to identify the state of welfare or suffering of these animals. The results showed that the total haemocyte count, haemocyte subpopulations, enzymatic activities and…
Haemolymphatic parameters in two aquaculture crustacean species Cherax destructor (Clark, 1836) and Cherax quadricarinatus (von Martens, 1868)
The growing demand for animal proteins of aquatic origin such as fish, molluscs and crustaceans have prompted some European and Italian companies to focus their attention on some species of freshwater crustaceans such as Cherax destructor and Cherax quadricarinatus. They are among the largest freshwater decapods, matures early, females can lay over a thousand eggs in a single brood and has a broad environmental tolerance. All these characteristics make it highly appreciated species for aquaculture and few years ago their breeding has spread to Europe and recently also in Italy (Sicily). Although some commercial yabby farms have been studied these species from different points of view (dieta…
