A review of nutritional biology and dietary requirements of redclaw crayfish Cherax quadricarinatus (von Martens 1868)

Effect of attractant stimuli, starvation period and food availability on digestive enzymes in the redclaw crayfish Cherax quadricarinatus (Parastacidae)

“…These behavioral characteristics affect the physical properties of feed pellets, such as water stability (hydrostability), and as a consequence, water quality (Saoud et al 2012). Inasmuch as food is a significant expense in aquaculture production systems, the need to maximize food consumption and reduce wasted food is fundamental for economic success (Lee & Meyers 1996).…”

The effects of adding microbial biomass to grow-out and maturation feeds on the reproductive performance of black tiger shrimp, Penaeus monodon

“…The processes associated with reproductive development and maturation require intense protein biosynthesis, whereby the parent must sustain not only its own metabolic needs, but also fuel the nutritional requirements of the developing embryos (Harrison, 1990;Wouters et al, 2001a). This coupled with the larger body size of broodstock relative to juveniles have solidified the critical importance of adequate dietary protein availability and storage in the reproductive biology of decapod crustaceans (Castille and Lawrence, 1989;García-Guerrero et al, 2003;Harrison, 1990;Rodriguez-Gonzalez et al, 2006;Rodriguez-Gonzalez et al, 2013;Saoud et al, 2012;Wouters et al, 2001a). As such, the reduced protein content of the MB maturation diet overall may still have contributed to the reduced hatch rates; however the sole impact on egg hatching that these Treatment combinations are represented based on diet treatments fed, where: C + C = control grow-out and maturation diet; C + MB = control grow-out diet with MB maturation diet; MB + C = MB grow-out diet with control maturation diet; MB + MB = MB grow-out and maturation diet; Gdiet = grow-out diet; Mdiet = maturation diet; n.s.…”

From fish‐processing waste to feed additives for crayfish

“…In crustaceans, exogenous enzymes have been used as feed additives only for Penaeus vannamei (Córdova‐Murueta et al, ; González‐Zamorano, Navarrete del Toro, & García‐Carreño, ), but little is known about their effect on other decapod species such as Cherax quadricarinatus . Currently, this species is cultured intensively and semi‐intensively in many countries throughout the world (Saoud, Garza De Yta, & Ghanawi, ). Its worldwide production has increased from 150,000 m.t.…”
