Fresh or formulated: A preliminary evaluation of fresh blue mussel (Mytilus galloprovincialis) and formulated experimental feeds with inclusion of fresh blue mussel on the growth performance of hatchery-reared juvenile slipper lobster (Thenus australiensis)

Recent advances and future directions in practical diet formulation and adoption in tropical Palinurid lobster aquaculture

“…This approach was pioneered with J edwardsii 29,30 in an attempt to make a low carbohydrate feed with large amounts of soluble protein from sodium caseinate. The application of this concept appears to have been limited for this species due to the importance of carbohydrate as an energy source and relatively low protein requirement, however, it features in recently published reference diets for the subtropical lobster Sagmariasus verreauxi and tropical slipper lobsters Thenus australiensis with almost 50% of the feed comprised of sodium caseinate 31,32 …”

“…Mixed fresh seafood has been included for palatability, however, it was recently identified that krill meal is more effective in supporting growth and survival of P. ornatus 48 . An alternative approach has been put forward for slipper lobsters and the temperate spiny lobsters Sagmariasus verreauxi 31,32 and J. edwardsii 29,30 that is based on sodium caseinate, presumably for its highly concentrated water‐soluble protein, and bound with transglutaminase to form protein cross‐linkages rather than relying on starch for binding (Table 5). The combination of transglutaminase and sodium caseinate is used extensively in food technology to recombine meat products and alter textural properties of protein‐bound food, 99,100 and its application to lobster feeds allows more space for the high protein requirement.…”

Essentiality of dietary cholesterol and its interactions with phospholipid in juvenile slipper lobster (Thenus australiensis)

“…Indeed, many decapods appear to have at least some ability to convert other sterols to Chol, through a process of dealkylation, though Chol may still be nutritionally superior for some species and particularly during early development 2 . Likewise, dietary phospholipid and Chol interactions may be particularly important in decapods since phospholipids are often also described as essential nutrients 27 , though the experimental evidence for this is not particularly strong in scyllarid lobsters 28 . It has been proposed that dietary phospholipids may provide additional nutritional benefits through Chol ‘sparing’ effects, the extent to which may be dependent on the species, phospholipid type and combination, and the dietary levels examined 3 .…”
