1. A liquid crustacean foodstuff comprising:
- an enrobed particulate crustacean foodstuff in a liquid media, the liquid media comprising an antimicrobial,the enrobed particulate crustacean foodstuff comprising a particulate nutrient feed, an inner coating comprising an edible unsaturated oil having a melting point of below about 29°
C. and an outer coating comprising a gel which is complexed or crosslinked to an extent which is effective to contain the oil-coated feed in an aqueous environment and which is ingestible by the crustacean.

14. A liquid crustacean foodstuff comprising:
-
an enrobed particulate crustacean foodstuff in an aqueous liquid medium, the enrobed particulate foodstuff comprising a particulate feed having a particle size in the range of from about 2 to about 100 microns, from about 15 to about 30 weight percent, based upon the weight of the particulate feed, edible unsaturated oil and from about 0.1 to about 5.0 weight percent, based upon the weight of the particulate feed, endo-probiotic bacteria, the liquid media comprising water, an antimicrobial water soluble salt and a liquid antimicrobial selected from the group consisting of propylene glycol, glycerol, propionic acid and mixtures thereof, and an ecto-probiotic bacteria, the enrobed particulate crustacean foodstuff having an inner coating and outer coating, the edible unsaturated oil forming the inner coating on and into the surface of the particulate feed, the oil having a melting point of below about 29°
C. and an iodine value of at least about 85, the outer coating comprising a blend of alginate and gelatin which has been gelled and crosslinked. - View Dependent Claims (15)

16. A method for making a liquid foodstuff for crustaceans and fish, the method comprising:
-
enrobing a particulate feed and a endo-probiotic bacteria with an edible unsaturated oil having a melting point of above about 29°
C. and an iodine value of at least about 85 to provide an oil-coated nutrient feed;embedding the oil-coated nutrient feed in an alginate and gelatin gel; crosslinking the gel to provide an microencapsulated oil-coated feed; sieve separating the microcapsules containing the oil-coated feed to provide microcapsules with a diameter of from about 50 to about 1000 microns; and blending the microcapsules into an aqueous liquid media comprising water, an antimicrobial water soluble salt and a liquid antimicrobial selected from the group consisting of propylene glycol, glycerol propionic acid and mixtures thereof, and a ecto-probiotic bacteria.
