A method for coloring live bait worms comprises adding to a cultivation bed containing one or more worm storage media, a non-toxic amount of a colorant to form a coloring medium, and incubating live bait worms in the coloring medium at a temperature and for a time sufficient to allow the bait worms to become colored by ingesting the coloring medium. The colorant is preferably a D&C coloring additive such as a xanthene dye, most preferably D&C Yellow No. 8, and/or D&C Yellow No. 7, and the worm storage medium is preferably peat loam. The worms become colored during an incubation period of up to about one week and retain their color for a prolonged period of time after being removed from the coloring medium.
A food composition for feeding to worms to enhance their desirability to predators and process therefor is disclosed. The composition contains a xanthene dye which is applied to the surface of or admixed with a nutritionally acceptable carrier in an amount sufficient to enhance the worm's detection by the visual color receptors of a fish.
The present invention provides a method for the aquaculture of marine deposit feeders, such as Arenicola marina and Arenicola defodiens. The method comprises providing a foodstuff such as brewery yeast or waste from fish farms within the substrate housing the worms. The foodstuff is conveniently particulate or microparticulate to aid intimate admixture with a substrate, which is typically sand.
