10.5.6.Crumbles

Cooled pellets may be ground on corrugated rolls and the resulting product sifted into various sizes of granules or crumbles. For small fish, the physical properties of crumbles are often more desired than a meal ration and easier to manufacture than a small pellet. Crumbles provide a multi-faceted surface to reflect light, this being a lure for sight feeders. They ensure that all the ingredients of a formula will be ingested, whereas components of meal feeds separate on entering water, allowing selection of certain ingredients, and the-solution or colloidal suspension of others.
