Polymethylolcarbamide as binder of prawn diets

Abstract

The binding effect of polymethylolcarbamide (PMC) at the levels 0.5% and 1.0% of a practical diet was compared to that of the other binders such as kappa-carrageenan, sodium alginate, carboxymethylcellulose, cornstarch and agar. PMC was found more effective at 0.5% and 1.0% levels as a binder for the formulated practical diet than the other binders used. However, PMC was found ineffective at the same levels, even at 2%, when employed in the semi-purified diet.
