Resumo: | The aim of the present work is to compare different methods employed for increasing the stability to water of diets used for feeding fish larvae. The various methods of protection tested are : - the addition of gelatin to the diet, -  the encapsulation by synthetic (nylon) or natural (gelatin, zein) polymers, - the coating by zein. The water stability of the unprotected diet particles is very low : only 3 % of the diets are recovered by filtration after 4 hours in water. The addition of 10 % gelatin impro­ves slightly this stability (13 to 25). While encapsulation with nylon considerably increases the water-standing capacity of diets (56 to 66 %), the best results are obtained with the particles encapsulated using natural polymers (74 to 79 %). Though coating with zein offers lesser stability (35 %) this method is tentatively retained due : to the ease of operation, to the absence of risks- of toxicity or loss of solu­ble elements during fabrication and also,due to the possibility of incorporating attraatant substances.
