Microencapsulation of hydrosoluble additives to artificial diets for cyprinid larvae to avoid leaching

The effects of microencapsulated garlic (Allium sativum) extract on growth performance, body composition, immune response and antioxidant status of rainbow trout (Oncorhynchus mykiss) juveniles

“…The use of encapsulation in order to incorporate additives in commercial diet of fish is an important strategy for aquaculture industry (Vanegas-Espinoza et al 2019). Cyprinid larvae fed diet supplemented with hydrosoluble vitamins and minerals had poor growth and survival, due to leaching of the additives (Petitjean and Csengeri 1995). These must be protected and microencapsulation seems a good method for protection.…”

Chitosan as a wall material for a microencapsulated delivery system for Macrobrachium rosenbergii (de Man) larvae

“…Microencapsulated drug delivery in aquaculture has so far been accomplished with biopolymers of different origin such as natural gums (Kanazawa 1981), proteins (Petitjean & Csengeri 1995;Yufera, Kolkovski, Fernandez-Diaz, Rinchard, Lee & Dabrowski 2003) and lipids (Lopez-Alvardo, Langdon,Teshima & Kanazawa 1994;Onal & Langdon 2004). However, chitosan has not been evaluated as a wall material so far, despite its favourable characteristics like gelation on contact with counter anions (Bodmeier, Oh & Pramar 1989), formation of ¢lms soluble in acidic pH (Remunan-Lopez & Bodmeier 1996) and its susceptibility to digestive enzymes (Remunan-Lopez, Lorenzo-Lamosa, Vila-Jato & Alonso 1998).…”
