Particles (10) for controlling, treating, feeding of aquatic invertebrate filter feeding organisms such as mussels, clams, oysters and insect larvae comprising a biologically active ingredient (13) embedded within or surround ed by an innocuous carrier material (12). The organism effectively concentrates the active ingredient within its body by feeding on the particles, thereby reducing the total amount of active ingredient required to be used. |
