The method of stimulating an aquatic life form is disclosed. The method has the steps of activating a pressure pulse or an acoustic shock wave generator or source to emit pressure pulse or acoustic shock waves; and subjecting the aquatic life form to the pressure pulse or acoustic shock waves stimulating said aquatic life form wherein the aquatic life form is positioned within a path of the emitted shock waves. The aquatic life form is a tissue having cells. The tissue can be an egg, zygotic embryo or larvae or an immature or a mature specimen. The aquatic life form may be a fish, shellfish, any crustacean, mussel, slam, oyster, abalone, scallop, shrimp, lobster, crab, crawfish, eel, octopus or any other aquatic life form. The method of stimulating includes activating the cells within the treated tissue thereby releasing growth factor proteins or other chemical compositions promoting growth and accelerating maturization. The tissue may be infected or exposed to infections from microbial sources such as microorganisms or viruses and the exposure to shock waves stimulates an activation of defenses of the immune system.
