THE REACTION OF PROTEINASES ON FRESH AND PROCESSED ANIMAL AND VEGETABLE PROTEIN SUBSTRATES TO PRODUCE HYDROLYSATES THAT ELICIT A STRONG SUSTAINED FEEDING RESPONSE IN MARINE FISHES, AND TO USE THESE HYDROLYSATES TO INCREASE THE METABOLIC RATE OF AQUATIC ORGANISMS

摘要

A process for manufacturing a berley composition is disclosed. The process includes mofifying proteins and/or polypeptides by reacting a modifying agent with the proteins and/or polypeptides to form said berley composition comprising a protein modified mixture. A berley composition comprising a protein modified mixture is also disclosed. Also disclosed are a process of preparing a berley/bait for marine vertebrates and/or marine invertebrates, a method of attracting marine vertebrates and/or marine invertebrates, a method of increasing the weight of marine vertebrates and/or marine invertebrates, a method of increasing the metabolic rate of marine vertebrates and/or marine invertebrates, a method of increasing the growth rate of marine vertebrates and/or marine invertebrates, a method of increasing the feeding response of marine vertebrates and/or marine invertebrates, a method of increasing the sexual behaviour of marine vertebrates and/or marine invertebrates, a method of increasing the aggressive behaviour of marine vertebrates and/or marine invertebrates and a method of increasing the stress response behaviour of marine vertebrates and/or marine invertebrates.
