Abstract
Over the last decade, fish supplies for human consumption have reached over 100 million tons. Due to overfishing, future increases in demand can only be met from the aquaculture industry. This will require increased research in areas such as the control and manipulation of fish reproduction. There is increasing interest in the oral delivery of peptides that control gamete reproduction. However, compared to mammalian species, little is known about the barriers to peptide delivery and methods to improve such delivery. The three major barriers to peptide delivery are the enzymatic barriers sourced from the host luminal and membrane bound peptidases, the immunological cells present within both the enterocytes and underlying connective tissue and the physical barrier of the epithelial cells. Furthermore, the anatomy and physiology of the gastrointestinal tract of these species are markedly different when compared to higher vertebrates and therefore must be considered when designing appropriate delivery systems. Research to date has focused on the oral delivery and subsequent pharmacodynamic responses to the peptides associated with growth and reproduction. However, minimal work has been undertaken to overcome the identified barriers and therefore any future investigations need to attend to these obstacles before the oral delivery of bioactive peptides can become a commercial reality.
