This parasiticides is said to be useful and efficient in control of fungi in fish hatcheries. It is also effective against many external parasites.

No doubt with the continuing application of biotechnology to aquaculture, GM breeds will become a viable option in the future. For instance it may be possible to produce "super-species" that are immune to disease, yield better growth and are resistant to global warming. One of the ways to get around the use of chemicals in aquaculture to control parasites is through the use of biotechnology.

Several approaches are currently being researched currently

1) Genetic modification of a fish species to contain a antimicrobial protein from another species eg: Atlantic salmon engineered to produce rainbow trout lysozyme – a potent microbicide against gram negative species

2) Genetic modification of a fish species to contain a antimicrobial genes from other organisms like insects. eg: catfish made to produce cecropin, an antimicrobial protein from the silk worm

3) DNA vaccination – foreign dna is inserted into a fish and it produces a protective protein in that animal only ie: it doesn’t pass on the alteration to its offspring, making it unlike proper genetic modification. There are currently trials undertaking place in Canada , for vaccinating against furunolisis in salmon.
