Advocates of transgenesis consider it an effective means of improving the productivity of aquatic animals. This method is not only time-consuming procedure for animals such as fish that produce a large number of eggs and labour intensive but is also limited by the physiology of fish eggs. Introduction of transgenic fish into natural communities is a major ecological concern. Growth acceleration in fish has been one of the targets of gene transfer experiments. It is shown that the DNA injected into the cytoplasm of fertilized zebra fish eggs could integrate into the fish genome and be inherited in the germ line. Electroporation method: Electroporation has been shown to be the most effective means of gene transfer in fish since a large number of fertilized eggs can be treated in a short time by this method. Only about one out of every 100 eggs microinjected will stably incorporate the recombinant DNA sequence into its genome and subsequently transmit the transgene to its progeny. Among the major food fish species are carp (Cyprinus sp. Microinjection that allows delivery of the transgene directly into the nucleus, Transgene is directly microinjected into the male pronuclei of fertilized eggs. Transgenic strains provide useful model systems for studying the consequences of growth enhancement from genetic, physiological and ecological standpoints. The first transgenic fish were produced in and as of 2003, more than 35 species had been genetically engineered in research laboratories worldwide. “If, as in our experiments, the genetic change also reduces the offspring’s ability to survive, a transgenic animal could bring a wild population to extinction in 40 generations”. Inducing transgenesis is a relatively transgene. Because of this, the food production of the aquaculture farm using the transgenic fish would increase substantially with fewer costs or start-up time. The Green Fluorescent Protein (GFP) from Jellyfish (Aequorea victoria) has been used for this purpose in zebrafish.

The development of transgenic fish can serve as excellent experimental models for basic scientific investigations, environmental toxicology and in biotechnological applications, writes Dr Subha Ganguly, Arawali Veterinary College, India. WorldFish is a member of CGIAR, a global agriculture research partnership for a food secure future. The most established method for gene transfer in fish is microinjection. A number of fish species are in focus for gene transfer experiments and can be divided into two main groups: animals used in aquaculture and model fish used in basic research. AquAdvantage salmon, a modified Atlantic salmon reach commercial size in one-third of the time required for nontransgenic salmon. Disadvantage: The preparation of retroviral particles including the transgene of interest is a very laborious process, increases costs and requires technology. Opponents see it as a threat to both the environment and human health. The Fish Tank promotes discussions and new ways of thinking about fisheries and aquaculture as a means to reduce poverty and increase food and nutrition security. Transgenic fish have been developed for applications such as the production of human therapeutics, experimental models for biological research, environmental monitoring, ornamental fish and aqua cultural production. The presence of a tough chorion layer around the fish eggs reduces efficiency, removal of the chorion is a tedious procedure and introduces additional stress on newly fertilized eggs. Further research should work with the DNA sequences of fish rather than mammalian origin to increase public acceptance and avoid sequences of bacterial or viral origin. The trait of growth rate has received the greatest attention because of its importance in aquatic animal production systems. The development of transgenic animal models represents a revolutionary advance in the study of a variety of disease processes. Production of transgenic fish. The growth rate of Transgenic fish can be increased by 400% to 600% while simultaneously reducing feed input by up to 25% per unit of output, thereby improving food conversion ratios. Transgenic are organisms into which transgene has been artificially introduced and the transgene stably integrated into their genomes. The transgenic fish are also more active and aggressive when feeding, and more willing to risk exposure to predation. The use of the microinjection method results in higher survival rates for manipulated fish embryos than the electroporation method. Microinjection method:Microinjection method has been used successfully in the production of transgenic fish and is a commonly used technique due to its simplicity and reliability. Growth enhanced transgenic fish have improved feed-conversion efficiency, resulting in economic and potential environmental benefits such as reduced feed waste and effluent from fish farms. Our goal is to reduce poverty and hunger by improving fisheries and aquaculture. Learn how your organization can partner with WorldFish.
