  • My studies on Escherichia coli ( coli) has shown that the clustered regularly interspaced short palindromic repeats interference/activation is capable of providing a simple and efficient approach in targeting repression or activation of gene expression in the fish genome. This technique is highly flexible and programmable, using an RNA-guided nuclease-deficient Cas9 (dCas9) of E. coli protein fused with transcriptional regulators for targeting specific genes to effect their regulation. In this approach a single guide RNA (sgRNA) directs E. coli nucleolytically deactivated Cas9 (dCas9) with mutations to a specific locus in the fish genome. This was achieved according to the rules of Watson-Crick base-pairing, thus the 20-bp guide sequence at the 5? end (phosphodiester end) of the sgRNA that specifies the target sequence. On the target fish genomic DNA, the adjacent 5?-NGG Protospacer adjacent motif structure after the 20-bp target sequence was required to efficiently direct the dCas9–sgRNA complex to the fish genomic DNA. Although still on the preliminaries, I expect Turkana Laboratory to be a centre of excellence in understanding changes in wild and cultured fish that makes them resistance to adverse conditions and stresses brought about by frequent environmental and micro-climate changes in the wild and culture based fish farms. This study will provide answers to the limited knowledge on mass fish production both in the wild and cultured fish farms given its simplicity and cost effective in producing required complexes to achieve targeted disease free and high yielding fish.
  • This technology will be combined with fishing gear technology (fishing gear), fish conservation and fish stock assessment to provide a one-stop market for fish production equivalent to non-in the world of fish production and marketing. This technology is expected to alleviate hunger and poverty in developing nations whose annual gross domestic product is still less than 1 trillion dollars, such as Kenya, while answering the government of Kenya’s agenda on food security, vision 2030 and global sustainable development goals number two on food security and hunger.
