  Two aspects viz. feeding preference and economic returns are involved in this case. In my region, the fish breeders have started culturing cat fishes,of course, very recently. These fishes are preferred for consumption due to their less bones/spines; hence are more costly and bring more returns. The usual indian major carps are less preferred due to their spine/many bones in the flesh; hence these are cheaper in the market and bring less return. Depending upon the consumers' choice, the fish farmers are tilting the balance beween cat fishes and IMC, though officially it is not allowed.

  Unnecessary great confusion has been created by the successive contributors to this question. Thesis is the contribution of an individual, and not at all of a team.Thesis is always written in "third person". Make minimum use of passive voice because sentences in active voice are more preferred in scientific writings. No where the use of I or we is made in the thesis except in the "Acknowledgement" Chapter where you should write this in "first person singular" (If you do not know these terms, contact an english teache)r.I guided 29 PG scholars who completed their theses under my supervision and guidance. I also happened to be a member of more than 2 doz PG Sholars' committee. I did examined more than 4 doz theses from many Indian Universities. My university had set rules of thesis wrting thaat are strictly observed, as I listed some of them above. Therefore, there was a perfect similarity in thesis writing. However, great variation was observed among the theses of same unversity of other places. Even the two scholars of the same department were found to follow different patterns of thesis writing. For a scientific article, use of I or We is permitted by some journals and authors have to follow the guidelines of the journal. Most journals strictly follow these guidelines and manuscript of many authors are simply rejected due to the violation of general guidelines. In scientific writings, this is not your choice but this is the choice of the journal that will prevail. Thhe journal is not your teaching room where you follow your own rules.The answer is little bitter as truth is bitter.
