Ghoti papers Ghoti aims to serve as a forum for stimulating and pertinent ideas. Ghoti publishes succinct commentary and opinion that addresses important areas in fish and fisheries science. Ghoti contributions will be innovative and have a perspective that may lead to fresh and productive insight of concepts, issues and research agendas. All Ghoti contributions will be selected by the editors and peer reviewed. Etymology of Ghoti George Bernard Shaw (1856-1950), polymath, playwright, Nobel prize winner, and the most prolific letter writer in history, was an advocate of English spelling reform. He was reportedly fond of pointing out its absurdities by proving that ‘fish’ could be spelt ‘ghoti’. That is: ‘gh’ as in ‘rough’, ‘o’ as in ‘women’ and ‘ti’ as in palatial.

Suggestions that anadromy predominates in northern high latitudes because boreal marine seas have high primary productivity are questioned. Instead, post-Pleistocene invasion of far northern fresh waters, which became inhabitable as Pleistocene temperatures ameliorated, via coastal seas, is suggested as a primary cause for northern distributions of widely anadromous fish families. Also, cold temperature preferences may be implicated in determining the ranges of these families, as well as the inhospitability of far northern fresh waters and the lack of ecosystem space to support the huge populations of boreal anadromous fishes. Moreover, there are significant numbers of tropical anadromous fish species.
