Recorded here are the outputs from a career as fisheries scientist.
It became evident while working for FAO on developing country problems, that much of my work before 1990 was unavailable to developing country fishery workers, without them having access to a library with fishery and marine science journals. That is to say, my early publications, dating from before pdf’s of papers became available, are hard to find on the web. In bringing my half century of involvement with fisheries matters to a close, I have had time to document my past for those who still see relevance in my work.
Providing pdf’s on a site on Google Cloud is an adventure I hope not to regret!
Until 1999, I was a fisheries expert employed by the UN Food and Agriculture Organization. My experience in fisheries biology, population dynamics and fish stock assessment is reported in some 100+ primary publications and books on fishery-related issues, many of which are given below in electronic form. While at the FAO I was involved in international policy issues, designed national fishery research programs, and drafted government fishery management plans and cooperative projects. FAO reports mentioned below are available through the Organization (see list below).
Although I am long retired from a paid job, this exercise in retrospection gives me time to reflect on my past career as a fisheries scientist. My latest work, a review of the history of scallop research in Canada, put me in the unusual frame of mind to look backwards in time. Autobiographies are unconventional for scientists, and this is only the professional side of my life, and written mainly for my own satisfaction.
Making sense of my career productivity, the following sections divide my research output into categories, expecting that not all categories will be of interest to the average reader. The sequence of publications has been reversed, assuming that interest in the recent papers will be greater than the earlier ones.

A short retrospective on personal research carried out in Eastern Canada in the period 1966-'75 relevant to impacts of fishing gear on the Benthic environment, and some perspectives for further research.
John F. CADDY, Ecoclad Associates (www.ecoclad.com). Impact of trawl fishing on benthic communities - Proceedings: 109-128, 19 November 1999 ©2000 ICRAM.
A summary of underwater and fishing gear research conducted by the author in the 1960's and 1970's provides the context for some suggested directions for future research on the impacts of fishing gear on the benthos, gear selectivity, and field experimentation on the indirect impacts of fishing on the environment.
