While stock-taking the life-time achievements of Professor Hiralal Chaudhuri in the domain of research, teaching and training one has to go through the editor's, Write up detailed in "Preface" and "Introduction".

Three manuals viz., Aquaculture, Limnology and Ichthyology form an intergal and interrelated chain of activities and may be taken as a single unit. In fact the success of the Professor in various facets of Aquaculture promoted Central Government to get hundreds of budding aquaculturists of all ranks to be trained under him, and the manuals aided in his lectures. In fact, the Professor?s various national and international assignments and responsibilities with FAO/UNDP, ESCAP, SEAFDEC, NACA/IDRC and others involved him in coordinated research, training and teaching activities.

Hundreds of officers were trained and even the high-valued Ph.D. and M.S. degree researchers had to be guided by him in their researches. Besides, his experience in teaching since 1943 promoted him to draw outlines for presentation of various multiple details of subjects to the students through lecture notes, transparencies for over-head projector, colour slides and herbarium sheets. The three manuals provide all such data and information. His command over the languages of English, French, German and Latin helped him to explain various scientific terms and significance to the students very lucidly and convincingly. The students, undergraduate and post-graduate, assessed the quality of his teaching as the best among all the groups of lecturers in evaluating their performances which was a system in the University of the Philippines at Los Banos. As such, the manuals have immense value.

In preparation of this treatise on manuals, the editor had to collect various facts from innumerable stray papers as the Professor did not intend to publish them in a book form. Even then it is hoped that the school and College students, researchers, trainers, environmentalists and wildlife managers will find the contents of the manuals very useful in their research investigations as they provide all basic information of Chemistry, Botany, Zoology and Physics involved in the study.
