niay be carried on if it is done accox'ding to a 

 plan based on fishable capacities and regulated 

 by the quantity of the resources to be used or 

 to be conserved. This procédure, sanctioned 

 by appropriate législation dépends upon biolo- 

 gical studies. 



Food requirements, spawning migrations, 

 the protection of species against disease or 

 parasites, together with environmental condi- 

 tions, are important factors whose values must 

 ail be checked for an understanding of how 

 they conilititioii the behaviour of fish. A 

 greater knowledge of their living conditions 

 détermines the measures to be taken in ensurin^ 

 the natural reconstitution of depleted stock and 

 the prévention of future damage. 



The stress which life imposes upon us today 

 requires compensation through periods of 

 récréation. The sport of fishing pursued in 

 the enchanting environments to be found in 

 our province, oflFers this happy diversion. At 

 the same time, it enables the citizen to come 

 in contact with the Xature from which he has 

 been removed. When we consider the popula- 

 rity of Speckled Trout in Québec and elsewhere, 

 we understand the reason for the efforts made 

 by governmental authorities to préserve this 

 inestimable wealth. 



The modem laboratories of the Biological 

 Centre are furnished with ail the facilities for 

 research necessary to a scientific institution. 

 The location is perfectly adapted to the kind 

 of work carried on. There are modem research 

 instruments and suitable kinds of apparatus. 

 There is ready access to the tanks of the 

 adjoining Aquarium, rendering e.xperimentation 

 on the living species under controlled conditions 

 possible. The amphithéâtre which is accessible 

 to the public for educational purposes is also 

 used by biologists of the Centre and of the 

 exterior for scientific meetings. 



The Biological Centre i.< equipped with a 

 library where the personnel has at hand ail the 

 scientific documentation required in their 

 research, containing thousands of volumes on 

 gênerai biology. ichthyology, fisheries, etc., and 

 hundreds of scientific reviews and bulletins, it 

 provides the means whereby the scientists can 

 keep up to date with work carried on through- 

 out the world. This permanent contact is 

 facilitated by the e.\change of publications is- 

 sued by scientific societies connected with 

 universities and governments, and the contri- 



butions made by the Department of Fisheries 

 of oui province. Among the latter, noted for 

 its interest and its educational value, is the 

 séries on "Poissons de Québec" (Fishes of 

 Québec). The albums are bilingual and 

 magnificently illustrated in colour. They are 

 displayed among the popular books. While 

 they maintain a scientific précision intelligible 

 to the iayman. they make no concession to 

 vague approximation or fantasy which are bo 

 often misleading or \vrongly interpreted by the 

 public. Six albums hâve already been published. 

 This work, which is continuing, contributes to 

 a better understanding of the conservation of 

 our fauna. 



Among the facilities of the Biological 

 Centre, we must not overlook the studio. Hère 

 an artist permanently attached to the laboratory 

 is responsible for illustrating the publications, 

 making colour reproductions according to the 

 nature of the fish, drawings of fishing gear.
