1. Grouping of the species according to depth^ 



a. Species spawning only or chiefly within the 200-nieter line (i.e. on 

 the coastal banks) 



Bib (Gadua luscus) and Lesser Forkbeard (Baniceps raninus) as also 

 Whiting {Gadus merlangiis) ; Cod {Gad. callarias) 

 Poor cod {Gad. minutus) ; Pollack {Gad. poUachius) 

 Haddock {Gad. œglefinus) ; Norway pout {Gad. Esmarki) 

 Ling {Molva molva); Coalfish {Gad. virens). 



b. Species sp[awning chiefly about the 200-meter line (i.e. in the neigh- 

 bourhood of the upper slope of the coast'al banks towards the deep 

 water) 



Hake {Merluccius vulgaris); Torsk {Brosmius brosme) 



c. Species spawning about the 1000-meter line (i.e. beyond or on the 

 lower slope of the coastal banks towards the deep water) 



Silvery pout {Gadiculus argetiteus); Poutassou {Gadus Foutassou) 

 Blue ling {Molva byrkelange); Mediterranean ling {Molva elongata) 



2. Grouping of the species according to temperature 

 The following summary is chiefly based on the conditions found during our invest- 

 igations in the Atlantic, but regard is also taken of the conditions in the North Sea, 

 Skager Kak and the Kattegat, as also the Norwegian Sea so far as the conditions in the 

 latter are known to me. 



' The species in this list are arranged as far as possible in successive order according to the depths 

 at which spawning occurs, beginning with those spawning in shallowest water. 



'■^ This species may probably spawn however at a somewhat lower temperature than 8°.
