11. Brill (Rhombus laevis Rond.). This agrees with the turbot in respect to its 

 habitat. The average catch per day was: 



1902 1903 



077 pounds 0'62 pounds. 



The very small quantities do not permit further conclusions. 



12. Plaice (Pleuronectes platessa L.). The following were the average catches per day : 



1902 1903 



I-II sort V65 pounds 20'33 pounds 



HI „ 19-86 „ 9-01 „ 



27-51 pounds 29-34 pounds. 



A strong maximum occurred in August and September 1902, and the same maximum 

 is found in August 1903, (there was no fishing in September 1903). In both years, a 

 minimum occurred in the cold months. 



13. Pleuronectes cynoglossus L. and PI. microcephalus Donov. or witch 

 and lemon dab, are taken together. Both are northern forms, cynoglossus prefers in 

 general, the greater depths, microcephalus the intermediate. 



The proportions of these two species, in the quantities landed under the common 

 name from the various fishing places, cannot be made out from the existing statistics for 

 1902 and 1903. To clear up this point, our work must be continued. 



The average catch per day of both together was: 



1902 1903 



80-97 pounds 70-74 pounds. 



A distinct maximum lies in the winter months (about October to April), and a distinct 

 minimum in the summer months (only about 8 pounds as the average per day in August 

 of both years). 



14. Dab (Pleuronectes limanda L.). This forms but a small part of the total catch. 

 The average catch per day of fishing was: 



1902 1903 



6-35 pounds 1 1 -39 pounds. 



The catch was largest in the winter months of both years (October — February). 



15. Halibut (Hippoglossus vulgaris Fl.) has only amounted to about 3 pounds 

 per day on an average, for both years. As the fish has a great weight, this means but 

 isolated catches, from which no general conclusions can be drawn. 



16. Rays. Their average per day amounted to: 



1902 1903 



21-01 pounds 26-29 pounds. 



Most are taken in the months of November— December, the least in July— August. 

 The first months of the year have about the average.
