(Gadus merlangus), the cod (Gadus morrhua), and the 

 herring (Clupea harengus). Less commonly the lemon sole 

 (Pleuronectes microcephalus) , the brill (Rhombus Icevis), and 

 the gurnard (Trigla gurnardus) are taken. Various inedible 

 fishes are frequently caught, the commoner of which are 

 Solea lutea, Trachinus, Cottus, Centronotus, Ammodytes, and 

 with every haul a great number of invertebrates are taken. 

 Often the crabs (Portiuius) brought up form half the bulk 

 of the catch. Starfishes (Asterias) are nearly always 

 caught. In the warmer months large medusae are 

 abundant.
