The returns are particularly interesting with reference to 
flounders. In the first place a very large proportion of these 
marked before the end of the salmon season, September 14th, were 
caught in salmon or trout nets, and usually within a few days 
after being liberated. Secondly, it will be seen that five males* 
migrated northwards to the coast of Fife — three to St. Andrews 
Bay, and two to the north side of the Forth. All the fish were 
mature, and were caught about the same time, February and 
March. We possess only one other record of a distinct migration 
in the case of the flounder. This one was also a male, liberated 
in August, 1905, and recaptured in a trout net off Filey Brigg in 
June, 1906 (see Table VI.) 
The remarkably few returns for dabs do not add materially to 
the facts obtained and recorded before. 
* Since the above was printed several other flounders have been returned from Scottish 
waters, including a mature female from St. Andrews.
