FISHERY BULLETIN OF THE FISH AND WILDLIFE SERVICE 



Table 1. — United Slates fish production in the Gulf of Mexico and eastern Florida in 1945 

 (In thousands of pounds; based on Anderson and Power, 1950) 



shows that several species are taken onlj- at very 

 low salinities, while many species are taken both 

 at low and at high salinities. Information is 

 lacking as to whether the abundance of the latter 



group is dependent on low salinities. It may be 

 that the nutrients carried by the rivers are of 

 much greater importance than the salinities in 

 determining both distribution and abundance.
