MENHADEN INDUSTRY 



In 1924 there were in operation 16 menhaden factories in Virginia, 

 14 in North Carolina, 3 in New Jersey, 3 in Delaware, 3 in Florida, 

 2 in Texas, 2 in New York, 1 in Connecticut, and 1 in Georgia, making 

 a total of 45 plants, as compared to 52 in 1923. 



There were produced 21,008 tons of dry scrap and meal, valued at 

 $996,866, 24,409 tons of acidulated scrap, valued at $495,684, and 

 3,923,904 gallons of oil, valued at $1,817,626, making a total produc- 

 tion valued at $3,310,176, as compared to $6,410,553 in 1923. The 

 decrease, amounting to 48 per cent, is due largely to a shortage of 

 fish and has placed the menhaden industry in a precarious position 

 economically.
