. Commercial fisheries review. Fisheries; Fish trade. BLUE CRABS ABOUND IN CHESAPEAKE BAY Blue crabs are more abundant in Chesa- peake Bay now than at any time in the past 90 years. Not since commercial fishing started in the 1870s have so many been reported. This bountiful supply was predicted in Oc- tober 1968by W. A. Van Engel of the Virginia Institute of Marine Science, and Robert L. Lippsonof Maryland's Chesapeake Biological Laboratory. The 2 scientists predicted a Virginia-Maryland catch--b a r r in g trouble from weather, labor, and markets--of over 100 million pounds from September 1969 through August 1970. The previous 12-month high was 97|^ million pounds m 1966. They also predicted the catch could remain high through December 1970. Hatched In 1968 Many of the crabs hatched in 1968 had reached mature size by September 1969; these will support the commercial fishery until early summer 1970. Crabs hatched late in 1968 will reach maturity m early summer 1970, supporting the fishery until the end of the year. Catch Doubled in Fall 1969 This abundance follows almost 2 years of scarcity--1968 andfirst two-thirds of 1969-- when production fell to less than half former levels, and prices rose to record highs. Through November 1969, crab potters already had doubled their fall 1968 catches. The win- ter dredge fishing began on December 1, 1969. Virginia vessels should have been able to take the 25 barrels a day per-boat-catch limits in record time. Hurricane Damage Van Engel warned that the full effect of Hurricane Camille on Virginia stocks may not. Crab dredge boat. yet be known. Torrential rains and high run- off caused substantial reductions in river and bay salinities. This resulted in some fresh- water kill of crabs on the James and York rivers. Since experimental trawl and dredge surveys have not located as many crabs as expected, the kill might have been even great- er than originally thought. Poor 1969 Hatch Van Engel and Lippson are pessimistic about the 19
