In 1950 the Venus population was evenly distributed throughout very soft mud 

 (wattenschlick) and densely packed sand and pebble. In 19 54 only a few clams 

 survived in the hard packed gravel, and none elsewhere. The decrease in 

 numbers was attributed primarily to gull predation. Another predator was 

 green crab, Caroinides maenas . - J.L.M.

Venus meroenaria spawns successfully only in temperatures of about 6 8 to 70°F 

 but winters successfully where water chills to 34 to 35°F. Potentiality to 

 extend its range northward is limited more by summer than by winter temps, for 

 successful reproduction is necessary if a stock is to be maintained. - J.L.M.

Absence of a commercial fishery for Meroenaria campechiensis in Tampa Bay, Fla. 

 is attributed to undependable annual recruitment, possibly caused by disease 

 and predation. Under favorable conditions, southern quahog sets well and grows 

 rapidly in the estuary. Annual growth of quahogs in Boca Ciega Bay has been 

 studied since 1964. Growth of northern quahog transplanted to Tampa Bay from 

 N.Y. waters also has been measured. Hatchery clams from Oyster Bay, N.Y. grew 

 from about 2.5 mm to over 5 mm in 6 months. Seed clams from Great South Bay, 

 N.Y. grew from 48 mm to about 52 mm in the same period, and to 56 mm in 12 

 months. This was about 1/3 the growth rate of southern quahog in the same 

 area. Marked southern quahogs were set out at 20 stations in Tampa Bay. 

 After 12 months growth in upper Tampa Bay was 9 mm, in the central part of 

 the Bay 11.5 mm, and in the lower Bay more than 12 mm. All plantings were on 

 bottoms free of grass. - J.L.M.

Some effects of hydraulic dredging and coastal development in Boca Ciega Bay, 

 Florida. U.S. Fish Wildl. Serv., Fish. Bull. 67(2): 213-241. 



Filling of 1,400 ha (3,500 acres) by hydraulic dredging has reduced the area 

 of Boca Ciega Bay by about 20% since 1950. It was estimated that the annual 

 standing crop destroyed was 1,133 metric tons (798 kg/ha dry whole weight) of 

 sea grass and 1,812 metric tons of associated infauna. Loss of annual 

 production of biological resources was 25,841 metric tons of sea grass, 73 

 metric tons of fishery products, and 1,091 metric tons of infauna exclusive of 

 meiofauna. This was an annual loss of $1.4 million. Mercenaria oampeohiensis 

 was abundant in lower Boca Ciega Bay, but since these were below the area of 

 greatest alteration, and no damage was mentioned specifically, the hard clam 

 resource presumably was not affected significantly, at least directly, by
