Incubation tube used to house ovigerous female Uca in a temperature-controlled seawater latter criterion was necessary because females occasionally, though rarely (5 out of 3,015 females), ate their eggs before they hatched. Larval development rates To test the assumption that larval development rates depend on temperature, U. pugilator larvae were reared at 22 and 28°C. About 1 h after hatching, zoeae obtained from females in the incubation tubes were mixed in a glass bowl, concen- trated in a light beam, and transferred by pipette into filtered sea water ( ^m- 34%o salinity) in the compartments of plastic boxes fitted with hinged lids. Ten zoeae were placed into 100 ml of water in each compartment. Zoeae were transferred daily to fresh seawater in clean compartments and fed a surfeit of 1- to 3-h old Artemia salina nauplii. All zoeae were reared under a 14L:10D cycle in an envi- ronmental chamber. The 22°C experiment was begun on the night of 11 May 1979 with 230 zoeae from 9 females. The 28°C experiment was begun on 2 September 1978 with 160 zoeae from 12 females. Zoeae from several females were pooled so that estimates of development rates would include components of variation due to differences among broods. The water temperatures at high tide in the marsh matched the rearing temperatures on the dates the experiments were begun. Plankton samples To determine when megalopae reach the upper estuary, plankton samples were collected during day and night flood tides at a single station near the head of a small.
