Publisher's Synopsis
Excerpt from Observations on Fishes and Other Biota of East Lagoon, Galveston Island
The importance of estuaries, bays, and lagoons to many marine organisms, especially in their developmental stages, is clearly recognized. To add to the limited knowledge of one such area, biological collections over an extended period were made in the vicinity of the mouth of East Lagoon, a narrow, mile-long body of water located in the northeastern end of Galveston Island (fig. This paper presents the seasonal distribution and abundance of its principal fauna as determined by these collections.
East Lagoon was formed by dredging operations during the construction of Galveston's sea wall in 1917-1919. For a number of years the lagoon's protected waters were used extensively for recreational purposes. However, as the only water exchange between the lagoon and Bolivar Roads was tidal seepage through the rock breakwater (fig. 2) and occasional storm tides, a stagnant condition slowly began to develop, especially at the head of the lagoon. To alleviate this condition, the u.s. Corps of Engineers installed seven concrete culverts in October 1953, connecting the lagoon directly with Bolivar Roads. The resulting tidal currents flowing through the culverts were usually strong enough to stream plankton nets, and periodic collections of biological material were made at this location (fig. Field work began in November 1953 and continued through May 1958, averaging about one collection every 4 days.
