The distribution of the wood boring isopod Limnoria in Texas estuaries and bays in relation to environmental factors

Typescript (photocopy). The gribble Limnoria tripunctata and other members of the family Limnoriidae annually cause millions of dollars of damage to wooden structures in the marine environment. Thus it is of considerable economic importance to understand the factors which control the distribution of...

The gribble Limnoria tripunctata and other members of the family Limnoriidae annually cause millions of dollars of damage to wooden structures in the marine environment. Thus it is of considerable economic importance to understand the factors which control the distribution of gribbles. The objectives of this study were: (1)to determine the geographic distribution of gribbles in Texas bays, (2)to determine tolerances of L. tripunctata to temperature and salinity in the laboratory, and (3)to correlate field distribution, laboratory tolerances, and hydrographic conditions in the study area. Wood samples were collected from pilings at 33 stations located in Galveston, Matagorda, San Antonio, Aransas, Corpus Christi, and Baffin Bay systems and the Laguna Madre. Limnoria tripunctata, the only gribble species collected, was present in samples from Bolivar ferry landing, Texas City Dike, West Bay, Christmas Bay, Freeport, Port O'Connor, Port Aransas, Corpus Christi, Kennedy Causeway, Port Mansfield, Port Isabel, and Brownsville. This species has previously been reported from Galveston, Freeport, Port Aransas, Corpus Christi, and Port Isabel. Salinity and water circulation appeared to be the most important factors governing the local distribution of gribbles. Mean salinity (from Texas Parks and Wildlife Department Coastal Fisheries Projects Reports, 1963-1975) was greater than 19('o)/oo at positive stations and less than 22('o)/oo at negative stations. Most positive stations are near passes and are affected by tidal exchange between the Gulf of Mexico and the bay system. .
