Occurrence Of The Brackish Water Asellote Isopod Munna (Uromunna) Reynoldsi In Texas, Betty J. Callahan, Scott T. Clark, Philip B. Robertson

Gulf and Caribbean Research

The asellote isopod Munna (Uromunna) reynoldsi Frankenberg and Menzies, previously known from coastal swamps a t Sapelo Island, Georgia, is reported from Texas. Several specimens were collected in grab samples from Fence Lake, a small brackish marsh lake (salinity 0 to 2.7 ppt) in Sca Rim State Park, and in a nearby coastal marsh (salinity 4.4 ppt). The present records indicate that the species is a brackish water form.

The Effect Of Depth On Survival And Growth Of Oysters In Suspension Culture From A Petroleum Platform Off The Texas Coast, John Ogle, Sammy M. Ray, W.J. Wardle

Gulf and Caribbean Research

The effect of depth on oysters in suspension culture from a petroleum platform off the Texas coast was monitored for 20 months. Growth and condition was similar for adult oysters cultured at five levels down to 8 m. Oysters had a growth rate of 1.2 mm (level 3) to 1.4 mm (level 1) per month,representing an increase in length of 94% to 150% for the 20 months. The condition was best in June 1973 after five months placement offshore (condition index of 14.8, 15.5, 14.7, 13.5 and 13.2 for levels 1 through 5, respectively). The condition was lowest in June …
