ABSTRACT 



The atlas contains profile sections depicting the 

 distribution of some oceanographic properties in 

 Tampa Bay, Fla., and adjacent waters of the Gulf 

 of Mexico for the period October 1958 to August 

 1961. Isopleths are given in vertical section for 

 temperature, salinity, and sea-water densit>' (sigma- 

 t). Inorganic phosphorus (PO.,-P), total phosphor- 

 us (total-P), nitrogen (NO3-N) and (NOj-N), cop- 

 per (Cu), silicon (SiOs-Si), and Gymnodinium 

 breve (the Florida red-tide organism) are also given 

 in vertical section, but numerically rather than as 

 isopleths.

257. Report of the Bureau of Commercial Fish- 

 eries Bioloofical Laboratory St. Petersburg- 

 Beach, Florida Fiscal Year 1966. By James 

 E. Sykes. August 1967, 18 pp., 14 figs., 2 

 tables. 



ABSTRACT 

 This is the third fiscal report of the Bureau of 

 Commercial Fisheries Biological Laboratory, St. 

 Petersburg Beach, Fla. Progress in Estuarine and 

 Red-Tide Research Programs is described by project. 

 The application of biological information toward the 

 maintenance and conservation of estuarine zones is 

 stressed. The programs are designed to document 

 the relatively unknown scope of biological produc- 

 tivity in the coastal zones of the eastern Gulf of 

 Mexico, to measure the effect of changes in these 

 zones, and to develop methods of increasing marine 

 organisms which can be used by man.

259. Steps to effective sanitation in smoked- 

 fish plants. By Jack B. Dougherty and Harry 

 L. Seagran. April 1967. iii + 12 pp., 13 figs. 



ABSTRACT 

 Effective sanitation procedures for use in smoked- 

 fish plants are briefly described. Included are sec- 

 tions pertaining to plant design, construction, and 

 maintenance; water and waste systems; cleaning 

 and sanitizing methods and materials; personal hy- 

 giene; and problem areas to avoid in regard to bac- 

 terial contamination of finished product. 



260. Report of the Bureau of Commercial Fish- 

 eries Biological Laboratory, Gulf Breeze, Flor- 

 ida Fiscal Year 1966. By Philip A. Butler and 

 Robert F. Johnson. June 1967, iii + 15 pp., 

 12 figs., 2 tables. 



ABSTRACT 

 The program of the Laboratory has been con- 

 cerned since 1958 with evaluating the effects of 

 pesticides — primarily synthetic organic chemicals — 

 on marine plants and animals. Projects are de- 



signed to determine existing pollution levels, con- 

 centrations causing acute and chronic effects, and 

 the translocation of residue in the biota and envi- 

 ronment.

262. Report, Technological Laboratory Bureau 

 of Commercial Fisheries Pascagou'a, Missis- 

 sippi for fiscal year ending June 30, 1966. By 

 Travis D. Love and Mary H. Thompson. Sep- 

 tember 1967, iv + 14 pp., 8 figs., 7 tables. 



ABSTRACT 

 Results of research on the composition and nu- 

 tritive value of seafoods, the processing difficulties 

 encountered with shrimp, and methods for the re- 

 moval of pesticide residues from seafoods are de- 

 scribed. Microbiological studies on microorganisms 

 of public health significance and Salmonella in fish- 

 ery products are presented, as are the results of 

 the survey of the Gulf of Mexico for the presence 

 of Clostridium hotulinnm. Other activities of the 

 Laboratory staff are acknowledged as are the staff 

 publications for fiscal year 1966. 



263. Field guide to the flatfishes of the family 



Bothidae in the western North Atlantic. By 



Elmer J. Gutherz. October 1967, iv -|- 47 pp., 



48 figs. 



ABSTRACT 



Keys are presented to facilitate both field and lab- 

 oratory identification of the 14 genera and 47 species 

 in the family Bothidae from the western North .A.t- 

 lantic, particularly those south of Cape Hatteras, 

 N.C. Illustrations for all species (except Bothus 

 ellipticus) , the salient familial and subfamilial char- 

 acteristics, and short descriptions with geographic 

 and bathymetric ranges are given.

 September 1967, iii + 14 pp.. 17 figs. 



ABSTRACT 



Activities of the past year included explorations 

 by the R/V Oregon in the South Atlantic Ocean 

 and Caribbean Sea, collection of data on shrimp be- 

 havior, and work on other research projects.
