Book excerpt: A study of the pink shrimp, Penaeus duorarum, on the Tortugas fishing grounds was undertaken during 1957 and 1958 to provide information on the nature of the relation between the size of shrimp and the depth of water where they occur, together with fleet concentrations and degree of discarding of small pink shrimp. The average carapace length of both male and female shrimp increased both with depth of water and with northerly distance from the Florida Keys. Small pink shrimp were most abundant from September 1957 through May 1958, appearing on the eastern and southeastern portion of the grounds, where the highest try net catches were made. The fleet concentrated there during December to June but was more widely distributed during the summer. Apparently, few small pink shrimp were discarded.

Book excerpt: Excerpt from Size Distribution of Pink Shrimp, Penaeus Duorarum, and Fleet Concentrations on the Tortugas Fishing Grounds The principal purpose of this study was to investigate the relation between the size of shrimp and the depth of water where they occur. Fishermen's observa tions and research data suggested that pink shrimp on the Tortugas grounds in crease ih size as water depth increases, but details of this relationship were lack ing. A second purpose was to investigate the extent to which fishermen discard small shrimp. A wide range of sizes of shrimp are caught in the trawl nets. The smallest sizes are often thrown overboard with the unusable part of the catch, and the extent to which discarding is done is of importance to an understanding of the fishery. A third purpose was to study the distribution of fishing vessels on the grounds to determine whether effort was concentrated in certain areas, and whether seasons, weather. Occurrence of seaweed and jellyfish, or other factors influence the distribution of fishing. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The micro method of hematocrit is rapidly replacing red cell counts in clinical hematology. Observations were made on the value of this method in routine hematological examination of trouts. Under the conditions of data collection, the normal hematocrit values for brook trout were 45 to 50, for brown trout 39 to 44, and for rainbow trout 45 to 53. There was a close correlation between the hematocrits, red cell counts and hemoglobin. The commercial heparinized capillaries, while excellent for human blood, tend to give somewhat higher readings (7 to 18 percent) with trout, due to incomplete prevention of blood coagulation. The procedure as applied to trout is described in detail.
