Book Synopsis Spawning Areas of British Columbia Herring by : D. E. Hay
Download or read book Spawning Areas of British Columbia Herring written by D. E. Hay and published by . This book was released on 1989 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of the geographical distribution of herring spawning in B.C. from 1937-86. The analysis was based on 20,000 records of spawning made annually for different regions of the B.C. coast. For each of 90 geographical subdivisions of the coast, tables are given to show the annual frequency of spawns in 1 km segments of the coast, with the intensity of spawning in specific areas shown by histograms. Separate tables present a statistical summary of spawn records, including mean spawning dates. Tables summarizing roe fishery activity from 1972-86 are shown for each location and a descriptive summary including a classification of the ecological importance of herring spawning habitat is presented for each area.

This book was released on 1988 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herring abundance in the Central Coast district of British Columbia has recently shown signs of decline. A first attempt to survey spawn in the District (with divers) was made in 1986 to accurately assess the status of the spawning stocks. Herring spawns were surveyed independently with traditional surface survey techniques and by scuba divers. Visual observations were made from a boat and grapples were used to determine the presence of and obtain samples of spawn. From these observations the length and width of spawn and the layers of eggs were estimated. Divers took samples of vegetation with eggs attached, they were weighed, and egg counts were obtained. Eggs on the bottom substrate were calculated from diver estimates of the number of egg layers and percent of the bottom covered by vegetation and then added to eggs on the vegetation.
