Book excerpt: Excerpt from Fur Seal Investigations, 1968 Now, 13 years after we first began to reduce the seal population with the expectation that a smaller population would yield larger kills and more stability, we are ready to let it increase in size. The high population of the 1950's has been reduced and held at nearly the same level since 1963. An estimate of the mean kill of males from the year classes at this lower population level and the size of fluctuations to be expected in the kill will be determined from collections of data completed by 1972. The next step will be to find the productivity of the population when it reaches anew, higher level. Information about marked seals continues to upset any of our previous notions about the purity of separate populations in the North Pacific. A small colony of seals that produced young in 1968 on San Miguel Island, off the coast of California, included marked animals from the Pribilof and Commander Islands. A male seal marked in late June 1968 on the Pribilof Islands was taken on the Commander Islands within a month.

Book excerpt: Excerpt from Fur Seal Investigations: Pribilof Islands, Alaska, 1965 Estimates of the number of pups born based on the tag-and-recovery method have long been known to be inflated, mainly as a result of tag-induced mortality and loss of tags. Additional pups are now marked each year by shearing a patch of fur, and estimates of the number born are obtained by sampling for a marked-to-unmarked ratio 1 to 3 weeks later. The estimates from shearing were similar to complete counts of pups on several small rookeries. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2016-12-23 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Pelagic Fur Seal Investigations, Alaska, 1963 Seals were seen in groups rather than in large herds. In 1963, groups of one, two, and three seals accounted for percent of the total sightings. Of seals collected in 1963, 111 were males and were females. Five-year-olds predominated among females. The relative distribution of males and females, with only three exceptions, was fairly uniform. Post partum females predominated in the early July collections in sectors 1 and 2, zones 3 and 4, and in the feeding areas of the outer zones from mid-july to early Sep tember. The first adult males found away from the Pribilof Islands were seen 5-20 miles north west of Akun Island on 31 July. In August they were found widely scattered at sea. More males were collected in Alaska waters than in the waters off California, Oregon, and Washington. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
