Excerpt from Pilchard Eggs and Larvae and Other Fish Larvae, Pacific Coast, 1951 In the tables. Pilchard eggs are enumerated by age (in days) since spawning; pilchard and anchovy larvae by size categories; and for the rs maining Species a tabulation is given of the numbers taken. The haul data for the 1951 collections have already been presented in the report on Zooplankton Volumes off the Pacific Coast, 1951 (special Scientific Report: Fisheries No. 73, May However, a record of the standardized haul factors was not included, and they are presented as Table I in this report.

This comprehensive synthesis of our knowledge of the biostratigraphy of marine plankton is the work of an international team of eighteen authors. It covers all the major fossil groups that can be used to date sediments and rocks in the time interval Late Mesozoic to Holocene. Altogether more than 3200 taxa are considered, almost all of which are illustrated and depicted on range charts, making the book a valuable work of reference in the earth sciences. For ease of reference by specialists interested in either calcareous or non-calcareous microfossils, the original work is now divided into two independent volumes. Volume 2 describes siliceous and other non-calcareous microfossils, covering radiolaria, diatoms, silicoflagellates, dinoflagellates and ichthyoliths.

The term "zooplankton" describes the community of floating, often microscopic, animals that inhabit aquatic environments. Being near the base of the food chain, they serve as food for larger animals, such as fish. The ICES (International Council for the Exploration of the Sea) Zooplankton Methodology Manual provides comprehensive coverage of modern techniques in zooplankton ecology written by a group of international experts. Chapters include sampling, acoustic and optical methods, estimation of feeding, growth, reproduction and metabolism, and up-to-date treatment of population genetics and modeling. This book will be a key reference work for marine scientists throughout the world. - Sampling and experimental design - Collecting zooplankton - Techniques for assessing biomass and abundance - Protozooplankton enumeration and biomass estimation - New optical and acoustic techniques for estimating zooplankton biomass and abundance - Methods for measuring zooplankton feeding, growth, reproduction and metabolism - Population genetic analysis of zooplankton - Modelling zooplankton dynamics This unique and comprehensive reference work will be essential reading for marine and freshwater research scientists and graduates entering the field.

Fjords are deep, glacia11y carved estuaries that are pecu1iar to certain coast1ines, and have severa1 characteristics that dist inguish them from sha110wer embayments. At higher latitudes they indent the western coast1ines of Scandinavia, North and South America, and New Zea1and. They are a1so a common feature of much of the arctic coast1ine. The papers contained in this vo1ume were presented at a workshop funded by the NATO Advanced Studies Institute in Victoria, British Co1umbia. It may seem curious to the reader that this specia1 c1ass of estuaries shou1d have attracted an international gathering of oceanographers from severa1 different discip1ines. The reas on for this interest stems from both practica1 and scientific considerations. On the one hand, fjords are a feature common to the coast1ines of severa1 countries that depend heavi1y on the oceans for communication, fisheries and other resources. The impact of man's activities on these coasts has created a demand for new know1edge of the physica1, bio10gica1 and chemica1 aspects of fjords. Sometimes man's inf1uence on the ocean is intentiona1 as, for examp1e, in the artificia1 contro1 of ice cover; often it is the more insidious bui1d-up of toxic wastes that is of concern. These prob1ems are particu1ar1y acute where the conf1icting demands of fisheries, industria1 deve10pment and re creation meet in a sing1e fjord; and indeed, this is a common occurence a10ng severa1 of the fjords in Scandinavia and Canada.
