This volume offers a collection of papers on the quantitative assessment of age and growth in Chondrichthyan fishes. It details new hard parts for assessments of age, such as caudal thorns; new techniques like bomb radiocarbon for validation; and reexaminations of previous age and growth models. It also examines the importance of assessing the precision and accuracy of statistical formulas, analyses, and models used in age and growth studies.

Proper designation of Essential Fish Habitat (EFH) is a highly important spatial measure in any management of fishery resources. EFH is defined as those waters and substrates necessary to fish for spawning, breeding, feeding, or growth to maturity, a definition that includes the physical, chemical and biological properties of marine areas and the associated sediment and biological assemblages that sustain fish populations throughout their full life cycle.

This book presents latest advances in EFH mapping and modelling and introduces the environmental approach to EFH identification...

The present work evaluates the toxic effects of some environmental stressors on fish eggs and larvae and describes the biomarker responses of fish from locations with varying levels of pollution. Development of the main groups of biomarkers is discussed. The book demonstrates general trends and specific peculiarities of biomarker induction in early fish life and their association with the animal s developmental stages. It addresses responses of fish eggs and larvae to pollution under experimental conditions and presents information obtained from in situ studies.
