Available in PDF, EPUB and Kindle. Book excerpt: The genus Sebastes consists of over 100 fish species, all of which are viviparous and long-lived. Previous studies have presented schemes on the reproductive biology of a single targeted species of the genus Sebastes, but all appear to possess a similar reproductive biology as evidenced by this and other studies. This atlas stages major events during spermatogenesis, oogenesis, and embryogenesis, including atresia, in six species of Sebastes (S. alutus, S. elongatus, S. helvomaculatus, S. polyspinis, S. proriger, and S. zacentrus). Our study suggests that the male reproductive cycle of Sebastes is characterized by 11 phases of testicular development, with 10 stages of sperm development and 1 stage of spermatozoa atresia. Ovarian development was divided into 12 phases, with 10 stages of oocyte development, 1 stage of embryonic development, and 1 stage of oocyte atresia. Embryonic development up to parturition was divided into 33 stages following the research of Yamada and Kusakari (1991). Reproductive development of all six species examined followed the developmental classifications listed above which may apply to all species of Sebastes regardless of the number of broods produced annually. Multiple brooders vary in that not all ova are fertilized and progress to embryos; a proportion of ova are arrested at the pre-vitellogenic stage. Reproductive stage examples shown in this atlas use S. elongatus for spermatic development, S. proriger for oocyte development, and S. alutus for embryological development, because opportunistic sampling only permitted complete analysis of each respective developmental phase for those species. The results of this study and the proposed reproductive phases complement the recommended scheme submitted by Brown-Peterson et al. (2011), who call for a standardization of terminology for describing reproductive development of fishes.

Available in PDF, EPUB and Kindle. Book excerpt: "A major landmark contribution to fisheries science and fish ecology. Rockfish populations are in a severe decline throughout the Northeastern Pacific, and the need for a deep understanding of their biology, ecology, and management has never been more critical. This book addresses all aspects of our current knowledge of this diverse and interesting group of groundfish species, and it is written clearly and with humor. An outstanding work!"--Larry G. Allen, California State University, Northridge "Quite simply the best account ever of the fascinating, diverse, and valuable rockfishes. If you are interested in the marine fishes of the Pacific Coast, you need this book."--Peter B. Moyle, author of Inland Fishes of California

This book was released on 2018-09-25 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology and Ecology of Venomous Marine Scorpionfishes examines the diversity, utilization, and ways to safeguard against the world’s most dangerous fish species. It covers the biological and ecological factors that differentiate each species in the Scorpaeninae (Scorpionfish) family and its Pteroinae (Lionfish) subfamily. This book offers important anatomical and identification information on marine scorpionfishes and delves into the diversity, habits and behaviors of each venomous species. In addition, it discusses the health risks that can plague these fish in and out of the wild, including parasites. This book is an essential resource to educate marine biology researchers and students on the various species of scorpionfish that also provides sea-goers with a guide that will help protect them against venomous stings from these fish. Details the importance of researching and safeguarding against scorpionfishes Covers venomous scorpionfish species within 25 genera, including various lionfish, rockfish and the blackfoot firefish Details the anatomy of scorpionfishes to prevent human contact with their numerous barbs
