Available in PDF, EPUB and Kindle. Book excerpt: Atlantic menhaden, Brevootia tyrannus, the object of a major purse-seine fishery along the U.S. east coast, are landed at plants from northern Florida to central Maine. The National Marine Fisheries Service has sampled these landings since 1955 for length, weight, and age. Together with records of landings at each plant, the samples are used to estimate numbers of fish landed at each age. This report analyzes the sampling design in terms of probability sampling theory. The design is classified as two-stage cluster sampling, the first stage consisting of purse-seine sets randomly selected from the population of all sets landed, and the second state consisting of fish randomly selected from each sample set. Implicit assumptions of this design are discussed with special attention to current sampling procedures. Methods are developed for estimating mean fish weight, numbers of fish landed, and age composition of the catch, with approximate 95% confidence intervals. Based on specific results from three ports (Port Monmouth, N.J., Reedville, Va., and Beaufort, N.C.) for the 1979 fishing season, recommendations are made for improving sampling procedures to comply more exactly with assumptions of the sampling design. These recommendations include adopting more formal methods for randomizing set and fish selection, increasing the number of sets sampled, considering the bias introduced by unequal set sizes, and developing methods to optimize the use of funds and personnel.

Download or read book Fishes of Indiana written by Thomas P. Simon and published by Indiana University Press. This book was released on 2011 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indiana has more fish species than any other state north of the Ohio River. This rich variety of fish fauna is on display in this informative and beautifully illustrated guide. From the large freshwater species like the Paddlefish, Lake Sturgeon, and Mooneye, to Great Lakes species like the whitefish, Lake and Brook trout, and Longnose sucker, this book has them all--plus lesser-known species and a few thought to have disappeared from the state. Each species is represented by a descriptive entry containing diagnostic information, conservation status, habitat preferences, diet, reproductive biology, and other facts to assist in identification; a map showing the geographical distribution of the species across Indiana; and a taxonomically accurate and precise illustration.

Download or read book Methods for Fish Biology written by Carl B. Schreck and published by . This book was released on 1990 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed as both a reference and a handbook for the study of fishes. It is a source of methods commonly used to research fish genetics, systematics, anatomy, physiology, developmental biology, toxicology, behavior, and ecology. Standard methods and their theoretical framework are presented for all these fields. Each of the book's 20 chapters also contains a background literature review which, though not exhaustive, allows readers to delve more deeply into subjects that particularly interest them. The main emphasis is on methodology, but the pros and cons of alternative procedures also are treated, as are the uses and misuses of data generated by the techniques.
