This compendium presents information on the life history, diet, and abundance and distribution of 46 of the more abundant juvenile and small resident fish species, and data on three species of seagrasses in Florida Bay, Everglades National Park. Abundance and distribution of fish data were derived from three sampling schemes: (1) an otter trawl in basins (1984-1985, 1994-2001), (2) a surface trawl in basins (1984-1985), and (3) a surface trawl in channels (1984-1985). Results from surface trawling only included pelagic species. Collections made with an otter trawl in basins on a bi-monthly basis were emphasized. Nonparametric statistics were used to test spatial and temporal differences in the abundance of species and seagrasses. Fish species accounts were presented in four sections - Life history, Diet, Abundance and distribution, and Length-frequency distributions. Although Florida Bay is a subtropical estuary, the majority of fish species (76%) had warm-temperate affinities; i.e., only 24% were solely tropical species. The five most abundant species collected, in descending order, by (1) otter trawl in basins were: Eucinostomus gula, Lucania parva, Anchoa mitchilli, Lagodon rhomboides, and Syngnathus scovelli; (2) surface trawl in basins were: Hyporhamphus unifasciatus, Strongylura notata, Chriodorus atherinoides, Anchoa hepsetus, and Atherinomorus stipes; (3) surface trawl in channels were: Hypoatherina harringtonensis, A. stipes, A. mitchelli, H. unifasciatus, and C. atherinoides.

An authoritative guide to the identification, systematics, distribution, and biology of the thirty-eight species of the Order Beloniformes in the western North Atlantic Ocean The final volume in the Fishes of the Western North Atlantic series covers the Beloniformes, a diverse order of fishes containing six families and at least two hundred and thirty extant species found worldwide in marine and freshwater environments. This excellently illustrated, authoritative book describes the thirty-eight species of beloniform fishes—needlefishes, sauries, halfbeaks, and flyingfishes—that live in the western Atlantic Ocean. Compiled from new revisions, original research, and critical reviews of existing information, this tenth book in the series completes a major reference work in taxonomy and ichthyology for both amateurs and professionals, and all students of the sea.

Furthermore, sponges are extremely fragile and easily damaged by contact with fishing gear. High rates of fishery bycatch clearly indicate a strong interaction between existing fisheries and sponge habitat. Bycatch in fisheries and fisheries-independent surveys can be a major source of information on the location of the sponge fauna, but current monitoring programs are greatly hampered by the inability of deck personnel to identify bycatch. This guide contains detailed pecies descriptions for 112 sponges collected in Alaska, principally in the central Aleutian Islands. It addresses bycatch identification challenges by providing fisheries observers and scientists with the information necessary to adequately identify sponge fauna.Using that identification data, areas of high abundance can be mapped and the locations of indicator species of vulnerable marine ecosystems can be determined.

The Age and Growth Program at the Alaska Fisheries Science Center is tasked with providing age data in order to improve the basic understanding of the ecology and fisheries dynamics of Alaskan fish species. The primary focus of the Age and Growth Program is to estimate ages from otoliths and other calcified structures for age-structured modeling of commercially exploited stocks; however, the program has recently expanded its interests to include numerous studies on topics ranging from age estimate validation to the growth and life-history of non-target species. Because so many applications rely upon age data and particularly upon assurances as to their accuracy and precision, the Age and Growth Program has developed this practical guide to document the age determination of key groundfish species from Alaskan waters. The main objective of this manual is to describe techniques specific to the age determination of commercially and ecologically important species studied by the Age and Growth Program. The manual also provides general background information on otolith morphology, dissection, and preparation, as well as descriptions of methods used to measure precision and accuracy of age estimates. This manual is intended not only as a reference for age readers at the AFSC and other laboratories, but also to give insight into the quality of age estimates to scientists who routinely use such data.

The fourth edition presents expanded treatment of subjects where our knowledge of the Everglades and its restoration has greatly improved. This more detailed coverage includes: Computer modeling and its applications to the Everglades environment Quantified role of water flow in shaping the Everglades landscape The origin and evolution of fixed tree islands Sulfur and related mercury as wetland pollutants Up-to-date summary of the now quantified economic benefits of restoration, shown to be far in excess of the cost The Everglades Handbook: Understanding the Ecosystem, Fourth Edition is a scholarly reference packed cover to cover with scientific information about the ecosystem of the Everglades - taking into account how drastically the Everglades has changed. Topically, the book covers disciplines ranging from ecology, geology, climatology, hydrology, anthropology to conservation biology. Written in Tom Lodge’s trademark accessible style, this extensively researched text is essential reading for anybody trying to understand the challenges we face in restoring this unique ecosystem.
