Tilapia and other species of fish can be raised in earthen ponds, cement raceways and tanks, cages and enclosures. This focus on construction of ponds, tanks, raceways and cages. It covers the how, what, where and why of every type of water system needed for fish farming. The book explores the latest for building, use of equipment as well as terrain conditions, plus current technologies.
This is the first taxonomic guide of deep sea organisms for the Channel Islands National Marine Sanctuary. From April 21 to 27, 2011, the NOAA ship Okeanos Explorer started their field season with a shakedown cruise primarily to field test equipment. The cruise also provided an opportunity to conduct multibeam mapping and a series of exploratory dives using the Little Hercules Remotely Operated Vehicle (ROV) in Channel Islands National Marine Sanctuary. The ROV explored areas that had not been surveyed previously. Video of these opportunistic dives was analyzed for habitat types, species, and species associations. The species observations from the dives are recorded in this taxonomic guide to provide baseline characterization for this underexplored habitat in the sanctuary. This guide will be amended as more studies are added or completed.
From May 22 to June 4, 2006, NOAA scientists led a research cruise using the ROPOS Remotely Operated Vehicle (ROV) to conduct a series of dives at targeted sites in the Olympic Coast National Marine Sanctuary (OCNMS) with the goal of documenting deep coral and sponge communities.
This document presents the results of the first three monitoring events to track the recovery of a repaired coral reef injured by the M/V Alec Owen Maitland (hereafter referred to as the Maitland) vessel grounding incident of October 25, 1989. This grounding occurred within the boundaries of what at the time was designated the Key Largo National Marine Sanctuary (NMS), now designated the Key Largo NMS Existing Management Area within the Florida Keys National Marine Sanctuary (FKNMS). Pursuant to the National Marine Sanctuaries Act (NMSA) 16 U.S.C. 1431 et seq., and the Florida Keys National Marine Sanctuary and Protection Act (FKNMSPA) of 1990, NOAA is the federal trustee for the natural and cultural resources of the FKNMS.
The U.S. Fish and Wildlife Service initiated this study in 2002 and produced a report on the distribution of eelgrass beds in the eastern portion of Long Island Sound: "Eelgrass Survey for Eastern Long Island Sound, Connecticut and New York" (Tiner, et al. 2003). This survey was intended to be the baseline study for monitoring the status of eelgrass in this area of Long Island Sound. In 2004, the U.S. Environmental Protection Agency provided funding to update this survey in 2005. This report outlines the methods used in the survey, summarizes inventory results, compares the findings with the 2002 survey, and provides detailed maps showing the location of eelgrass (Zostera marina) beds detected during the 2006 survey.
This report focuses on six mitigation hatcheries in the southeastern U.S.: 1) Greers Ferry NFH, Arkansas; 2) Norfork NFH, Arkansas; 3) Dale Hollow NFH, Tennessee; 4) Erwin NFH, Tennessee; 5) Wolf Creek NFH, Kentucky; and 6) Chattahoochee Forest NFH, Georgia. In their capacity as mitigation hatcheries, these facilities provide a variety of environmental and ecological goods and services. This report focuses on a subset of these goods and services: the economic effects of the recreational use of hatchery trout. Aside from the direct fish-related economic effects, the hatcheries also provide additional economic impacts to local communities and adjacent regions through hatchery budget expenditures, including spending related to trout production and the spending of hatchery staff salaries.
This is a new release of the original 1946 edition.
This Final Programmatic Environmental Impact Statement (FPEIS) addresses restoration techniques for anthropogenic physical injury to coral reef resources within Gulf of Mexico and Caribbean waters of the National Marine Sanctuary System (NMSS). The purpose of this document is to present and analyze the current technologies available for effective implementation of restoration to address injury to coral reef resources in these areas of the NMSS; appropriate analysis of the technologies in this document will provide for efficient selection and implementation of action when needed.
This report, A Field Manual for the Use of Antimycin A for Restoration of Native Fish Populations, provides protocols for the use of antimycin A which have been successfully used in restoration efforts within units of the national park system and in national forest and state projects. This document is based upon experiences of biologists from the National Park Service (NPS), the U.S. Fish and Wildlife Service (USFWS) and New Mexico Department of Game and Fish. The authors' hope that the information included in the manual will be applicable to any application of antimycin for the restoration of native fish populations and that it provides fisheries managers with established protocols for safe, effective, and lawful restoration projects utilizing antimycin A.
In May 2005, Coastal and Fisheries staff from Olympic National Park conducted a 3-day inventory of intertidal fishes adjacent to the shoreline of Ebey's Landing National Historical Reserve. Beach seine sampling was employed in all intertidal habitats on both the Admiralty Inlet and Penn Cove shorelines. A total of 31 locations were sampled, resulting in documentation of 28 species. The habitats in both of these regions include sand, gravel, cobble, and boulder beaches. Fish community composition in both regions was dominated by juvenile salmon, particularly chum salmon smolts, however the communities in each region were significantly different from each other. These differences likely reflect the physical habitat differences between the open coastline of Admiralty Inlet and the protected Penn Cove.
Can you imagine life as an oyster farmer? How are tiny baby oysters grown in the water? Find out from eleven-year-old Sam and his twin sister Kate, who take you on a guided tour of their family oyster farm in Maine. Full of fascinating facts as well as vivid photographs and illustrations, Farming on the Sea is author Kellie Peters's fun and educational look at the world of aquaculture that is certain to engage children ages seven- to ten-years-old who are curious about nature and science. It's a one-of-a-kind work of nonfiction that brings this vivid world to life for inquisitive young minds. Young Sam knows all about oyster farming. After all, his parents own a farm in the Damariscotta River, a tidal estuary of midcoast Maine. Now, he shares everything he has learned with children everywhere. First, Sam invites us to join his sister Kate and his dad as they spend a day at an aquaculture hatchery, where tiny baby oysters will be grown to be sent to their farm, Norumbega Oyster. He explains that oysters are mollusks and what it means to be this type of shellfish, including a sketch of the inside of an American oyster. At the shellfish hatchery, he and Kate inspect the large tubes of algae that are fed to mature oysters so they will spawn baby oysters. They also look through a microscope to see the tiny oyster seed. From there, they head out on the water to care for all the oysters on their sea farm, discussing the many creatures of the sea and the land that they see along the way on the coastal waters in the Northeast, including ospreys, ducks, seals, and even whales. Then it's time to get to work, lifting bags of six-month-old oysters out of the water to check them. Dad puts on his SCUBA gear to dive to the bottom of the sea to pick up the three-year-old oysters they are going to sell. Sam explains how to harvest the oysters, which will be delivered to restaurants and seafood shops for everyone to enjoy. Farming on The Sea also includes a glossary; U.S. and world maps that show what aquaculture species are grown where; a detailed diagram of the inside of an oyster; as well as suggested references so children can learn more about the subject. It also features facts that are aligned with the National Science Standards, a table of contents, and an index. Easy-to-read and packed with invaluable information, Farming on the Sea offers a real-life view of the wonderful world beneath the sea that is certain to encourage young readers to cultivate a lifelong love of science, one delicious oyster at a time.
The purpose of this report was to document the status of the marine fish assemblage at KALA in 2010 and examine changes from 2006 to 2010. First, the status of the entire assemblage in 2010 was analyzed for species richness, density, biomass and diversity using spatial distribution maps. Second, the trophic composition of the entire assemblage in 2010 was examined for both density and biomass. Third, the top ten species in 2010 in terms of density and biomass were listed to examine specific components of the assemblage. Finally, trends in the entire assemblage from 2006-2010 were plotted for species richness, density, biomass, and diversity. Figure
Fishermen of Taupo is a book about the fly fishermen of New Zealand's Lake Taupo. It tells the individual stories of twenty Taupo fishermen that I have been fortunate enough to fish with over the years. Taupo is, and still remains, a gem, but with the world getting ever smaller due to air travel, this fishery is fragile. Still it remains, like its trout, wild. It needs protecting before it's lost.
Few people connect Endicott House, the famous conference center of the Massachusetts Institute of Technology, with fishing in Florida, but actually the handsome mansion that has been the site of so many notable meetings is a bricks-and-mortar memorial to one of America's most enthusiastic sports fishermen, Wendell Endicott. This book is his magnum opus, an important piece of Florida history and a lasting contribution to folklore and fishing in the Keys.
The objectives of this study were to (1) determine if a reproducing population of crayfish belonging to the C. acuminatus complex occurs in Valley Creek within VFNHP; (2) conduct a comprehensive survey of Valley Creek within VFNHP and produce a list of all the crayfish species that occur there; and (3) determine the basic life history characteristics (e.g., size structure, sex ratio), reproductive status, and habitat preferences of the crayfish species that occur in Valley Creek within VFNHP. |
