Interactions Between Short-Beaked Common Dolphin (Delphinus Delphis) And The Winter Pelagic Pair-Trawl Fishery Ff Southwest England (Uk), Marijke N. De Boer, James T. Saulino, Mardik F. Leopold, Peter J.H. Reijnders, Mark P. Simmonds Dec 2014

Interactions Between Short-Beaked Common Dolphin (Delphinus Delphis) And The Winter Pelagic Pair-Trawl Fishery Ff Southwest England (Uk), Marijke N. De Boer, James T. Saulino, Mardik F. Leopold, Peter J.H. Reijnders, Mark P. Simmonds

Mark P. Simmonds, OBE

During offshore and onshore studies (2004 to 2009), the interactions between pair-trawls and short-beaked common dolphins (Delphinus delphis) were studied to better understand the impact of bycatch. A ‘hotspot’ area where pair-trawls overlapped with high dolphin abundance was identified. We made comparisons between boat-based data collected in absence and presence of pair-trawlers. The relative abundance and group-size of dolphins was significantly higher in the presence of pair-trawlers. Dolphins were observed associating with towing and hauling procedures. Significantly, more carcasses occurred in areas with hauling-activity than those without. Body-temperatures obtained from carcasses found near operating pair-trawlers indicated that bycatch mostly occurred …

El modelo usado por la antigua red, en base a carpetas compartidas y repositorios, para desarrollar nuevos contenidos y transmitirlos se agota. En éste libro se propone recordar que si nadie visita tu página, que si uno se limita a hablar de si mismo sin formular preguntas, que si por el contrario facilita respuestas y las promociona construyendo algo excitante, si establece objetivos trimestrales, y si siempre tiene un horizonte a largo término. Entonces accede a las nuevas y fáciles de usar herramientas que se conocen como Web 2.0, las cuales conectan gente dando lugar a redes sociales, colaborando y …


The Shellfish Corner -- Shellfish And The Problem Of Ocean Acidification, Michael A. Rice Sep 2014

The Shellfish Corner -- Shellfish And The Problem Of Ocean Acidification, Michael A. Rice

Michael A Rice

The acidification of the world's oceans due to increasing atmospheric carbon dioxide concentrations is creating a problem in the dissolution of larval shells of mollusks and creating problems for shellfish hatcheries. Hatcheries can mitigate the problem by treating incoming seawater with alkaline sodium carbonate, but there is evidence that acidic sediments in some locations are a source of considerable post-settlement loss of newly set juveniles.


Microalgae In Eastern Pacific White Shrimp Hatcheries: A Review On Roles And Culture Environments, Wa Iba, Michael A. Rice, Gary H. Wikfors Aug 2014

Microalgae In Eastern Pacific White Shrimp Hatcheries: A Review On Roles And Culture Environments, Wa Iba, Michael A. Rice, Gary H. Wikfors

Michael A Rice

Demand for shrimp, particularly the eastern Pacific white shrimp Litopenaeus vannamei (Boone 1931), will continue to increase in Asian and worldwide seafood markets. Providing shrimp farms with a robust, healthy, and continuous supply of shrimp seed is a challenge that must be addressed to meet the demand. Shrimp feed during hatchery production still relies on live microalgae, despite many years of effort to find suitable full or partial-replacement diet alternatives. Successful mass production of microalgae for hatchery feed to obtain good quality shrimp seedstock depends on a number of environmental factors that determine the growth and nutritional values of various …


Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra Aug 2014

Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra

Ganesh Chandra

Assam is endowed with copious aquatic wealth in the form of beels, swamps, ponds and rivers. The floodplain wetlands (beels) extending over one lakh hectare, constitute the most important fishery resource of the state. The beels are considered as one of the most productive ecosystems owing to their characteristic interactions between land and water system. These wetlands are the common property resource and under different management regimes. These wetlands are under various management regimes, i.e., private management (individuals and groups), fishermen cooperative management, Community-based fisheries management (decentralized management, Government works as facilitator) and open access. Most of the unregistered beels …


Extension Programming In Support Of Public Policy For The Management Of Aquaculture In Common Water Bodies, Michael A. Rice Jun 2014

Extension Programming In Support Of Public Policy For The Management Of Aquaculture In Common Water Bodies, Michael A. Rice

Michael A Rice

Many countries of Asia, including Indonesia, have experienced the problem of hypoxic fish kills among fish in netpens and fish corrals in various publicly-held water bodies. Fish farming in enclosures in public water bodies attractive because of low overhead costs in comparison to farming the identical species in constructed ponds. But aerobic bacterial degradation of feed and fish feces in common waters can lead to oxygen depletion, thus causing fish kills. Mass-balance and ecological carrying capacity models and education through and extension programming can be used to inform policy makers as to the maximum biomass of farmed fish allowable before …

Alewives: Feast Of The Season, Catherine V. Schmitt

Catherine Schmitt

Alewives are sea-run, or diadromous, fish that spend most of their lives in the Atlantic Ocean but return as adults to coastal rivers in spring to spawn in freshwater streams and ponds. This article in Maine Boats, Homes, & Harbors magazine discusses the natural and cultural history of Maine's native runs of alewives and other sea-run fish.

Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric Schultz, Jose Pereira, Peter Auster Jan 2014

Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric Schultz, Jose Pereira, Peter Auster

Jose J Pereira

Winter flounder (Pseudopleuronectes americanus) come inshore during the late winter and early spring to lay their eggs in shallow bays and estuaries along the coast. Unlike most fish eggs, which are buoyant, these eggs are demersal and sink to the seafloor. This makes them vulnerable to burial from various types of natural and human caused disturbances (e.g., storms, mobile fishing gear, maintenance dredging). Our objective was to map spawning areas in two harbors and search for generalities among these sites that would allow us to predict where winter flounder might spawn in other areas. This would allow managers to avoid …


Frequency-Dependent Mate Selection In The Guppy (Poeciliidae: Poecilia Reticulata), Andre Porter, Jack Frankel Dec 2013

Frequency-Dependent Mate Selection In The Guppy (Poeciliidae: Poecilia Reticulata), Andre Porter, Jack Frankel

Jack Frankel

Heterogeneity within a population enhances its long-term survival. A fundamental method of maintaining population heterogeneity is the retention of rare or uncommon phenotypes by selective mating strategies. Employing two color morphs, red tuxedo and red, of the guppy (Poecilia reticulata, Poeciliidae), this study was designed to investigate whether P. reticulata females would preferentially seek out heterogeneous groupings of males exhibiting two color morphs. Adult female guppies were exposed simultaneously to two groups of males (n=10); one comprised of only the tuxedo color morph (n=5) and the other of both color morphs (n=5). For the latter group, the ratio of males …


The Centennial Of The Smith-Lever Act And Aquaculture Extension, Michael A. Rice Dec 2013

The Centennial Of The Smith-Lever Act And Aquaculture Extension, Michael A. Rice

Michael A Rice

May 8, 2014 marked the centennial of the landmark Smith-Lever Act in the United States that created the Cooperative Extension service at Land Grant Universities nationwide. Major contributors to the 1914 Act were Seaman A. Knapp and Kenyon L. Butterfield. A half century later the Sea Grant College Program was proposed by Athelstan F. Spilhaus expanding Extension programming to the sea. Together these two programs have been a major force in promoting the growth of the aquaculture industry in America.
