3, Kb1-5, and Kb2-6, were evaluated under controlled conditions. A batch culture experiment of these
strains except Kb2-6 was conducted for 15 days under salinity levels of 20, 25, 30 and 35 gL-1. Tetraselmis
chui, Tisochrysis lutea and Chaetoceros neogracile were also culture and used as the growth references. Cell
density was measured every day and cell size was measured from 50 live cells during the logarithmic ...


Freshwater Aquaculture And Its Permitting In Rhode Island: Two Case Studies, Michael A. Rice, Joseph B. Haberek, David Beutel Nov 2018

Freshwater Aquaculture And Its Permitting In Rhode Island: Two Case Studies, Michael A. Rice, Joseph B. Haberek, David Beutel

Michael A Rice

In Rhode Island permits to conduct aquaculture, including freshwater aquaculture, are issued by the Coastal Resources Management Council (CRMC) as the designated lead agency by state law. However, by Rhode Island law, aquaculture is considered a form of agriculture. It is the responsibility and duty of the state aquaculture coordinator in CRMC to receive aquaculture applications and coordinate the review of these applications through the multiple federal, state and local agencies that hold regulatory jurisdiction. Since most freshwater aquaculture is conducted on private lands rather than in public trust waters of the state, there is no leasing review. If the ...

The Shellfish Corner: The Promises Of Aquaculture And Caveat Emptor, Michael A. Rice Jul 2018

The Shellfish Corner: The Promises Of Aquaculture And Caveat Emptor, Michael A. Rice

Michael A Rice

For at least five decades in America there has been a fascination about aquaculture as a means to "feed the world" in a sustainable way. Periodic reporting by the popular press has generated excitement about the potential of aquaculture among the general public and often this excitement often leads to unrealistic expectations and engagement in unsound business decision making by the novices in the field. Aquaculture entrepreneurs and investors are urged to exercise good judgement by sticking with with fundamentally sound business planning while maintaining realistic business expectations.


The Shellfish Corner: Shellfish Aquaculture In The Commons, Michael A. Rice Mar 2018

The Shellfish Corner: Shellfish Aquaculture In The Commons, Michael A. Rice

Michael A Rice

The major common denominator of shellfish aquaculture in coastal or estuarine waters worldwide is that most culture operations are conducted in common or public trust waters, necessitating constant interaction in the political arena with other competing interests. As a matter of practicality, the best systems for managing aquaculture lease policy in an equitable manner are on a local enough scale to facilitate stakeholder involvement, and to allow aquaculturists to organize into professional trade organizations so that the collective interest of the industry is heard in the process.


The Shellfish Corner: Cap And Trade Systems With Shellfish May Be Good For The Economic Bottom Line, Michael A. Rice Dec 2017

The Shellfish Corner: Cap And Trade Systems With Shellfish May Be Good For The Economic Bottom Line, Michael A. Rice

Michael A Rice

The development of a traditional form of Integrated Multi-Trophic Aquaculture (IMTA) in the Dagupan City Estuary system in the Philippines is based upon different producers each focusing on individual species rather than individual producers producing multiple species with very different market values. The long-term success of such a system requires attention to local marine spatial planning and enforcement of caps on forms of feed-based (net pen or fish cage) aquaculture systems.

The Luther H. Blount Shellfish Hatchery at Roger Williams University was begun in 2004 in an effort to restore shellfish beds to Rhode Island's Narragansett Bay. Over the years by way of the philanthropy of the Blount Family, the hatchery has grown and has served to train many professional shellfish hatchery personnel, and has served as a support facility for shellfish disease and nutrition research.


The Shellfish Corner: Aquaculture Of Exotic Shellfish Species, Michael A. Rice May 2016

The Shellfish Corner: Aquaculture Of Exotic Shellfish Species, Michael A. Rice

Michael A Rice

Successful commercial aquaculture operations have grown in the Pacific Northwest and the Canadian West Coast on two exotic species Crassostrea gigas and Tapes philippinarum introduced from Japan during the 20th Century. Introduction of the Asian oyster C. ariakensis was proposed as a means for recovering distressed oyster fisheries in Chesapeake Bay, but it was not pursued after extensive public review deemed the practice too risky. However due to increased global shipping, exotic bivalves are being transferred worldwide. The recent introduction of a Western Hemisphere mussel Mytella charruana into the Philippines provides a good case study of shellfish aquaculture industry opportunities ...


The Shellfish Corner -- Water Quality And Culture Of Shellfish In Prohibited Waters, Michael A. Rice Jan 2016

The Shellfish Corner -- Water Quality And Culture Of Shellfish In Prohibited Waters, Michael A. Rice

Michael A Rice

In the United States, water quality standards for shellfishing and shellfish aquaculture waters have been governed since 1925 by the National Shellfish Sanitation Program (NSSP) first administered by the United States Public Health Service. With the greater popularity of aquacultured shellfish in the United States and the growth of market demand, seed availability is cited as one of the most pressing issues for the industry. The early recognition by ISSC of shellfish seed under certain conditions as being exempt from NSSP water quality classification requirements has already removed one of the largest regulatory barriers to expansion of seed production in ...


The Shellfish Corner: Filter Feeding Bivalves As Processors Of Coastal Waters, Michael Rice Aug 2015

The Shellfish Corner: Filter Feeding Bivalves As Processors Of Coastal Waters, Michael Rice

Michael A Rice

Bivalves have a profound role in controlling the boom and bust cycles of seasonal phytoplankton blooms, and the increased rates of sediment deposition to the bottom by bivalves are an important "coupler" between the water column and the bottom that stimulates the rate of decomposition and other processes in the sediments.


Establishing A National Shellfish Sanitation Program In The Gambia, West Africa, Michael A. Rice, Foday Conteh, Karen Kent, Brian Crawford, Banja Bamba, Fatou Janha, Ismaila Bojang Jul 2015

Establishing A National Shellfish Sanitation Program In The Gambia, West Africa, Michael A. Rice, Foday Conteh, Karen Kent, Brian Crawford, Banja Bamba, Fatou Janha, Ismaila Bojang

Michael A Rice

A successful national program to assure sanitary quality of molluscan shellfish requires a multi-disciplinary and multi-agency governmental training, data collection, policy development and management effort in collaboration with members of the shellfish industry. The Tanbi Wetlands and other estuaries of Gambia support shellfisheries for oysters, Crassostrea tulipa, and the senile ark, Senelia senilis, conducted by the TRY Oyster Women’s Association. With low shellfish prices and a small local market, a Gambian National Shellfish Sanitation Program (GNSSP) was begun as a means to boost consumer confidence and allow market access to Gambia’s robust seasonal international tourism trade. Gambian officials ...

Isolation And Characterization Of Microalgae Strains For Live Food In Sulawesi, Indonesia, Wa Iba, Michael Rice May 2015

Isolation And Characterization Of Microalgae Strains For Live Food In Sulawesi, Indonesia, Wa Iba, Michael Rice

Michael A Rice

Four strains of diatoms were isolated from the waters of Kendari Bay in Southeast Sulawesi, Indonesia, including strains of Melosira moniliformis, Chaetoceros, sp. and a larger species that is likely to be Tetraselmis weissflogii. Isolated strains have exhibited a wide range of salinity tolerances in the 20 to 35 psu range. Strains of isolated phytoplankton were able to reach high densities consistent with strains suitable for use as aquaculture feeds. One strain Kbl-3 attained lipid content of 22.3 percent per gram dry weight at salinity of 35 psu, suggesting that it may be a good feed for shrimp larvae ...


The Shellfish Corner--Shellfish Sanitation And The Price Of Shellfish, Michael A. Rice Jan 2015

The Shellfish Corner--Shellfish Sanitation And The Price Of Shellfish, Michael A. Rice

Michael A Rice

Prices of raw molluscan shellfish in different countries around the world are tied to perceived risk of becoming ill if consumed. Wholesale prices of oysters in the southern New England from 1880 to 2010 are analyzed in relation to introduction of flush toilets and sewer systems in the early 20th Century, the initiation of the US National Shellfish Sanitation Program in 1925 and renewed consumer interest in consuming raw shellfish in the latter half of the 20th Century.


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 ...


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 ...


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.

Bacterial Community Profiling Of The Eastern Oyster (Crassostrea Virginica): Comparison Of Culture-Dependent And Culture-Independent Outcomes, Kenneth J. La Valley, Steve Jones, Marta Gomez-Chiarri, Joseph Dealteris, Michael A. Rice

Michael A Rice

Tissue-associated bacterial community profiles generated using a nested polymerase chain reaction–denaturing gradient gel electrophoresis (DGGE) approach and culture-dependent and culture-independent isolation techniques were compared. Oyster samples were collected from 2 harvest areas along the coast of Maine, in the United States. Profiles from both isolation strategies were evaluated using Sorensen’s index of similarity and cluster analysis of gel banding patterns. Cultureindependent profiles were further evaluated using the Shannon diversity index. In general, the culture-dependent strategy resulted in a greater number of bands within a profile. BacterialDGGEprofiles were found to be highly similar within an isolation strategy, with a ...

Gonadal Cycle Of Northern Quahogs, Mercenaria Mercenaria (Linne, 1758), From Fished And Non-Fished Subpopulations In Narragansett Bay, Dora Marroquin-Mora, Michael Rice

Michael A Rice

To determine if population density in areas closed to fishing in Narragansett Bay is causing differences in the reproductive potential of the organisms, this study used two approaches to determine the reproductive condition of the animals. The first approach consisted in employing a gravimetric condition index (CI) to evaluate the general condition of quahogs from nine different sites, 3 sites open conditionally for fishing (conditional areas) and 6 sites closed to fishing. The second approach was a determination of gonadal index (GI) of a subset of the sample sites, by histological observation of gonadal tissue sections. Initial sampling included determination ...


Modified Taylor Float System For Culturing Oysters In The Gambia, Michael A. Rice Dec 2012

Modified Taylor Float System For Culturing Oysters In The Gambia, Michael A. Rice

Michael A Rice

This monograph is a report of trials to grow oysters, Crassostrea tulipa, in Taylor Float plastic mesh culture bags in oyster harvesting sites in Gambia, West Africa. Oysters grew well in the gear, but adoption of the gear by local oyster farmers would be difficult due to the relatively high cost of the gear in relation to the value of oysters cultured within. Economic analysis suggested an eight-year investment payback to recover costs of the gear.


Report On Sanitary Shoreline Survey Within The Tanbi Wetlands National Park And Other Shellfish Harvesting Communities, The Gambia May 2012

Report On Sanitary Shoreline Survey Within The Tanbi Wetlands National Park And Other Shellfish Harvesting Communities, The Gambia

Michael A Rice

Emphasis is placed on the sanitary control of shellfish because of the direct relationship between pollution of shellfish growing areas and the transmission of diseases to humans. Shellfish borne infectious diseases are generally transmitted via a fecal - oral route. To accurately assess waters for shellfish harvesting, an evaluation of the pollution sources that are likely to affect the area is required by the NSSP. The shoreline survey is conducted of the shellfish growing area shoreline and estuary to locate pollution sources that could have an effect on the water quality of the area. The shoreline survey team visited 15 oyster ...

A Brief History Of The American Fish Culture Company 1877-1997., Michael A. Rice

Michael A Rice

The American Fish Culture Company operated for nearly 120 years from 1877-1997 in Carolina, Rhode Island growing three species of trout under the under the direction of several generations of the Hazard family of Peace Dale, Rhode Island. The company was one of the first trout producers in the United States, and was considered the largest fish farm in the country by the early 1920s. Major innovations of the company included early adoption of pelleted feeds, and the introduction of photoperiod manipulation to spawn fish out of season. The company ultimately failed due to intense competition from larger producers in ...
