Crop production systems have adopted cost-effective, sustainable and environmentally friendly agricultural practices to improve crop yields and the quality of food derived from plants. Approaches such as genetic selection and the creation of varieties displaying favorable traits such as disease and drought resistance have been used in the past and continue to be used. However, the use of biostimulants to promote plant growth has increasingly gained attention, and the market size for biostimulants is estimated to reach USD 4.14 billion by 2025. Plant biostimulants are products obtained from different inorganic or organic substances and microorganisms that can improve plant growth and productivity and abate the negative effects of abiotic stresses. They include materials such as protein hydrolysates, amino acids, humic substances, seaweed extracts and food or industrial waste-derived compounds. Fish processing waste products have potential applications as plant biostimulants. This review gives an overview of plant biostimulants with a focus on fish protein hydrolysates and legislation governing the use of plant biostimulants in agriculture.
Promote and facilitate the contribution that fisheries and aquaculture can make to economic growth.
Over 80 local farmers, business leaders, government representatives, and interested members of the general public participated in the first Opportunities in Aquaculture Workshop, at the World Resort Saipan on July 10-11, 2008. The workshop, the first of its kind on Saipan, was conducted by Oceanic Institute (OI) and the Northern Marianas College Cooperative Research, Extension & Education Service (NMC-CREES), with funding from CTSA. The goal of the workshop was to educate residents of the Commonwealth of the Northern Mariana Islands (CNMI) and Guam about the potential of aquaculture in the region. In addition, the workshop provided residents with information about region-specific concerns and aquaculture-related regulation and permitting issues.
Dr. Isabella Kauakea Yau Yung Aiona Abbott will forever be an icon in Hawai‘i for her academic achievements, revolutionary seaweed research, various accolades, and over a hundred limu-related publications. However, it’s the values she embodied as a person that make her a timeless inspiration to Native Hawaiians and to the entire state of Hawai‘i.
Dr. Abbott grew up in an era when Native Hawaiians confronted harmful misconceptions and offensive stereotypes, and a time when women were seen as lesser than men. She rejected those narratives and instead lived authentically as a passionate young Native Hawaiian woman who became the world’s leading expert on algae in the Pacific. She always credited her love for algae to the limu lessons she learned from her mom while playing on the beach as a child. Her upbringing led her to understand that Hawaiians have always been scientists. She uplifted Hawaiian culture and the relationship that Western science has with Hawaiian culture throughout her algal research in Hawai‘i and California. She inspired University of Hawai‘i at Mānoa to create a Hawaiian ethnobotany bachelor’s degree and touched the lives of countless students through her teachings. She once said in an interview, “Hawaiian culture is unbelievably sophisticated,” and every day she embodied the meaning of those words.
Dr. Abbott is a treasure to scientists, Hawai‘i, Native Hawaiians, and anyone told that they can’t do something because of their background. She will always be remembered and honored as one of Hawai‘i’s most inspirational leaders.

The first U.S. National Report on Aquaculture for the 41stU.S. Japan Natural ResourcesPanel on Aquaculture overviews major policy items, current trends in aquaculture production, andother important developments affecting contemporary U.S. aquaculture. Policy- April 2013 saw the release of the National Ocean Policy Implementation Plan (NOP-IP), a document to translate President Obamaʼs 2010 National Ocean Policy (Executive Order13547 --Stewardship of the Ocean, Our Coasts, and the Great Lakes) to specific federal actions.Aquaculture featured prominently in the Implementation Plan. The Joint Sub-committee onAquaculture (JSA) was re-named the Interagency Working Group onAquaculture (IWG-A),and was tasked with identifying and supporting milestones in the NOP-IP. The NOP-IP alsosupported the National Shellfish Initiative to increase shellfishproduction and restoration in U.S.waters. NOAA and the Gulf of Mexico Fishery Management Councilare working on a FisheryManagement Plan to permit aquaculture in federal waters in theGulf of Mexico. The U.S.currently does not have a framework to permit aquaculture in the EEZ, and this would be a firstfor the U.S. if it goes into effect. Developments- For the first time in some years, in 2013 many new sites for shellfish aquaculturehave been permitted. This is attributed to increased interest in shellfish aquaculture, particularlyin the northwest and northeast, federal interagency and state efforts on behalf of the WashingtonShellfish Initiative, and state-level successes at streamliningpermitting. In September 2013,the California Shellfish Initiative was launched. A program isunderway to permit and restoreHawaiian fishponds, a form of traditional Hawaiian aquaculture,for cultural heritage, subsistence,and possibly commercial production. Production Trends- Aquaculture production in the U.S. is largely composed of catfish, crawfish,trout, salmon, oysters, mussels, clams, tilapia, and shrimp. For the 15-year period from 1996-2011,the value of U.S. aquaculture showed 3% average year-over-yeargrowth, though total volumefell by an average of 0.5%. Mariculture (salmon and shellfish),on the other hand, showed robust4% by volume and 5% by value year-over- year average growth inthe same period. 2011 is themost current year published aquaculture statistics are available. From 2010 to 2011, total U.S.aquaculture went down -18.8% by volume (to 277,335 metric tons)but grew 4.2% by value (to1.34billion dollars). From 2010 to 2011 mariculture decreasedby -12.4% by volume (to 35,739metric tons) while growing 0.3% by value (to 314 million dollars). However, in the previous yearfrom 2009-2010, mariculture grew 21.6% by volume (to 40,823 metric tons) and 28.5% by value (to312 million dollars). Most of the growth in value for marine aquaculture was from salmon (Salmosalar) and oyster (mainly Crassostrea gigas and Crassotrea virginica) production.
The Task Force In response to the growing problem of invasive species, in 2003, Governor Pataki signed legislation sponsored by Senator Marcellino and Assemblyman DiNapoli. Chapter 324 of the Laws of New York of 2003 called for an Invasive Species Task Force to explore the invasive species issue and to provide recommendations to the Governor and the Legislature by November 2005. The statute describes the intended membership of the Task Force and directs that it be co-led by two New York State agencies:
Department of Environmental Conservation (DEC)
Department of Agriculture and Markets (DAM)
Other members of the Task Force include:
New York State Department of Transportation
New York State Thruway Authority (and Canal Corporation)
New York State Museum (and Biodiversity Research Institute)
New York State Office of Parks, Recreation and Historical Preservation
New York State Department of State Adirondack Park Agency
New York Sea Grant
Cornell University
Invasive Plant Council
The Nature Conservancy
New York State Natural Heritage Program
New York State Farm Bureau
Empire State Marine Trades Association
New York State Nursery and Landscape Association
The Task Force has taken numerous steps toward accomplishing its mission. It first established a Steering Committee to oversee the day-to-day work of the Task Force. Early on, it arranged for the whole Task Force to consult with the Executive Director of our federal counterpart, the National Invasive Species Council. The next task was to design and conduct an in-depth survey of all Task Force member organizations to assess concerns, capabilities, and needs. Then, the Task Force established several smaller teams to investigate in detail, to analyze existing efforts, to identify needs, and to develop recommendations. Each team was designed to pull together organizations that share a common area of interest or expertise. The Task Force reached out to numerous stakeholders to invite them to participate as members of these teams.
The Task Force has met at various locations around New York State. These vi meetings were open to the public and dates, times and locations were announced in the Environmental Notice Bulletin. At most meetings, members visited sites of ongoing invasive species management projects. Formal public review of the Draft Report of the Invasive Species Task Force will be accomplished through a combination of both in-person public meetings and internet communication. It will be completed during the summer of 2005.
Nutrient bioextraction using Gracilaria tikvahiae McLachlan was tested at two sites: one off Fairfield, CT (LIS), and the other at the mouth of the Bronx River Estuary (BRE), during the summer and fall of 2011 and 2012. The estimates of nitrogen (N) removal by Gracilaria over a 90-day growing season were up to 28 and 94 kg N ha-1 at the LIS and BRE sites, respectively. In July 2012, Gracilaria grew up to 16.5% day-1 at BRE and 4.8% day-1 at the LIS site. Tissue N contents at the same periods were 3.7% (BRE) and 1.5% (LIS), respectively. These results demonstrate rapid assimilation of nutrients fueling the growth of new Gracilaria tissue at the BRE site, while nutrients appeared to limit growth at the LIS site during the summer months. The estimated C removal by Gracilaria at the BRE and LIS sites were up to 300 kg ha-1 (LIS) and 727 kg ha-1 (BRE), respectively. The potential economic values of N and C sequestration for the period examined in this study were as high as $311 (LIS) and $940 ha-1 (BRE) for N, and $5.51 (LIS) and $13.32 ha-1 (BRE) for C if seaweed aquaculture would be included in Connecticut's Nitrogen Trading Program. This represents a potential additional economic incentive for seaweed growers, beyond the direct value of seaweed products. The findings in this study showed that seaweed (Gracilaria) aquaculture can be a useful technique for nutrient bioextraction in urbanized coastal waters, such as the estuaries of New York City (BRE) and Long Island Sound.
