2015 Best Paper of World Aquaculture Magazine

The world’s human population is continuing to increase, with a recent UN projection of global population in 2050 of 9.6 billion. That would be a 33.3 percent increase above the current global population of about 7.3 billion. In many countries, economic conditions are improving; it is anticipated that the middle class will grow by 2.6 billion by 2050 (Ward and Neumann 2012). The middle class has more money to spend and they tend to purchase more food, especially protein, than do poorer people.

Increasing food production will require more land and water, greater intensification, or both. It also will require more nutrients, energy and other resources and cause more negative impacts. It is imperative that the necessary increase in food production be done as efficiently as possible to minimize resource use and wastes. Programs for improving performance and lessening negative environmental impacts of global food production are important to promote more efficient food production [More..]

Modern Aquaculture of Whitefish in the Ob River Basin of Siberia, Russia

The Ob River is one of the largest rivers in the world. The basin area, about 3 million km2, is the largest in Eurasia. The main part of the basin is located in the West Siberian Lowland in territory of the Russian Federation (Fig. 1). The part of the basin with the Russian Federation only that may be used for fishing industry is colossal (156 km2). Stocks of whitefish (Coregonus sardinella, C. autumnalis, C. peled, C. tugun, C. lavaretus pidschian, C. muksun, C. nasus, Stenodus leucichthys nelma) are the main fishery resources of the Ob River basin, considering its climatic features.

Transforming the Journal of World Aquaculture Society in Support of Global Aquaculture

The rate of growth and transformation of global aquaculture has been impressive, averaging 7% annual growth since 2001 (Fig. 1). Moreover, beginning in 2013, the farmed supply of seafood began to exceed that of wild-caught seafood, with aquaculture production supplying 50.9% of total seafood (FAO 2015). The effect of the growth and development of aquaculture globally can also be viewed in terms of the number of aquatic animals for which farmed supply now exceeds that of captured supply (Table 1 presents some examples). The importance and value of such growth is further underscored by the apparent leveling off in the supply of capture-based fisheries species. As global populations continue to increase, aquaculture will only become more important as a solution to meet the increasing demand for protein [More..]

Aquaponics: a Nutrient Dynamic Process and the Relationship to Fish Feeds

Aquaponics is an integrated fish and plant production technology. There are three distinct groups of people adopting this technology: new entrants, existing hydroponic operators and existing recirculating aquaculture system (RAS) operators. The potential for increased income is common to the interests and driving motivations of each group but other motivations, specific to the origin of the discipline involved, are also present. Existing hydroponic operators are primarily interested in accessing an organic nutrient solution for their plants, existing RAS operators are interested in a waste treatment outcome that avoids issues associated with waste releases and new entrants are mainly interested in a localized, niche-scale food production business [More..]

AQUATIC AGRICULTURE: Cultivating Floating Crops on Lakes

Water is the most limiting factor to achieving the large increases in food production needed to satisfy the requirements of a growing and more-demanding population. Crop irrigation uses more than 70 percent of available fresh water worldwide (Madramootoo and Fyles 2010), 73 percent in Nicaragua and 77 percent in Costa Rica (CIA 2014). Rainfed crop production is greatly affected by rainfall variability. Moreover, irrigated and rainfed agriculture are both affected by climate change as it increases the frequency and intensity of extreme events, like droughts and floods, and increases water demand from evapotranspiration.

WAS President

March 2016 President's Column

In the final trimester of my presidency, the Board dedicated a significant amount of time to crafting the new Strategic Plan for WAS. At our midyear meeting in Fortaleza, an ad hoc committee discussed the collective priorities of WAS and how to best address our mission through committees tasked with achieving different outputs under primary and secondary goals. Most of our existing committees mapped nicely to the realigned goals. However, it became clear that some new components need to be developed to address management strategies, human resource issues, and activities associated with conferences and workshops that are not currently addressed by our Conference Committee. An Events Committee will be added to the new plan to ensure that consistent, high-quality activities are implemented across all WAS events. This committee is complementary to the Conference Committee. An ad hoc Human Resources Committee will also be implemented to develop processes for annual evaluations of WAS employees. The first evaluation of our Executive Director was performed in Las Vegas by the President in concert with the EXCOM...
