Introducing the Editor in Chief

The World Aquaculture Society and Wiley are delighted to introduce Dr Carole Engle as the Editor-in-Chief for the Journal of the World Aquaculture Society.

Carole Engle

Carole Engle has devoted more than 35 years to aquaculture research, extension, and teaching. She has a combined 49 years of editorial experience, serving as Editor-in-Chief of Aquaculture Economics and Management in addition to serving on the editorial boards of the Journal of the World Aquaculture Society and the Journal of Applied Aquaculture. She is a past-President of the U.S. Aquaculture Society and the International Association of Aquaculture Economics and Management and is a current Director on the Board of the World Aquaculture Society. Engle was on the faculty of the University of Arkansas at Pine Bluff (UAPB) for more than 27 years and, as Director of the Aquaculture/Fisheries Center and Chairperson of the Department of Aquaculture and Fisheries.

Comparison of protective efficacy between formalin-killed and aroA gene-knockout Vibrio anguillarum vaccines in olive flounder, Paralichthys olivaceus
S. H. Choi, D. S. Kim and K. H. Kim
Journal of the World Aquaculture Society 48(6):854-859

Development of effective vaccines has been critical to the growth and development of aquaculture. Choi et al. (2017) showed greater effectiveness of an aroA gene-knockout Vibrio anguillarum vaccine in olive flounder, Paralichthys olivaceus, (the most important commercial farmed fish in Korea) as compared to the currently available formalin-inactivated vaccines.

Locally grown oysters in Hawai‘i: chef preference and local premium?
J. Q. Chen, M. C. Haws, Q. S. W. Fong and P-S. Leung
Journal of the World Aquaculture Society 48(6):972-980

Demand for locally-grown food appears to have increased, but there is a lack of research data on preferences and price effects of locally grown fish and shellfish. Chen et al. (2017) found that chefs in Hawai’i who had oysters on their menus preferred fresh and locally-grown oysters, even on an as-available basis, and were willing to pay a price premium of $5.25 per dozen oysters.

Design characteristics of spiral aerator
S. M. Roy, S. Moulick and B. C. Mal
Journal of the World Aquaculture Society 48(6):898-908

A variety of commercially available aerators are used in aquaculture throughout the world. Given that aeration rates have generally increased, improvements in aerator design have potential to improve production efficiency. Roy et al. (2017) evaluated the performance of a new spiral aerator design and identified the least-cost rotational speed under differing pond conditions.

Effects of dietary lipids on the growth performance, survival, and digestive enzymes of juvenile cuttlefish, Sepia lycidas
Q. Han, Y. Wang, T. Lv, Q. Han and X. Jiang
Journal of the World Aquaculture Society 48(6):963-971

Cuttlefish are of commercial importance in Japan and China, but work is needed to fully define nutritional requirements for the various species of interest. Han et al. (2017) examined effects of dietary lipids on growth, survival, and digestive enzymes of juvenile cuttlefish, Sepia Lycidas, and suggested an optimal dietary lipid level of 9.56%.

An analysis of nearly one billion dollars of aquaculture grants made by the US federal government from 1990 to 2015
Love, D.C., I. Gorski, and J.P. Fry
Journal of the World Aquaculture Society 48(5):689-710

Investment in research is critical to on-going innovations that contribute to growth and development of aquaculture. Love et al. (2017) analyzed U.S. federal grant funding over a 25-year period. Species, topics, and disciplines that received the most grant support were identified. The analysis reported an approximately 37-fold return on the investment in aquaculture research.

Methionine Requirement for Juvenile White Seabass, Atractoscion nobilis, Using Nonlinear Models
Salze, G.P., D.A. Davis, D.O. Jirsa, and M.A. Drawbridge
Journal of the World Aquaculture Society 48(5):729-740

Methionine is often the first limiting amino acid in plant protein sources such as soybeans, and determination of its requirements for important commercial species such as white seabass is critical to be able to formulate tailored, practical feeds. Salze et al. (2017) concluded that the methionine requirement for juvenile white seabass was 0.88%.

Innovative Egg Custard Formulation Reduced Rearing Period and Improved Survival of Giant Freshwater Prawn, Macrobrachium rosenbergii, Larvae
Sin, N.N.N. and R. Shapawi
Journal of the World Aquaculture Society 48(5):751-759

While Artemia sp. are used widely around the world as live feeds for larvae, its high cost is problematic. Sin and Shapawi (2017) found that readily available, lower-cost ingredients such as poultry byproduct meal and palm oil use in an egg custard formulation reduced the rearing period and improved survival of freshwater prawn, Macrobrachium rosenbergii, larvae, when combined with Artemia sp.

Imidazole-dicarboxylic Acid Nickel Complex as a Novel Grafting Agent for Pearl Oyster, Pinctada martensii
Ji, L., W. Song, J. Guo, Y. Wang, and L. Cai
Journal of the World Aquaculture Society 48(5):711-717

In pearl production, a critical step is the surgical implantation of a nucleus and a piece of mantle tissue into the gonad of a recipient pearl oyster. Ji et al. (2017) found that a novel synthesized grafting agent, imidazole-dicarboxylic acid nickel complex, has potential to promote wound healing after mantle implantation, promote nacre secretion, and enhance oyster immunity
