Under the IIFET 2018 Special Session “Tools for Stock Assessment, Economic Fishery Analysis, and Risk Assessment for Sustainable Management Strategies of Data Poor Stocks in Mixed, Small Scale and Indigenous Fisheries” a number of stakeholder presentations addressed the current status, challenges, needs and future perspectives for implementation of management and...
Bacteria are abundant in marine environments. They play important roles in nutrient cycling and form symbiotic interactions with eukaryotes. However, the vast majority of bacterial taxa are difficult to maintain in laboratory cultures, meaning that most microbiological research of the past century has focused on a small subset of bacteria....
The purpose of this paper is to describe the
application of expert system concepts to cartographic
problems. Expert systems, a subfield of artificial
intelligence, are computer programs based on knowledge and
symbolic reasoning. The basic principles of expert systems
will be explained. Areas of cartography that are most
suitable for...
Increased sales of surimi seafood, with the majority as crabstick in the United States indicates that surimi based products are becoming more popular. With growing popularity, there is increased competition for market share. Under these circumstances, some companies may be willing to sacrifice product quality in order to facilitate manufacture...
The collection, evaluation, and organization of spatial information is instrumental to the
successful development and execution of planning policies and management programs.
Geographic Information Systems (GIS) provide the technology to integrate varying
informational needs into a single relational database for ease in data retrieval and
analysis. The use of a...

Training high school students to conduct field mapping and data
collection of wildlife habitat on public lands produces important data for
local government geographic information systems and introduces students
to the field of geography. However, the positional accuracy of the spatial
data is important for use in a GIS, as...
Global change and its associated temperature increase has directly or indirectly changed the distributions of hosts and
pathogens, and has affected host immunity, pathogen virulence and growth rates. This has resulted in increased disease in
natural plant and animal populations worldwide, including scleractinian corals. While the effects of temperature increase...

Mapped cpDNA restriction site characters were analyzed cladistically and the resulting phylogenetic hypotheses were used to test monophyly and relationships of the infrageneric classification of Lathyrus (Fabaceae) proposed by Kupicha (1983, Notes from the Royal Botanic Garden Edinburgh 41: 209–244). The validity of previously proposed classification systems and questions presented...
Branch campuses play an important part in postsecondary degree attainment by providing place-bound students from diverse socioeconomic backgrounds in different geographical regions access to education that is convenient. Their heterogeneousness structures, including enrollment size, communities, and populations served, are not accurately reflected in the majority of the research. Currently, there...
Cell-to-cell communication by chemical signals, termed quorum sensing (QS), is a common regulatory scheme in the microbial world. Pseudomonas aeruginosa¸ an opportunistic pathogen of burn wounds and cystic fibrosis lungs, uses QS to control the expression of hundreds of genes, particularly those necessary for population level benefits such as biofilm...

In the wild, marine fish larvae feed on copepods and other planktonic organisms.
Copepods are often considered the "gold standard" for meeting the nutritional needs of cultured marine fish larvae; however, in captivity, marine fish larvae are generally fed cultured live prey, i.e. rotifers (Brachionus plicatilis) and/or Artemia sp., until...
