Le Bris), http://umaine.edu/wahlelab/current-projects/american-lobster-settlement-index/ Several months now into the COVID-19 pandemic, we can only look back to the 2019 fishing year with some nostalgia. In calendar year 2019, Canadian lobster landings continued to boast near all-time highs. And while US landings have slipped a bit from their own historic highs, much of those losses have been offset by continued high value. That is, until now. All that changed almost overnight with the onset of the pandemic, as demand for lobster plummeted with shuttered restaurants and overseas commerce, dragging down the price of lobster, much to the distress of fishing communities up and down the coast. As we enter the 2020 summer fishing season, the lobster industry grapples to find a new normal as it accommodates health protocols, readjusts markets and scales back revenue expectations. In kind, state and federal marine resource monitoring programs are equally rethinking sampling programs under shrinking tax revenues and new safety standards. Last year’s Update examined how well ALSI predicted trends in the fishery from Fundy to Rhode Island.

Learning in Stomatopod Crustaceans
International Journal of Comparative Psychology, 2006, 19 , 297-317. Copyright 2006 by the International Society for Comparative Psychology Learning in Stomatopod Crustaceans Thomas W. Cronin University of Maryland Baltimore County, U.S.A. Roy L. Caldwell University of California, Berkeley, U.S.A. Justin Marshall University of Queensland, Australia The stomatopod crustaceans, or mantis shrimps, are marine predators that stalk or ambush prey and that have complex intraspecific communication behavior. Their active lifestyles, means of predation, and intricate displays all require unusual flexibility in interacting with the world around them, imply- ing a well-developed ability to learn. Stomatopods have highly evolved sensory systems, including some of the most specialized visual systems known for any animal group. Some species have been demonstrated to learn how to recognize and use novel, artificial burrows, while others are known to learn how to identify novel prey species and handle them for effective predation. Stomatopods learn the identities of individual competitors and mates, using both chemical and visual cues. Furthermore, stomatopods can be trained for psychophysical examination of their sensory abilities, including dem- onstration of color and polarization vision. These flexible and intelligent invertebrates continue to be attractive subjects for basic research on learning in animals with relatively simple nervous systems. Among the most captivating of all arthropods are the stomatopod crusta- ceans, or mantis shrimps. These marine creatures, unfamiliar to most biologists, are abundant members of shallow marine ecosystems, where they are often the dominant invertebrate predators. Their common name refers to their method of capturing prey using a folded, anterior raptorial appendage that looks superficially like the foreleg of a praying mantis.

Krill Oil and Astaxanthin
Krill Oil and Astaxanthin Krill are small reddish-color crustaceans, similar to shrimp, that abound in cold Arctic waters. They survive in such cold, frigid temperatures because of their natural anti- freeze, the polyunsaturated fatty acids EPA and DHA. EPA and DHA are bound to molecules called phospholipids (especially phosphatidyl choline) that act to help transport nutrients into cells and change the structure of animal cell membranes. Studies show that these combined fatty acids have better absorption into the cell membranes throughout the body, especially the brain, as compared to other types of fish oils. Although it has less EPA/DHA content than most fish oils, krill oil seems to be almost twice as absorbable. Unlike fish oil, krill oil also contains a very potent antioxidant, astaxanthin, which helps prevent krill oil from oxidizing (turning rancid). Astaxanthin is a red pigment found in different types of algae and phytoplankton. It is astaxanthin that gives salmon and trout their reddish color. It is considered to be one of the most potent natural antioxidants, almost 50 times stronger than beta-carotenes found in fruits and vegetables and 65 times better as an anti-oxidant than vitamin C. Krill oil is composed of 40% phospholipids, 30% EPA and DHA, astaxanthin, vitamin A, vitamin C, various other fatty acids, and flavanoids (anti-oxidant compounds) Human studies indicate krill oil is powerful at decreasing inflammation throughout the body, especially in the brain. It reduces C-reactive protein, a marker for heart disease. Tests indicate it has a powerful anti-inflammatory remedy for rheumatoid as well as osteoarthritis.

Lobster Review
Seafood Watch Seafood Report American lobster Homarus americanus (Image © Monterey Bay Aquarium) Northeast Region Final Report February 2, 2006 Matthew Elliott Independent Consultant Monterey Bay Aquarium American Lobster About Seafood Watch® and the Seafood Reports Monterey Bay Aquarium’s Seafood Watch® program evaluates the ecological sustainability of wild-caught and farmed seafood commonly found in the United States marketplace. Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from the Internet (seafoodwatch.org) or obtained from the Seafood Watch® program by emailing [email protected]. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices,” “Good Alternatives,” or “Avoid.” The detailed evaluation methodology is available upon request. In producing the Seafood Reports, Seafood Watch® seeks out research published in academic, peer-reviewed journals whenever possible. Other sources of information include government technical publications, fishery management plans and supporting documents, and other scientific reviews of ecological sustainability. Seafood Watch® Fisheries Research Analysts also communicate regularly with ecologists, fisheries and aquaculture scientists, and members of industry and conservation organizations when evaluating fisheries and aquaculture practices.

Heart Health Through Whole Foods
Heart Health Through Whole Foods Certain whole foods in a diet can ultimately provide heart-healthy benefits. The right foods consumed in the right amounts can help lower cholesterol and/or triglycerides. They may also help to reduce risk for heart disease. Even though the benefits of whole foods may be known, too often individuals turn to over-the-counter supplements instead. It is important to discuss all supplements prior to ingestion with your physician. Individuals may not realize that taking some supplements with certain medications may be harmful or that taking too much of a good thing can be bad. The purpose of this session is to educate how to obtain certain nutrients through whole foods rather then through supplements. It must be noted that some individuals may still need supplements in addition to diet. Once again this should be guided by a physician.

Effect of Protein Hydrolysate from Antarctic Krill on the State of Water and Denatur- Ation of Lizard Fish Myofibrils During Frozen Storage
Food Sci. Technol. Res., 8 (3), 200–206, 2002 Effect of Protein Hydrolysate from Antarctic Krill on the State of Water and Denatur- ation of Lizard Fish Myofibrils during Frozen Storage Nong ZHANG1, Yasumitsu YAMASHITA1 and Yukinori NOZAKI2* 1Graduate School of Marine Science and Engineering, and 2Faculty of Fisheries, Nagasaki University, Bunkyo, Nagasaki 852-8521, Japan Received May 24, 2001; Accepted April 17, 2002 Protein hydrolysates were prepared from Antarctic krill and two types of shrimp by enzymatic treatment using protease. Hydrolysates prepared from the krill were added to lizard fish myofibrils, and changes in the amount of unfrozen water in myofibrils during freezing were analyzed by differential scanning calorimetry. Ca-ATPase activity of myofibrils was measured concurrently and the results were compared with those using hydrolysates from shrimp. The amount of unfrozen water increased after addition of the hydrolysates and decreased moderately during frozen storage. When hydrolysates were not added to myofibrils, the amount of water rapidly decreased during frozen stor- age. The decrease in ATPase activity during frozen storage followed that of unfrozen water, indicating a close correla- tion between ATPase activity and the amount of unfrozen water. These results suggest that the denaturation of myofibrils may be suppressed by the addition of hydrolysates, since the hydrolysates appeared to increase the amount of unfrozen water.

Received: 26 September 2018; Accepted: 26 October 2018; Published: 29 October 2018 Abstract: We examined the food preference of Chinese mitten crabs, Eriocheir sinensis (H. Milne Edwards, 1853), under food shortage, habitat choice in the presence of predators, and cannibalistic behavior by comparing their response to the popular culture plant Elodea nuttallii and the structurally more complex Myriophyllum verticillatum L. in a series of mesocosm experiments. Mitten crabs were found to consume and thus reduce the biomass of Elodea, whereas no negative impact on Myriophyllum biomass was recorded. In the absence of adult crabs, juveniles preferred to settle in Elodea habitats (appearance frequency among the plants: 64.2 ± 5.9%) but selected for Myriophyllum instead when adult crabs were present (appearance frequency among the plants: 59.5 ± 4.9%). The mortality rate of mitten crabs in the absence of plant shelter was higher under food shortage, primarily due to cannibalism.
