All Rights Reserved. .org Foreword The oceans have a profound effect on all of us. We also have a profound effect on the health of our oceans and, unfortunately, it is often not positive. As our understanding of the complex systems that support ocean life has improved, we are realizing just how much of an impact we are having on the world beneath the water’s surface. Despite these increasing challenges, our oceans are an amazing treasure of biodiversity, healthy food, and awe! Given the right tools and education, everyone has an opportunity to engage in marine conservation and help protect the global treasures of the sea. By learning (and teach- ing) about the issues affecting the health of our oceans, and by making informed choices, you become part of a larger community of ocean and sustainable seafood ambassadors leading by example: together we can maintain healthy and abundant oceans for future generations.

    DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Graduate School of Biosphere Science Hiroshima University September 2014 DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Department of environmental Dynamics and Management Graduate School of Biosphere Science Hiroshima University September 2014 Abstract The moon jellyfish Aurelia aurita s.l. is the most common scyphozoan jellyfish in the coastal waters around the world, and the mass occurrences of this species have been reported from various regions. In recent decades, A. aurita blooms have become increasingly prominent in East Asian seas, causing serious problems to human sectors such as fisheries and coastal power plant operations. Therefore, it is important to identify causes for the enhancement of A. aurita populations to forecast likely outbreaks prior to the season of medusa blooms. In the population dynamics of scyphozoan jellyfish, the following two factors are important to determine the size of adult (medusa) population: (1) the abundance of benthic polyps, which reproduce asexually and undergo seasonal strobilation to release planktonic ephyrae, and (2) the mortality of ephyrae before recruitment to the medusa stage. Although much knowledge has been accumulated about physio-ecology of the polyp stage by previous studies, only few studies have been conducted for the ephyra stage. The success for survival through larval stage is basically affected by two factors, viz. food availability and predation.

Peatman, Assistant Professor, Fisheries and Allied Aquacultures Joseph C. Newton Associate professor, College of Veterinary Medicine Abstract Investigative studies were conducted on the relative effectiveness between carp pituitary extract (CPE), luteinizing hormone releasing hormone analog (LHRHa) injections and LHRHa implants for producing hybrid catfish embryos. Data from the past 15 years, which included, 25 on CPE, 20 on LHRHa injections, and 20 for LHRHa implants, respectively, were evaluated. LHRHa administered as an injection or implant produced more (P<0.001) fry/kg than CPE. Mean fry/kg female body weight (all females) produced was 948 for, CPE 2,483 LHRHa injections and 2,765 for LHRHa. There was not a significant difference in fry/kg between the two LHRHa treatments. The coefficient of variance indicated more consistent results for CPE (CV=37.5), and LHRHa implants (CV= 35.9) than LHRHA injections (CV= 49.9). The second study investigated the effectiveness of OVA-EAZE a Luteinizing Hormone Releasing Hormone analog (LHRHa).

    DETERMINATION OF ALUMINUM CONTENT IN FOOD PRODUCTS AND TEXTURE PROFILE OF JELLYFISH PRODUCTS by CHAO XU (Under the Direction of Yao-wen Huang) ABSTRACT This study analyzed texture properties and mineral profiles of jellyfish products, which can provide valuable information for utilizing jellyfish as a potential food resource, as well as developing appropriate strategies to control the product quality. Desalting cured jellyfish in water is a critical step to create jellyfish a desirable texture. Inorganic elements in processed jellyfish were also under investigation. Fresh jellyfish are processed with mixture of salt and alum, and then the cured jellyfish are desalted in water before consumption. Very little is known about the inorganic constituents of jellyfish. In this study desalted jellyfish were examined for 7 elements, including Al, Ca, K, Mg, Na, Fe, and Zn, using inductively coupled plasma optical emission spectrometry. High amount of aluminum was found in cannonball jellyfish samples. High performance liquid chromatography (HPLC) with spectrophotometric detection using quercetin is developed to determine aluminum content.

Ecology Action Centre, and Living Oceans Society. 2 Canada’s In-depth Guide to Sustainable Seafood WHAT IS SUSTAINABLE SEAFOOD? Sustainable seafood is fish or shellfish caught or farmed in a manner that can be sustained over the long-term without compromising the health of marine ecosystems. Unfortunately, the effects of unsustainable fishing and aquaculture practices are already obvious right here in Canada and worldwide. But, it’s not too late. Everyone can make a difference by learning about sustainable seafood and making more ocean-friendly choices. DETERMINING SEAFOOD SUSTAINABILITY SeaChoice works with the Monterey Bay Aquarium to provide science-based sustainability rankings for the majority of seafood sold in Canada; both farmed and wild. As practices and products change, SeaChoice adds new listings and updates. Seafood options found on the SeaChoice “Best Choice”, or green list, are the most sustainable based on ecological impacts (social equality and climate change are not considered at this time). Seafood on the yellow “Some Concerns” list should be eaten when a best choice is not available. Options ranked “Avoid” on the red list have serious conservation concerns, and should always be avoided.
