The opening chapter describes the characteristics, challenges and opportunities pertaining to the Strait of Hormuz and reviews the present and future conditions of the marine environment in the region. Next, the authors analyze phytoplankton chlorophyll-a data obtained on 27 oceanographic cruises in the southern Gulf of Mexico between 1979 and 2000. Four cruises were selected to report variations of chlorophyll-a associated with hydrographic conditions (temperature and salinity) in surface waters, one in April 1983 and three in different seasons in 1987. Data on the abundances of >105 cells/L of the non-toxic benthic-planktonic widely distributed ubiquitous pennate diatom Cylindrotheca closterium as a causative agent of harmful algal blooms in the coastal waters of the northern Yucatan Peninsula, with an emphasis on four marinas, are presented in the following chapter. Following this, studies are presented wherein it is shown that substrate type, species diversity, stem and root density, predator, seasons, and mate display activity affect the zonal and spatial distribution as well as the diameter of a burrow in semi-terrestrial crabs. The authors go on to highlight the applications of the most active compounds present in marine macroalgae known as polyphenols, as well as their isolation using green extraction methods. Their bioactive properties are reviewed and their potential for health improvement is evaluated. The penultimate chapter focuses on tributyltin, a toxic compound with broad-spectrum activity toward diverse marine species, and how it affects marine environments. The closing chapter examines the several molecular methods which have been evaluated for species identification, phylogenetic analyses, and determining the population structure of Thunnus.

This is a book that has been divided into 9 chapters, including information on the recovery of highly valuable compounds for microalgae. The authors of this volume discuss seaweed as a renewable and globally available feedstock with potential applications in the food and feed industries, as well as the agricultural, chemical, or pharmaceutical fields. The chapters include discussions on a wide range of topics including an overview of seaweed by-products, Algae and microalgae biorefineries, the potential use of seaweed by-products in various products and materials, colour stability, and pigment contents of powdered laver (Pyropia yezoensis). The text also includes the interactions of the algae Sargassum muticum with metals as a starting point for the valorisation of invasive seaweed species, as well as new insights into the nutrition and functionality of seaweed. Microalgae biomass as an ingredient to design added value in food products, as well as seaweed biomass for bioremediation or Ethanol creation are additional topics.

In today's environmental and economic climate, it is important for businesses to drive development towards sustainable and zero-waste industries, responsibly leveraging renewable low-cost inputs to generate high-value outputs for the global market. Marine macroalgae presents modern businesses with opportunities for the development of a new and vibrant industry sector that largely fulfills these requirements. Harnessing Marine Macroalgae for Industrial Purposes in an Australian Context: Emerging Research and Opportunities provides emerging perspectives on the theoretical and practical aspects of developing a new business sector within the bio-marine industry. Featuring coverage on a broad range of topics such as competitive advantage, food industry, and production systems, this publication is ideally designed for environmental researchers, business students, engineers, and academicians seeking current research on the economics, regulation, and policy in supporting the development of the macroalgal industry sector in the global market.
