Esso’s Long Island Point facility has been operating for more than 40 years beside Western Port in Victoria, and has discharged treated wastewater and storm water to the bay for most of these years. The 2001 State Environment Protection Policy Schedule F8 for Waters of Western Port is part of Victoria’s Environment Protection Authority’s (EPA) legal framework for licensing discharges to the waters of Victoria, and requires that discharges ‘cause no detrimental change in the environmental quality of the receiving waters, as determined by an environmental monitoring program’. As part of Esso’s ongoing commitment to continuous improvement, a major upgrade to the water treatment facility was completed to further improve the quality of waters discharged to Western Port. In conjunction with this upgrade, Esso is undertaking a study on the effects of the discharge on the environmental quality of Western Port. This peer-reviewed paper presents an example of the practical application of managing discharges to ensure that the stated environmental values of a receiving environment are protected. The environmental study focuses on four key aspects of marine-environment quality relevant to key Western Port ecosystem values in the vicinity of the facility’s effluent discharge, which are: ambient water quality; seagrass biomass; jetty pile epibiota; and, ecological risk through toxicity testing. The study demonstrates the implications of basing regulatory requirements on the quality of the site-specific environmental characteristics, rather than merely effluent quality and generalised water quality objectives. Furthermore, it validates the need for sound science to underpin regulatory limits and industry practices when operating in sensitive environments.

Collecting the spat of good quality and enough quantity, as the seeding material for commercial cultivation of scallop Mizuhopecten yessoensis Jay, 1857, is one of the main problems for aquaculture farms in Primorye. In the eastern Ussuri Bay, pacific mussel Mytilus trossulus Gould, 1850 is the dominant species which larvae settle on the systems designed for the scallop spat collecting. Its spat quantity in collectors exceeds the scallop spat number in 5-65 times, with the biomass in 3-140 times higher. The scallop spat survival dependence on abundance of the mussel spat is investigated but any correlation is not detected. However, general quality of the scallop spat in the farms in the Ussuri Bay is poor that could be a reason of its low survival on further stages of cultivation: mean size of the scallop spat here is close to the lower acceptable limit of the standard range (10-11 mm). Besides, food resources for the scallop spat could be limited in the years with high abundance of the mussel spat.

Holocene Foraminiferal fauna at the area of Phan Vinh island, Truong Sa archipelago is relatively abundant and diverse in both taxonomic composition and ecological characteristics. The initial research results have identified 69 species (excluding several ones unidentified) belonging to 42 genera, 25 families and 6 orders. Among them, the representatives of the genera of Calcarina, Amphistegina, Heterostegina, Elphidium, Amphisorus, Marginopora, Sorites, Parasorites, Peneroplis, Archaias, Siphonipheroides, Septotextularia are predominant. They characterized by the shallow, transparent and warm marine environments of the region of Truong Sa archipelago during Holocene. Some problems related to this fauna at the area of Phan Vinh island such as biodiversity of coral-reef ecosystems, stratigraphic and paleogeographical significances, and its role of reef - building are also mentioned in this article. In addition, for the modern Foraminifera in the world, today they are being used as ‘biomarkers’ (bioindicators) in assessing and monitoring environmental quality of coral reef ecosystems in particular and marine environment in general. In Vietnam, this method has not been applied, but in the future, this is one of the methods that should be concerned. In addition, in aquaculture the Foraminifera is also a source of nutrition that should not be ignored.

The bivalve mollusk, Anadara tuberculosa (Black Shell, in Spanish Concha Prieta), is found on America’s Pacific coast, where it is harvested for subsistence and commercial markets. This paper aims to diagnose the performance of the black shell’s value chain. We also identify several challenges that must be addressed to improve the sustainability of the black shell fishery in Ecuador. The applied methodology was quantitative and descriptive. Its design was non-experimental, field, cross-sectional and ex post facto. The investigation was carried out from January to October 2019 in the Jambelí archipelago, El Oro province, Ecuador. The study population consisted of 565 individuals, shellfish collectors, shellfish associations managers, traders, and restaurants from the A. tuberculosa production chain. The sample size was estimated at 222 informants. The type of sampling used was probabilistic, random, stratified, and with proportional allocation, with an effective participation rate of those selected of approximately 80%. The questionnaire was applied personally through the structured survey method, in writing, in the work area, and with their consent. The performance of the value chain was diagnosed in the dimensions of productivity, competitiveness, and quality of life, reaching a 75.1% index, a result that indicates that the value chain has a moderate to good performance level. The competitiveness dimension reached the highest performance, followed by productivity. Quality of life was the dimension with the lowest performance. The value chain can be improved if the following challenges are met: (1) Restoration of the mangrove ecosystem, (2) Promotion of low-intensity shellfish aquaculture, (3) Good sanitary management and purification, (4) Promotion of value-focused ventures, (5) Strengthening of organizations and agreements for the use and custody of mangroves, and (6) Strengthening of institutions that contribute to the advancement of these challenges.
