“…Heavy metals are accumulated in benthic sediments, where they are incorporated into several biological and chemical cycles [50]. High concentrations of zinc, copper, or other metal elements are toxic to macrobenthic fauna and microalgae, which are crucial elements in the food-chain for natural fisheries production [51]. Moreover, the residues of medicines, antibiotics, and vaccines found in the effluent are common sources of anthropogenic chemical pollution derived from mariculture operations [52].…”

While marine aquaculture, or mariculture, has been growing rapidly and globally in recent decades, many environmental concerns remain to be fully addressed to achieve its long-term goal of sustainable development. This paper aims to provide a synthesized perspective on these issues by reviewing and discussing the characterization, transport, and current modelling and management tools associated with effluents released from mariculture sites. Specifically, we examined the effluent characteristics and behavior from source-to-sink, including the composition and load of effluent discharge, its transport and transformation processes in the water column and at the seabed, and its impacts on the pelagic and benthic environments. We then focused on management-related issues, including the setting of the regulatory mixing zone, the establishment of environmental standards, monitoring measures, and modelling techniques to depict the current state-of-the-art modes in a global context. Our study shows that while substantial progress has been made in understanding the nature of the mariculture effluent, as well as in monitoring and modelling its transport and fate, the regulatory framework still lags behind in many countries where the mariculture industry is relevant. This is particularly evident in the lack of consistent criteria for the definition of regulatory mixing zones and the associated environmental standards for water quality and benthic impacts. Besides, as new predictive models are emerging quickly, their proper evaluation and validation are imperative in view of their increasing application in regulatory practices. This review is intended to provide references for advancing regulatory management of mariculture effluents, as well as for promoting sustainable mariculture development.

“…The FI assesses the relative proportions of LBF against two categories of SBF, small heterotrophic species and opportunistic species (Hallock et al 2003). An FI = 4 implies 25% of the assemblage is LBF and FI > 4 indicates water quality that is suitable for coral growth; FI < 2 is unsuitable and between these two ranges the environment is marginal for coral growth (Hallock et al 2003) Low or declining FIs and/or densities of Foraminifera accompanied by changes in assemblages have been reported in reefs near urbanised and heavily populated sites around the world, including nearshore sites on the GBR and in Moreton Bay reflecting poor water quality (Schueth and Frank 2008;Uthicke and Nobes 2008;Fujita et al 2009;Narayan and Pandolfi 2010;Osawa et al 2010;Uthicke et al 2010;Fabricius et al 2012;Parsaian et al 2018). Changes in Foraminifera assemblages have also been demonstrated over short time periods.…”

Coral reefs are in decline worldwide due to local/regional (e.g., water quality and fishing) and global stressors (e.g., ocean warming and acidification). Palaeoecological studies help differentiate the effects of anthropogenic versus natural stressors, assist ecological interpretations of fluctuations in dynamic systems, and decipher the impact of future changes. Benthic Foraminifera are valuable proxies for monitoring coral reef condition. This project utilises Foraminifera preserved in a sediment core from the One Tree Reef (OTR) lagoon on the southern Great Barrier Reef (GBR) to quantify potential ecological changes associated with European colonisation (late 1700's) and industrialisation of Australia (1950's). Previous work focuses on foraminiferal assemblages from near shore reefs, but analysis of outer reef systems is lacking. OTR is located some 100 km from the mainland, removed from most local and regional stressors likely to drive changes in the foraminiferal assemblages.Richness, diversity and changes in foraminiferal assemblages over time using standard ecological indices and foraminifera specific metrics indicate that there has been no discernible trend or shift in OTR lagoon Foraminifera assemblages over the last four centuries. These Foraminifera assemblages suggest that the OTR lagoon may contain a living example of a pre-colonial GBR lagoon ecosystem.

“…The distribution of these microorganisms is conditioned by diverse physical-chemical parameters of the waters (salinity, dissolved oxygen, pH), as well as by the characteristics of the substrate where they live (granulometry, geochemistry) [1][2][3]. Its abundance and diversity can be altered by changes in the dynamics of the environment, erosion of the bottom or anthropic contamination, among other factors [4,5]. In southwestern Spain, several studies have analyzed the spatial distribution of benthic foraminifera in the different sedimentary environments of three estuaries (Guadiana, Piedras and Tinto-Odiel) [6][7][8].…”

Study AreaThe Guadalquivir river is the main fluvial stream of southwestern Spain (657 km). This river has a very irregular regime, with an annual average of 185 m 3 s -1 and a maximum of more than 1,000 m 3 s -1 [9,10]. These flows are partially controlled by several dams located upstream. The tidal regime is mesotidal and semidiurnal, with an average tidal range of 3.6 m [11]. The marine estuary of the Guadalquivir River is constituted by the
