Response of Hard-Bottom Macro-Zoobenthos to the Transition of a Mediterranean Mariculture Fish Plant (Mar Grande of Taranto, Ionian Sea) into an Integrated Multi-Trophic Aquaculture (IMTA) System

Journal of Marine Science and Engineering, Journal Year: 2025, Volume and Issue: 13(1), P. 143 - 143

This study investigates the effects on hard-bottom macro-zoobenthic communities of converting a mariculture plant into an Integrated Multi-Trophic Aquaculture (IMTA) system. was conducted from 2018 to 2021 in semi-enclosed Mar Grande basin Taranto (northern Ionian Sea), facility located 600 m off coastline, with production capacity 100 tons per year seabass (Dicentrarchus labrax) and seabream (Sparus aurata). The results seasonal sampling performed treatment site, where bioremediators (filter-feeding invertebrates such as sponges, polychaetes, mussels, macroalgae) were deployed, control site without compared. Before IMTA installation, hard substrates under cages sparsely inhabited, significant sediment coverage. By 2021, exhibited revitalized more diverse communities, species richness increasing 83 taxa 104 taxa, including notable growth annelids, mollusks, bryozoans. In contrast, showed no substantial changes biodiversity over same period. Biodiversity indices, Shannon Margalef improved significantly at particularly during summer months, highlighting resilient balanced benthic environment. Taxonomic distinctness (delta+) multivariate analyses (PERMANOVA, PCO) confirmed spatial temporal shifts community structure driven by implementation. SIMPER analysis identified key contributing these changes, which played pivotal role structuring community. emergence filter feeders, predators, omnivores suggests enhanced nutrient cycling trophic complexity, while decline opportunistic further supports environmental conditions. These findings demonstrate potential promote recovery sustainable practices, also offering comprehensive understanding its positive dynamics.

A survey of current trends and suggested future directions in coral transplantation for reef restoration

PLoS ONE, Journal Year: 2021, Volume and Issue: 16(5), P. e0249966 - e0249966

Published: May 3, 2021

Coral transplantation has been used in reef restoration for several decades, but information on the type of projects, their scope, scale, and success is mostly limited to published scientific studies technical reports. Many practitioners do not have capacity share progress peer-reviewed literature, yet likely a wealth how improve efficiency efforts. In order incorporate non-published data coral projects gain an overview general features these we conducted initial systematic online survey run by various practitioners. Surveyed ( n = 50) covered most tropical belt ranged size from few hundred transplanted corals >5000 transplants. The frequent source fragments were already broken some previous impact (“corals opportunity”; 58% projects), followed stored different types aquaculture systems (42% projects). use sexual reproduction was very limited.

Aquaculture and Restoration: Perspectives from Mediterranean Sea Experiences

Water, Journal Year: 2021, Volume and Issue: 13(7), P. 991 - 991

Published: April 4, 2021

In this paper, the different possibilities and innovations related to sustainable aquaculture in Mediterranean area are discussed, while maricultural methods, role of Integrated Multi-Trophic Aquaculture (IMTA) supporting exploitation ocean’s resources, also reviewed. IMTA, mariculture general, when carefully planned, can be suitable for environmental restoration conservation purposes. Aquaculture, especially mariculture, is a sector that progressively increasing parallel with increase human needs; however, several problems still affect its development, mainly relation choice sites, fodder production, impact on surrounding environment. A current challenge requires solutions implementation IMTA. Unfortunately, some criticisms approach, mostly concerning commercialization new products such as invertebrates seaweeds, notwithstanding their environmentally friendly character. Regarding location site, plans currently displaced from inshore offshore, aim reducing competition space other activities carried out within coastal waters. Moreover, open water, waste loading does not appear problem, but high-energy waters maintenance costs. Some suggestions given developing area, where IMTA infancy scarce nutrients characterize offshore farming both filter feeder macroalgae. From perspective coupling activity ecology, practices suggested review concern creating artificially controlled gardens, well mussel coupled artificial reefs, hypothesizing possibility use eutrophized areas.

Runaway Climate Across the Wider Caribbean and Eastern Tropical Pacific in the Anthropocene: Threats to Coral Reef Conservation, Restoration, and Social–Ecological Resilience

Atmosphere, Journal Year: 2025, Volume and Issue: 16(5), P. 575 - 575

Published: May 11, 2025

Marine heatwaves (MHWs) are increasingly affecting tropical seas, causing mass coral bleaching and mortality in the wider Caribbean (WC) eastern Pacific (ETP). This leads to significant loss, reduced biodiversity, impaired ecological functions. Climate models forecast a troubling future for Latin American reefs, but downscaled projections WC ETP remain limited. Understanding regional temperature thresholds that threaten reef futures restoration efforts is critical. Our goals included analyzing historical trends July–August–September–October (JASO) anomalies exploring at subregional country levels. From 1940 2023, JASO air ocean showed increases. Projections indicate even under optimistic scenario 4.5, temperatures may exceed +1.5 °C threshold beyond pre-industrial levels by 2040s +1.0 annual maximums 2030s, resulting severe mortality. Business-as-usual 8.5 suggests conditions will become intolerable conservation with decadal warming largely surpassing rates, unbearable corals. The immediate development of local adaptive plans, along climate change adaptation mitigation strategies, essential provide time scenarios materialize.
