“…A representative example is that of the historical red coral banks of the Gulf of Naples, largely unrecovered nowadays (Bavestrello et al 2014a). The Mediterranean red coral shows a slow resilience due to the limited larval diffusion potential (Costantini et al 2007;Ledoux et al 2010), high post-settlement mortality (Cerrano et al 2001), low growth rates and reproductive output that increases with size (Garrabou & Harmelin 2002;Santangelo et al 2004Santangelo et al , 2012Bramanti et al 2007Bramanti et al , 2014Gallmetzer et al 2010;Linares et al 2010;Priori et al 2013). Moreover, the overexploitation has certainly favoured a higher genetic separation within and among coral populations, leading to a decreased genetic diversity (Costantini et al 2007).…”

“…In particular, the Calafuria population has been extensively studied in terms of demography, recruitment, early growth rates and genetics Santangelo & Abbiati 2001;Santangelo et al 2007Santangelo et al , 2012. Similarly, the distribution, size/age ratio, and sexual structure of a population living between 60 and 90 m NW off Elba Island, subject to historical and recent harvesting, have been also analysed (Priori et al 2013.…”

The aim of this paper is to supply an overview of all historical and recent knowledge on landings, fishing and geographic distribution of the red coral banks along the Italian coasts in order to make a contribution to the conservation and future management of this resource. Along the Italian coasts, the banks have been exploited for millennia, using non-selective trawling gear that was banned in Europe in 1994. Today, harvesting is allowed only by scuba divers and regulated by specific laws. We examined 153 years of history of coral fishing in Italy, from Unification (1861) to 2014. Data about the coralline fleets and the amount of coral landings were recorded for the considered span of time. From a quantitative point of view, the coral fishing in Italy in the last 150 years has been dominated by the sub-fossil coral reservoirs from the Sciacca Banks (Sicily Channel), where an extraordinary amount of 18,000 tons was collected in 34 years (1875-1888 and 1893-1914). This amount represents about 90% of all red coral harvested along the Italian coast in the last 150 years. Excluding this period, the average annual yield was initially around 100 tons, decreasing to 28 tons 100 years later, therefore demonstrating a severe overexploitation of the resource. The great part of the deep red coral banks was abandoned because harvesting was no longer profitable. Nevertheless, quantitative data suggest that red coral banks, even though overexploited, are still widespread along Italian coasts, mainly in shallow waters. These banks show a remarkable persistence although with a generalised shift towards smaller colony sizes and higher density. The time span necessary in recovering the pristine structure, following the end of the fishing activities, appears very long and the populations of several areas might be unable to re-colonise the old and overexploited banks.

“…From the historical perspective, precious corals are well known since the antiquity for their beauty and valued for the mysterious powers often attributed to their skeleton, especially the bright red ones . Far from being close to extinction, a decline in shallow‐water populations of this widespread taxon has been anyway observed and some concerns about its management have been raised and debated . Precious corals have been recently proposed for inclusion in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES 2013) regulating the international trade of endangered species.…”

Precious coral non‐destructive characterization by Raman and XRF spectroscopy

et al. 2016

Precious corals are some of the most valuable living marine resources, growing and commercially exploited only in limited areas of the world, namely the Mediterranean Sea and the Northern Pacific Ocean. Their skeleton is formed by calcium carbonate crystallized in the form of calcite whereas their color is because of the presence of partially demethylated polyene pigments. Recently, Pacific corals have been included in the appendix II of CITES list, while Mediterranean corals are still excluded. Different Corallium species of Corallidae family (e.g. Corallium rubrum, Corallium elatius and Corallium secundum) collected from different locations of the Mediterranean Sea and the Pacific Ocean were analyzed by Raman spectroscopy for the characterization of the reddish pigment and by X‐ray fluorescence (XRF) for the determination of the chemical composition of their skeletons, in order to obtain molecular and elemental data with two relatively easy and non‐destructive techniques, which can be used quite steadily for authentication purposes. Raman analysis demonstrated the presence of specific vibrational bands useful to identify the colored pigments as a mixture involving methylated and demethylated polyenes such as carotenoids and parrodienes, characterized by the presence of ―CH3 groups along the polyene chain. The ratio between the Raman signal and fluorescence background was found to vary as a function of the macroscopic color of the coral, but Raman analyses resulted inadequate for distinguishing between corals having similar color but different origins. On the other side, XRF data provided reliable information for an appropriate separation between Pacific and Mediterranean corals at the elemental level. The results of this study will be of great relevance for the authentication and identification of the origin of corals in trade market by means of completely non‐destructive techniques.

“…For key species (ecosystem functioning), the population size structure and the pyramid model have been used as cost-effective indicators of population health (Minchinton & Scheibling 1991, Kipson et al 2014.

Abstract.-Megabalanus peninsularis is a key species in the rocky shore, particularly in Malpelo Island in the Eastern Tropical Pacific (ETP) where it dominates the mesolittoral zone and the infralittoral fringe. The size structure of M. peninsularis was determined to infer the population state (pyramid model) by measuring the basal diameter of individuals (n= 837) around the oceanic island. The species population distribution followed a bimodal pattern (class I-II and VII). The pyramid expansive model, with a relatively higher number of juveniles than adults suggests that the population is growing.
