“…Growth zones or age markers were then clearly visible in S. mirabilis. In regular sea urchins, age is also commonly determined by microscopic examination of a thin section of charred skeletal plate mounted on a slide under transmitted light (Heatfield 1971, Yoo et al 1982, Chung & Natsukari 1995, Gebauer & Moreno 1995, Hong & Chung 1998, Sellem et al 2000, Sano et al 2001. From this section a series of light and dark bands can be identified under reflected light, and the bands are used for age determination as well as for revealing patterns of skeletal growth (Birkeland & Chia 1971, Pearse & Pearse 1975, Brykov & Parasyna 1978, Lane & Lawrence 1982, Duineveld & Jenness 1984.…”

“…In the Mediterranean Sea, growth peaks during spring, when the water temperature is between 12 and 18°C, while sporadically occurs in autumn and is practically absent in winter [14][15][16][17]. As a result of these premises, it can be estimated that urchins of 2 cm in diameter are around 2 years old and it takes approximately 4-5 years for them to reach 4 cm in diameter [12,16,[18][19][20][21].…”

Several approaches have been tested to respond to the depletion of wild stocks, from the production of seeds to the setting up of closed echinoculture systems, starting with fertilization of eggs with the consequent development to adult sea urchins. Hence, in the last years, our research group has focused on the assessment of a feasible and sustainable strategy aimed to ensure a rapid and effective gonadal growth of healthy gametes in recirculating aquaculture system (RAS) to employ in ecotoxicological application. In order to compare the health of obtained gametes with wild populations, the effectiveness of diets was evaluated with different biological parameters, such as fertilization and embryo-development test, and with histological analysis of gonads to appraise the stage of maturation. Moreover, the information regarding different breeding conditions of adults and genetic variability should be combined with the analysis of larval settlement and its requirements, demonstrating the importance of these parameters for the possible closure of the echinoculture cycle in RAS. Results achieved so far in terms of gonadal development and health of gametes have provided evidence of success in overcoming natural gaps between reproductive events in natural populations and an efficient and standardize breeding condition in RAS.

Paracentrotus lividus gonads represent a valued gourmet delicacy, particularly appreciated in Europe and in Japan. Their commercial value is generally associated to their size, freshness, colour and texture. Diet, gametogenesis and environmental conditions have a marked influence, promoting the indispensable mechanisms of synthesis, selective storage and mobilization of the bioactive compounds, as lipids, proteins and carbohydrates of gonads in order to obtain nutrients. The objective of this work is to compare the morphological and biochemical profiles of reproductive life cycle of the gonads of adult P. lividus in its marine natural environment and adult captured sea urchins breeding into a fish aquaculture system. The reproductive cycle of male and female wild and breeding P. lividus was characterized during 1 year by analysing variations of the gonadal content of lipids, proteins and carbohydrates of animals captured at four different locations of the south-western coast of Salento, Italy, with the animals grown in a fish farm and fed with four different types of diet. The gonadal and repletion indexes were determined before the specimen dissection for evaluation of sex, development stages and physiological aspects. Gonads were processed for histological and biochemical analysis. The gonadal content of lipids, proteins and carbohydrates was performed by the gas chromatography-mass spectrometry (GC-MS) and by spectrometry, respectively.
