AbstractOver the past 5 years, with the growth of fish production and the improvement of distribution channels, the global fish food demand has also grown; in such a context, natural stocks of Echinoderms have suffered a marked reduction in production. This scenario was exacerbated for Pararacentrotus lividus by the fact that this species was recognized worldwide among the most reliable as a bioindicator, and its gametes have been used for biological assays for monitoring marine pollution.

Importance of Gamete Quality in Ecotoxicological Application: Natural versus Bred Population in Paracentrotus lividus

Assessment of a feasible and sustain able strategy aimed to ensure a rapid and effective gonadal growth of healthy gametes in recirculating aquaculture system (RAS) to employ in ecotoxicological application and the importance of these parameters for the possible closure of the echinoculture cycle in RAS.

Can sea urchins benefit from an artificial diet? Physiological and histological assessment for echinoculture feasibility evaluation

The results presented in this study demonstrated the good feasibility of a low-cost and easy-to-standardize diet, such as that based on maize and spinach, in rearing vulnerable species such as P. lividus in RAS.

Experimental evaluation of the feeding rate, growth and fertility of the sea urchins Paracentrotus lividus

The daily feeding rate of the sea urchin P. lividus is defined to be useful for the definition of optimal diets for the production of mature broodstocks of an ecologically important marine model organism.

Can artificial diets be a feasible alternative for the gonadal growth and maturation of the sea urchin Paracentrotus lividus (Lamarck, 1816)?

Gonad color analyses confirmed a redder roe in females and also the suitability of C. maxima as a potential gonad color enhancer for P. lividus.

Roe enhancement of Paracentrotus lividus : Nutritional effects of fresh and formulated diets

Most sea urchins are typical plant feeders, but their trophic role is usually played as large and abundant macroherbivores, and their natural diets are quite complex and contain several items indispensable to complete the assortment of feeding principles ingested.



Echinoculture: rearing of Paracentrotus lividus in recirculating aquaculture system. Experimentations of artificial diets for sexual maturation

Two protocols to ensure the maintenance of mature organisms in Recirculating Aquaculture System (RAS) and to stimulate the maturation of mature Paracentrotus lividus, showing that Maize&Spinach diet gave the best results in terms of gonadosomatic index values (GI).

Year-round captive spawning performance of the sea urchin Paracentrotus lividus: Relevance for the use of its larvae as live feed

The results demonstrate the fea- sibility of producing larval P. lividus in that high numbers of fertilized eggs can be obtained year round and the main limitation of exploiting P. Lividus as planktonic feed seems to be the mortality of broodstock after injection with 1 ml KCl 0.5 M, which prevents reutilization.

Gametes and embryos of sea urchins (Paracentrotus lividus, Lmk., 1816) reared in confined conditions: their use in toxicity bioassays

The sea urchins reared under experimental conditions were characterised by faster gonad maturation than the field population, producing viable gametes and larvae whose biological response in toxicity bioassays was similar to that of field-reared specimens of P. lividus.

Phenotypic plasticity of Paracentrotus lividus (Echinodermata: Echinoidea) in a lagoonal environment

Results show that P. lividus is capable of changing its morphology in response to available food resources and demonstrate the high degree of plasticity of this species.

Effect of different formulated diets and rearing conditions on growth parameters in the sea urchin Paracentrotus lividus.

The growth mode! established with data obtained from the tank studies for individuals fed the mixed feed indicated that the growth of the sea urchin can be maximized by appropriate feeding.

Use of maize as a food source for sea urchins in a recirculating rearing system

Six diets were tested on the somatic growth and mortality of the sea urchin Paracentrotus lividus reared in a semi-closed system, finding the best growth rates were obtained with the mix maize plus P. palmata and the lowest conversion rates were obtain with the algal-based diets.

Nutrition of the sea urchin Paracentrotus lividus (Echinodermata: Echinoidea) fed different artificial food

A growth model based on the results shows that sea urchin growth can be explained by 4 factors: the quantity of food ingested; the amount of food absorbed; the size of the individuals; and the quantities of dry matter absorbed.

The Effect of Temperature on Production of Gonads by the Sea Urchin Strongylocentrotus franciscanus Fed Natural and Prepared Diets

Gonad production was not significantly different among the experimental treatments, indicating the prepared feed was nutritionally superior to the algal diet and an increase in catabolism at the higher temperature balanced the increase in food intake.
