Abstract:
The increasing market demand for Glyptocidaris crenularis shapes its great potential for aquaculture. Temperature is an important
factor affecting gonad production and quality of sea urchins. Therefore, it is essential and valuable to carry out an evaluation of the temperature
effects on gonad production and quality in G. crenularis before potential aquaculture. Here, we investigated the long-term effects of
temperature on gonad production, colour and flavour in G.
crenularis . There was no significant difference of test
diameter, height and body weight between the sea urchins in high (16–23°C) and low (12–16°C) temperatures ( P 〉 0.05). Glyptocidaris crenularis showed significantly higher
gonad production and index in high temperature and in low temperature ( P 〈 0.05). L *, a *, b * readings were slightly higher in the low temperature
groups, although no significant difference was found ( P 〉 0.05). Subjective colour and flavour ratings found
that G. crenularis in the low temperature group showed
significantly better colour ( P = 0.003) and flavour
( P 〈 0.001) than those in the high temperature group.
The present study provides valuable and insightful information into the establishing G. crenularis aquaculture.
