“…It is possible that this species is feeding on different prey type, probably including macroalgae and invertebrate species. Little is known about the diet of this species, however Hernández-Almaraz et al (2022 reported similar d 15 N values (from 15.0 ± 0.2‰ to 17.5 in E. thouarsii and from 11.6 ± 1.2 to 16.9 ± 0.5‰ in T. depressus) for E. thouarsii in LAP. For stomach content analysis it is known that E. thouarsii consumes certain invertebrates, seagrass, and calcareous algae (Hernández-Almaraz et al, 2022; Lawrence and Agatsuma, 2013), but brown and red macroalgae are the main food, principally macroalgae of the genera Sargassum, Gracilaria, and Laurencia (Hernández-Almaraz et al 2016).…”

T. depressus is most common in very shallow waters, and occur on variety of habitats, including seagrass and algal beds, rock, coral reef ats, and sand with rubble (Lawrence and Agatsuma 2013).…”

Sea urchin species are ecologically important in the Gulf of California and are becoming popular as a local fishery due their commercial value. The most abundant species are Echinometra vanbrunti, Eucidaris thouarsii, and Tripneustes depressus. The aim of this study was to evaluated cadmium, lead, copper, zinc, and iron concentrations as well as stable isotope values in these sea urchin species in mining area of Santa Rosalia (STR). Metal concentrations were analyzed by atomic absorption spectrophotometry and stable nitrogen and carbon isotopes were estimated using mass spectrophotometry. Highest values of Fe (108.8 mg Kg−1), was found in E. vanbrunti, while highest values of Pb (15.4 mg Kg−1), Cu (14.5 mg Kg−1), and Zn (347.7 mg Kg−1) were found in E. thouarsii; and highest values of Cd (10.8 mg Kg−1) was found in T. depressus. The main ecological risk of trace metal pollution in STR may be caused by Cd and Pb. d15N values were higher in E. thouarsii and d13C in T. depressus, and E. thouarsii have the highest trophic position. There is not relationship between size and metal concentrations, but a positive relation exists between size and isotopic values in T. depressus. The three species showed different bioaccumulation pattern for the metals analyzed. Additionally, collection site and season play an important role in the metal concentration variability. Given that these species are consumed by humans, some risk of trace metals toxicity could be expected due to the accumulation patterns and characteristics of the sites studied.

“…In this study, T. gratilla was selected as the research subject because of its excellent characteristics, such as full gonads [24], closed life cycle [25], high growth rate [26], and high market value [24]. Recent studies on T. gratilla have focused on the effects of different baits on the growth and reproduction of sea urchins [27][28][29], the feeding preferences of sea urchins for algae [24,30], and the population growth patterns and distribution of sea urchins [31,32]. T. gratitlla is a benthic organism that lives on a shallow sandy seabed where short-wavelength blue and green light is more widely distributed and long-wavelength red light is more severely attenuated.…”

To study the effects of light color on sea urchin (Tripneustes gratilla), blue light (B, λ450nm), yellow light (Y, λ585–590nm), red light (R, λ640nm), green light (G, λ510nm), white light (W, λ400–780nm), and darkness (H) groups were established in a recirculating seawater aquaculture system. Six different LED light color treatment groups with a photoperiod of 12 L:12 D were tested for 30 days to investigate the effects of different light colors on the feeding, growth, and enzyme activities of T. gratilla (142.45 ± 4.36 g). We found that using different LED light colors caused significantly different impacts on the feeding, growth, and enzyme activity of T. gratilla. Notably, the sea urchins in group B exhibited better growth, with a weight gain rate of 39.26%, while those in group R demonstrated poorer growth, with a weight gain rate of only 26%. The feeding status differed significantly (p < 0.05) between groups B and R, with group B consuming the highest daily intake (6.03 ± 1.69 g) and group R consuming the lowest (4.54 ± 1.26 g). Throughout the three phases, there was no significant change in the viability of the α-amylase (p > 0.05). Conversely, the pepsin viability significantly increased (p < 0.05) in group B. The lipase viability consistently remained at the lowest level, with no notable differences between group W and group B. In group R, both the α-amylase and pepsin viabilities remained lower, whereas the lipase viability was noticeably greater in each phase than in group B (p < 0.05). Among the antioxidant enzymes, group R exhibited a trend of initial increase followed by decreases in catalase, superoxide dismutase, and glutathione peroxidase activities, particularly during the third stage (15–30 days), during which a significant decrease in antioxidant enzyme activity was observed (p < 0.05). Taken together, these findings suggest that blue light positively affects the growth, feeding, digestion, and antioxidant capacity of T. gratilla in comparison with those in other light environments, whereas red light had an inhibitory effect. Furthermore, T. gratilla is a benthic organism that lives on shallow sandy sea beds. Thus, as short wavelengths of blue and green light are more widely distributed on the seafloor, and long wavelengths of red light are more severely attenuated on the seafloor, shorter wavelengths of light promote the growth of bait organisms of sea urchins, which provide better habitats for T. gratilla.
