“…Nevertheless, after a peak in 1995 of more than 116 367 metric tonnes of sea urchins captured worldwide (Andrew et al . ; Sun & Chiang ; Stefánsson et al . ), catches dropped to approximately 76 242 metric tons in 2014 (Stefánsson et al .…”

“…The Japanese market represents 90% of the global market, importing 80% of their internal consumption (Sun & Chiang ), and for this reason, the preferences of Japanese consumer set the quality standards for the sea urchin roe. High‐quality roe usually stands for large gonads golden orange to yellow with a distinct, sweet ocean taste commercially identified as uni (Sun & Chiang ). To achieve this high‐quality standard for roe, studies conducted to date have evaluated different species and manipulated a diversity of factors, ranging between environmental factors (e.g.…”

Sea urchin roe is highly appreciated worldwide as a gourmet product comparable to caviar. Research in echinoculture mainly focus on the production of high-quality roe which stands for large golden orange to yellow gonads with a distinct, sweet ocean taste known as uni. The scientific approaches to manipulate roe quality are diverse in terms of targeted species and manipulated factors as nutrition, environmental and husbandry conditions. In this study, a meta-analysis approach was applied to systematically review the research conducted between 2000 and 2017 aiming to enhance the sea urchin roe quality. The 48 studies selected and analysed here show that those targeting the growth of gonads were successful, independently of the selected species, the rearing system adopted, or the diet or nutrient tested. In contrast, most trials focusing on colour manipulation resulted in roe colour similar to the control group (sea urchins fed with algae). Only six studies aiming to enhance roe taste were selected but described inconclusive results. In conclusion, while the production of large gonads seems easily achievable, the enhancement of its colour and taste is still a challenge.

“…The roe (gonad) of sea urchins have been utilized as seafood products in many parts of the world, particularly Asia and Europe (Baiao et al, 2019;Kato, 1972;Salvo et al, 2016;Taylor et al 2017). Thereby, Sea urchin gonads have highly valued commercially (Lawrence, 2007;Brown and Eddy, 2015;Sun & Chiang, 2015). As a consequence, demand on sea urchin gonads is rapidly increasing globally (Brown andEddy 2015, Mos &Dworjanin, 2019).…”

Sea urchin Tripneustes gratilla is one of an economic important fisheries resources product for localities at Wakatobi archipelago. High demands for sea urchin gonad have intensified high fishing activity. We hypothesize that sea urchins at Wakatobi have overfished. To answer that hypothesizes; we measure the density and its test diameter size at two different sites. They are Pulau Tomia (inhabited area) and Pulau Sawa (uninhabited area and very distant from the localities). The results show that sea urchin density and its test diameter is significantly different. The densities (mean ± SE) Tripneustes gratilla at Pulau Sawa and Pulau Tomia are 10 ± 0.6 (ind./ m 2 ) and 2.7 ± 0.9 ind./m 2 , respectively. Moreover, the test diameter at Pulau Sawa and Pulau Tomia are 69.7 ± 2.1 mm (mean ± SE), and 58.5 ± 1.7 mm (mean ± SE), respectively. These results have indeed shown that overfishing has occurred. Therefore, sea urchin with test diameter 66-75 mm, 76-85 mm, and 86-95 mm have disappeared at Pulau Tomia. Our conclusion reveals that fishing of sea urchin Tripneustes gratilla at Pulau Tomia has overfished.
