“…H. mammata was induced to spawn by thermal stimulation, being this methodology largely used in many other different tropical and temperate species, e.g. A. mauritiana, Athyonidium chilensis, A. mollis, Bohadschia marmorata, Holothuria atra, H. fuscogilva, H. tubulosa, H. scabra, and I. badionotus (Battaglene, Seymour, & Ramofafia, ; Battaglene, Seymour, Ramofafia, & Lane 2002; Dabbagh & Sedaghat, ; Eeckhaut, Lavitra, Léonet, Jangoux, & Rasolofonirina, ; Guisado, Carrasco, Díaz‐Guisado, Maltrain, & Rojas, ; Ivy & Giraspy, ; James, Rajapandian, Baskar, & Gopinathan, ; Kumara & Dissanayake, ; Kumara, Jayanatha, Pushpakumara, Bandara, & Dissanayake, ; Laxminarayana, ; Mercier, Battaglene, & Hamel, ; Morgan, ; Rakaj et al., ; Ramofafia, Byrne, & Battaglene 2003; Zacarías‐Soto et al., ). This method was also recently applied to induce the spawning to H. arguinensis (Domínguez‐Godino et al., ), species inhabiting with H. mammata the Portuguese waters.…”

Sea cucumber commercial fisheries in the North‐eastern Atlantic and Mediterranean Sea started in Turkey in the 1990s. Due to ineffective management practices, the sea cucumber resource was overexploited. Holothuria mammata is one of the sea cucumber species exploited from this geographical area, showing high potential for its aquaculture. This research was undertaken to develop the breeding, larval and juveniles rearing techniques for development of H. mammata aquaculture. Broodstocks collected from Ria Formosa (Faro, S Portugal) were successfully induced to spawn by thermal stimulation from July to October, yielding up to 6.95 million eggs/female. The eggs and larvae were reared and their development described. H. mammata showed the five typical larval stages of most aspidochirote holoturians. Juveniles stage was reached after 21 days post‐fertilization. This is the first work focused on the aquaculture biotechnology of H. mammata, however, further research is need to improve the survival of juveniles to ensure the future production of this species.

“…Sea cucumber juveniles of many species, regardless of the growing conditions, exhibit high size variability that increases over time (Battaglene et al, ; Guisado et al, ). Extensive variability was evident in weight and length in the current study, and a first estimation of the relation of these growth variables was made.…”

“…Despite Mexico establishing regulatory measures for the fishery of I. badionotus (Diario Oficial de la Federación., 2015;Hernandez-Betancourt et al, 2018), less than a decade after commercial fishery began, the wild populations show signs of overexploitation, indicating risk of collapse (Hernandez-Betancourt et al, 2018;Hernández-Flores, Cuevas-Jiménez, Poot-Salazar, Condal, & Espinoza-Méndez, 2018;Poot-Salazar, Hernandez Flores, & Ardisson, 2015;Purcell et al, 2011). This situation emphasizes the urgent need to develop aquaculture programs for the production of juveniles for commercial farming and to support programs for restoration of the wild populations (Asha & Muthiah, 2007;Guisado, Carrasco, Díaz-Guisado, Maltrain, & Rojas, 2012;Hu et al, 2010;Lovatelli et al, 2004;Rakaj et al, 2018).…”

“…Field studies of subadult individuals also indicate that growth in the field is seasonal, influenced by temperature and phytoplankton productivity (Hannah et al, 2012), which also varies depending on the sampling sites. Some data on growth and survival of early sea cucumber juveniles (<1 g and <1 cm) under controlled conditions have been reported for experimental laboratory-produced species, including Holothuria scabra (Jaeger, 1833;Battaglene, Seymour, & Ramofafia, 1999), Isostichopus fuscus (Ludwig, 1875;Hamel, Hidalgo, & Mercier, 2003), Holothuria spinifera (Théel, 1886;Asha & Muthiah, 2007), and Athyonidium chilensis (Semper, 1868;Guisado et al, 2012), and also for hatchery-produced species, such as Apostichopus japonicus (Selenka, 1867;Xie, Zhang, Liu, Zhang, & Yang, 2016) and Australostichopus mollis (Hutton, 1872;Zamora, Maxwell, & Jeffs, 2017). Generally, these studies indicate that, after settlement, there is high mortality and rapid growth, which decreases as individual size increases and varies according to the species and culture conditions.…”

Isostichopus badionotus is a new commercially important sea cucumber in the Caribbean that has rapidly shown signs of overexploitation. There is no information on the growth and survival rates for wild or hatchery‐produced early juveniles. Hatchery production and determination of juvenile growth rates are essential for future aquaculture efforts for this species. In this study, daily growth rate (GR), specific growth rate (SGR), weight gain (WG), survival rate (SR), and weight–length relation (WLR) were evaluated using small (0.01 g) and large (0.25 g) hatchery‐produced early juveniles under laboratory conditions. Growth was rapid compared to other cultured sea cucumber species; maximal values of SGR and WG were obtained for small juveniles (4.58%/day and 2,191%, respectively), while maximal GR and SR were obtained for large juveniles (0.29 mm/day and 99.17%, respectively). A wide range of sizes was evident at the end of each trial. The WLR of small and large juveniles fit with a negative allometric growth trend. This study highlights the potential production of I. badionotus as early juvenile stages withstand hatchery handling well and exhibit a high SR, reaching commonly released mean sizes (>0.7 g and 25 mm) after almost 3 months (120 days postfertilization).

Reproductive biology of the commercial sea cucumberAthyonidium chilensis(Holothuroidea: Dendrochirotida) in southern Chile

Reproductive aspects of the sea cucumber Athyonidium chilensis were studied over a year in Valdivia, Chile, through gonad index (GI) analysis, macro- and microscopic analysis of the gonads, fecundity and size at first sexual maturity estimations. We also explored the reliability of live size estimators for their use in fisheries. Athyonidium chilensis showed continuous gametogenesis and spawning individuals could be found throughout the year. However, spring was the main reproductive time, where an important GI decrease coincided with enhanced spawning activity evidenced through histology. GIs recovered in summer, and new signs of enhanced spawning activity were observed towards autumn (April 2008). GI peaks were observed in August 2007 and March 2008 for females (22.8 and 24.4% respectively) and September 2007 and March 2008 for males (31.9 and 25.9% respectively). Low mean GIs occurred in May and December 2007 for females (15.2 and 11.6% respectively) and May and October 2007 for males (12.7 and 14.1% respectively). Males reached sexual maturity at a smaller size than females (males: 21.2 g, females: 43.7 g eviscerated weight), and mature females showed a high mean absolute fecundity for a species with lecithotrophic larval development (6.31 × 105 ± 1.97 × 105 SD). For fisheries, we recommend a minimum catch size over 237.89 g drained weight to ensure that caught individuals are sexually mature. This study provides relevant information for the conservation and fishery management of A. chilensis. Continuous gametogenesis and high fecundity make this species particularly suitable for aquaculture in southern Chile.
