“…Despite the fact that the sex ratio is 1:1 in most holothurians (Ramofafia, Byrne & Battangle, 2001;Asha & Muthiga, 2008;Fajardo-León et al, 2008;Kazanidis et al, 2010; Peters-Didier, Pardo, Garrido & Gallardo, 2018;Cahuzac et al, 2019), as in the Ría de Vigo, some species demonstrated an unbalanced ratio (Costelloe, 1985;Navarro et al, 2012;Omar, Abdel Razek, Abdel Rahman & El Shimy, 2013;Pañola-Madrigal, Calderón-Aguilera, Aguilar-Cruz, Reyes-Bonilla & Herrero-Pérezrul, 2017). In fact, Santos et al (2016) found in H. forskali, more female than males; these authors explain that the place of sampling is subject to strong tides which is considered to be another major factor affecting the balanced sex ratio due to the fact that strong sea waves often promote species´ evisceration as a stress response.…”

Introduction: The exploitation of the sea cucumber (Holothuria (Panningothuria) forskali) in Ría de Vigo (NW Spain) is recent (2015) and it has been done until now with scarce or no information about some key biological aspects as reproduction, recruitment or growth. Objective: To describe the reproductive cycle of H. forskali in Ría de Vigo. Methods: We sampled fortnightly throughout 2018. We calculated gonadal condition indices (GCI) and gametogenic stages by classic histological methods. Results: The reproductive cycle of H. forskali in the Ría de Vigo is characterized by a sexual resting stage during spring, when temperature and daylight hours are lower; the beginning of gametogenesis during summer, when temperature is higher, daylight hours longer and the sea bottom is rich in nutrients; then, a period of spawns interspersed with a gonadal restoration during autumn and winter, when temperature is lower and food is scarce. Sex ratio is 1:1, however, the studied population is not synchronized, because females initiate maturation earlier. The comparison of the histological results with GCI indices suggest that GCI is a good indicator for gonadal stage. Fishery management strategies, such as a closure period, must be adapted to the reproductive stage. We recommend avoiding fishing between November and February to increase spawning potential ratio and, consequently, recruitment.

“…As in other holothuroids, the process of gonad maturation can be seen as an increase in tubule length and diameter towards stage IV (mature) (Hamel et al, 1993;Catalan & Yamamoto, 1994;Foster & Hodgson, 1995;Hamel & Mercier, 1996a;Singh et al, 2001;Asha & Muthiah, 2008;Fajardo-León et al, 2008;Navarro et al, 2012) and decreased length toward stage V (Catalan & Yamamoto, 1994;Ramofafia et al, 2001;Toral-Granda & Martínez, 2007;Dissanayake & Stefansson, 2010;Navarro et al, 2012). Female tubule diameter was wider than males (Asha & Muthiah, 2008;Fajardo-León et al, 2008), while males had more tubule bifurcations than females. This difference could indicate a higher need for sperm production surface area in males and a need for wider tubule lumen space for oocyte storage in females.…”

“…Athyonidium chilensis gonad colours fit patterns described for other dendrochirotes; creamy white to orange male and green to brown female gonad (Costelloe, 1985; Hamel et al , 1993; Catalan & Yamamoto, 1994; Foster & Hodgson, 1995). As in other holothuroids, the process of gonad maturation can be seen as an increase in tubule length and diameter towards stage IV (mature) (Hamel et al , 1993; Catalan & Yamamoto, 1994; Foster & Hodgson, 1995; Hamel & Mercier, 1996a; Singh et al , 2001; Asha & Muthiah, 2008; Fajardo-León et al , 2008; Navarro et al , 2012) and decreased length toward stage V (Catalan & Yamamoto, 1994; Ramofafia et al , 2001; Toral-Granda & Martínez, 2007; Dissanayake & Stefansson, 2010; Navarro et al , 2012).

“…Athyonidium chilensis size at first maturity was slightly lower than that of the dendrochirote C. frondosa (55 g Ew) (Hamel & Mercier, 1996a), similar to that of the aspidochirote Isostichopus fuscus (161.0 and 170.9 g Dw) (Toral-Granda & Martínez, 2007), and considerably lower than that of the aspidochirotes Parastichopus parvimensis (120 to 140 g Ew) (Fajardo-León et al , 2008) and Holothuria sanctori (101 to 110 g Ew) (Navarro et al , 2012), all holothuroids of similar total length (Tl) to A. chilensis . When comparing the relationship between Tl and drained weight (Dw) against eviscerated weight (Ew) in A. chilensis , Dw was a much more reliable predictor of live animal weight, as observed for other sea cucumber species (Herrero-Pérezrul & Reyes-Bonilla, 2008; Dissanayake & Stefansson, 2010; Kazanidis et al , 2010).…”

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.

“…Although some pioneering research on the aquaculture of H. polii has resulted successfully (Rakaj et al, 2019;Tolon, 2017) but there is still scarce information on spawning period and gonadal development which are needed for breeding under controlled conditions. Entire studies on the reproductive biology of sea cucumber species clearly show that reproductive dynamics differ according to the geographical regions (Bulteel et al, 1992;Costelloe, 1988;Despalatovic et al, 2004;Despalatović et al, 2003;Fajardo-León et al, 2008;McEuen, 1988;Navarro et al, 2012;Tuwo and Conand, 1992;Valls, 2004). The effect of water temperature that determines the spawning period is prominent in the temperate zones like the Mediterranean, where seawater temperature significantly varies between regions (Conand, 1981;Costelloe, 1988;Despalatovic et al, 2004;Tuwo and Conand, 1992).…”

The Mediterranean sea cucumbers including Holothuria polii has become commercially important in international trade due to the high demand of consumers from Far East countries. Sea cucumbers fisheries is a valuable income for the regional fishermen but natural stocks endangered by overfishing in recent years. Fisheries regulations and aquaculture studies are important precautions for preserving natural stocks. All these efforts are based on reproduction biology of this species which slightly differed among regions. In this study, the reproduction biology including morphological characteristics, gonadosomatic index and gonadal development stages of H.polii at the eastern coast of Aegean Sea (Izmir, Turkey) were investigated during the reproduction (spawning) period from July to October 2018. Gonads and gonad sections of 60 sea cucumbers (120.60 ± 19.56 g) have been observed by macroscopic and microscopic inspections. Three gonadal development stages have been identified by histologic observations as mature (III), spawning (IV) and post-spawning stage (V) in gonadal tubules. Results indicate that both female and male gonads are at mature and spawning stage in July and all gonads are at post-spawning stage in October. The mean gonad weight was 12.53 ± 1.33 g at the beginning of the spawning period (July) and 1.87 ± 0.58 g at the end of the spawning period (October). Gonadosomatic index decreased from 17.53 ± 0.02% (July) to 3.37 ± 0.01% (October) after spawning. The gonadosomatic index, gonad weight, and spawning were related to the seawater temperature. According to this study, the spawning period of H.polii at the eastern coasts of the Aegean Sea starts in July and completely ends in October. As a result, the data related to the reproduction biology in spawning period of H.polii would guide stock management and artificial breeding of this species under controlled conditions.
