“…Size and other physical cell characteristics (presence of umbonate larva, eyespot, double ring and foot) of S. limbatus larvae obtained in this study closely agree with those reported for S. tenebrosus (Parnell, 2002) and other Pectinoidea larvae, such as Argopecten ventricosus (Ibarra et al, 1997), Amusium balloti (Rose et al, 1988), Chlamys asperrimus (Rose and Dix, 1984), Nodipecten nodosus (De la Roche et al, 2002;Velasco et al, 2007) and Argopecten nucleus (Velasco et al, 2007). Nevertheless, our results diverge partially from those of Soria et al (2010), which reported longer sizes for pediveligers (234.0 ± 28.03 μm) than those obtained in the present study (185.2 ± 3.9 μm) for the same species.…”

“…The characteristics of sperm, collected after mollusk sperm shedding, were estimated in a few species: mussel (Mytilus edulis, Everett et al 2004;Jha et al 2007), Pacific oyster (Cosson et al 2008a;Suquet et al 2012) and sea urchin (Anthocidaris crassispina; Au et al 2000). Sperm fertilisation capacity of two Caribbean scallops (Argopecten nucleus and Nodipecten nodosus) was not influenced by stimulation technique, including temperature shock and serotonin or prostaglandin injection (Velasco et al 2007). …”

“…Bivalve sperm can be collected by gonad scarification but also by using different techniques to induce ejaculation (Velasco et al 2007). For example, sperm release of American oysters (Crassostrea virginica) was observed following a rapid temperature increase or after the addition of oocytes in seawater surrounding animals (Galstoff 1940).…”

-Sperm characteristics of scallops have not been well described in the scientific literature. The effects of sperm release technique (thermal shock versus serotonin injection), of sperm collection technique (testis sampling versus serotonin injection), of sperm sampling location along the genital tract, of in vitro sperm maturation, and of time post activation on scallop sperm characteristics were assessed in the present work. Whatever sperm release technique used, no significant differences were observed regarding the percentage of motile spermatozoa and the velocity of the average path (VAP). Compared to testicular sperm, a higher percentage of motile spermatozoa, VAP and intracellular adenosine triphosphate (ATP) content were observed for sperm shed after serotonin injection. From the distal part of testes up to the gonopore, an increase of the percentage of motile spermatozoa and VAP was assessed, suggesting a sperm 'maturation process' along the genital ducts. A higher increase in the percentage of motile sperm was recorded during a 5 min incubation of testicular sperm in seawater containing 2 mM serotonin and seawater containing 10 mM caffein compared to seawater (control). In addition, a higher VAP was assessed, incubating testicular sperm in caffein, compared to control or serotonin. Then, the percentage of motile spermatozoa, VAP and intracellular ATP content exhibited a progressive reduction during the 10 h swimming period. Mean values of the percentage of motile spermatozoa, VAP, sperm track linearity (LIN) and intracellular ATP content recorded at the beginning of the movement period for sperm samples collected after intragonadal serotonin injection, were 82 ± 7%, 162 ± 15 µm s −1 , 0.33 ± 0.12 and 212 ± 133 nmol ×10 −9 spermatozoa (n = 9 males), respectively. The present study confirms the existence of a sperm "maturation process" along scallop genital ducts. In addition, the cessation of scallop sperm movement can be explained by the exhaustion of ATP content at the end of the movement phase.

“…Gibbons & Castagna (1984) mostraron que el suministro de serotonina en ostras, ostiones y almejas genera gametos competentes, fecundables, y que se transforman en larvas y consecutivamente son capaces de metamorfosear, lo que también fue observado en Haliotis asinina (Wang et al 2010), Ilyanasa obsolete (Levantine & Bonar 1986) y Pinctada maxima (Zhao et al 2003) donde la serotonina fue el mejor inductor para supervivencia larval, asentamiento y metamorfosis. Esto también se observó en Tridacna gigas (Crawford et al 1986), Hippoper porcelanus (Alcazar 1987) y los pectínidos del Caribe Argopecten nucleus y Nodipecten nodosus (Velasco et al 2007). Hamida et al (2004) demostraron también la competencia de ovocitos para ser fertilizados en Ruditapes decussatus, después de inducir la ruptura de la vesícula germinal incubándolos con serotonina.…”

Abstract.-The effect of serotonin spawning stimulating agent, was evaluated in Ensis macha sexually mature broodstock, conditioned in laboratory. Neurotransmitter 0.9 ml at a concentration of 10 -5 M was injected into the foot of each specimen. 5-HT induced gamete release in 92% of injected broodstock, always producing the fastest response in males, removing sperm at 36 min (± 15.9) after injection. The release of mature oocytes began at 170 min (± 42.4) post-injection. Embryonic development to the veliger larva formation, straight hinge D had a survival of 88%, no malformations have been observed in larvae. In only one trial, fertilized oocytes were not viable. Finally, we can confirm that there is a pattern in the release of mature gametes E. macha broodstocks due to the action of serotonin 5-HT and could be a useful tool for aquaculture pr actices.
