“…In the Sacca di Goro, Asian date mussel gametogenesis initiates when the gonads probably have a minimum amount of reserves, and a continuous transfer of nutrient reserves is necessary for further growth and development of gametes; starvation and/or adverse environmental conditions during the period of gonad growth resulted in an absorption of oogonia and oocytes. Sastry (1966) obtained similar results while studying the effects of temperature and starvation on the gametogenesis of the scallop Aequipecten irradians. Oocyte degeneration and resorption in molluscs is a commonly observed phenomenon (Pipe, 1987;Dorange & Le Pennec, 1989), and may be brought about by a variety of natural environmental conditions such as extremes of temperatures, desiccation or low levels of nutrition.…”

“…Oocyte degeneration and resorption in molluscs is a commonly observed phenomenon (Pipe, 1987;Dorange & Le Pennec, 1989), and may be brought about by a variety of natural environmental conditions such as extremes of temperatures, desiccation or low levels of nutrition. An increase in temperature without availability of sufficient quantities of food may lead to resorption rather than proliferation of gametes (Sastry, 1966).…”

The reproductive cycle of the non-indigenous mytilid Musculista senhousia was studied over a one-year period in the Sacca di Goro, a lagoon in the Po River deltaic area, where the species was recently accidentally introduced. Four main stages were recognized: gonad spent, developing, ripe, and spawning. Oocytes in previtellogenesis appeared in March and coexisted with growing oocytes. Spermatogenesis preceded oogenesis, and sperm clusters were observed from May. Yolk-filled eggs were present from June, but, instead of being spawned, underwent summer degeneration. Conversely, spawning started in mid-September, coinciding with water temperature decrease, and lasted to November, after which the gonads were spent. The species is strictly gonochoric. Both the cohort-of-the-year and the survivors of the cohort-of-the-previous-year started maturation. Such an overlap of reproducing generations is probably an adaptation for survival in a variable environment. The reproductive output of M. senhousia was determined following stimulation trials using hydrogen peroxide. Emission of gametes was completed within 4 h, and a single female might release as many as 137·10 3 egg cells. Swimming D-shaped larvae appeared within 24 h of fertilization. Larval life had a duration of approximately 15-18 days.

Bay scallop (Argopecten irradians) has been farmed only in the South Sea of Korea. East Sea Fisheries Research Institute (ESFRI) has developed bay scallop aquaculture technologies to extend its aquaculture area to the Southeast Sea of Korea. For the artificial spawning, the water temperature was maintained at 23℃. Over 100,000,000 eggs were spawned through artificial spawning inductions, such as air exposure and thermal shock by rising the water temperature. The fertilization rate was over 91% with nearly 94,000,000 fertilized eggs. The shape of fertilized eggs was spherical with an average diameter of 61.7 ± 0.05 μm (54.1-67.4 μm). Five days after fertilization, the eggs developed into prodissoconch shell, and continuously grew into umbo stage and then umbones stage. After 8 days of fertilization, the size of larva became 179.7 ± 8.4 μm on average (150.4-204.8 μ m), and the larva formed a foot and an eye spot. The larvae grew to 235.4 ± 9.7 μm in 10 days and attached to adherence material, becoming juvenile bay scallop. The shells grew from 22.71 mm to 72.40 mm in 6 month (June-December). The total weight increased from 2.0 g to 32.7 g at the same period. The daily growth rates of young scallop were 0.35 mm d -1 (Apr. to Jun.) and 0.41 mm d -1 (Jun. to Aug.), which were comparable to those found in the South Sea. These findings suggest that the bay scallop aquaculture may be suitable in the Southeast Sea of Korea and may provide an additional crop to aquaculturists.

“…Development and Maturation Several authors (Sastry, 1966(Sastry, , 1968Chung et al, 1991Chung et al, , 2005Chung and Ryou, 2000) stated that exogenous factors (water temperature, food availability, salinity, day length, etc.) and endogenous factors (neuroendocrine activity) have been suggested as control factors for gonadal development and maturation in marine bivalves.…”
