Coral spawning in the Gulf of Oman and relationship to latitudinal variation in spawning season in the northwest Indian Ocean. [PDF]

Sci Rep, 2014
Despite a wealth of information on sexual reproduction in scleractinian corals, there are regional gaps in reproductive records. In the Gulf of the Oman in the Arabian Sea, reproductive timing was assessed in four common species of broadcast spawning corals using field surveys of gamete maturity and aquarium observations of spawning activity.

Spawning Season of Important Bivalves in Ariake Bay-I

NIPPON SUISAN GAKKAISHI, 1954
1. The spawning seasons of Ostrea rivularis and O. gigas were determined by examining their body weight, maturation of gonads and discharge of the reproductive substances. 2. The spawning seasons of these two oysters do not cover well one another. 3. The spawning season of O. rivularis ranges from late May to early September. There are 3 major spawning

On the Spawning Season and Spawning Ground of the Japanese gizzard, Konosirus punctatus, in Lake Hamana.

NIPPON SUISAN GAKKAISHI, 1974
The spawning season and spawning ground of the Japanese gizzard shad, Konosirus punctatus, in Lake Hamana were estimated based on gonad maturity, seasonal and spatial distribution of spawned eggs, and catch statistics.The results obtained were as follows:1) The spawning season of the Japanese gizzard shad in Lake Hamana is believed to be from mid-April

Assessment of the food available to Cape anchovy during their spawning season [PDF]

South African Journal of Marine Science, 1997
The Cape anchovy Engraulis capensis spawns serially between September and February each year on the western Agulhas Bank, South Africa. Food availability in terms of copepod biomass is important for successfulspawning and subsequent recruitment. This note investigates the variability within a spawning season (1993/94 and 1994/95) of copepod biomass on ...
