Coral restoration research and technical developments: what we have learned so far
Marine Biology Research, 2019Coral reef restoration is not the same as forest restoration as its success is not always guaranteed because of insufficient knowledge of coral biology. The technology of active restoration has a history of only 40 years or less. In spite of many devices

Few mature female bullseye puffer have been observed to spawn in captivity. The ovary appears to develop to late vitellogenesis, but not to complete final oocyte maturation (FOM). Luteinizing hormone releasing hormone analogue (LHRHa) treatment induced the spawning of good quality eggs in both wild and captive brood fish.

Biology, Spawning, and Movements ofCycleptus meridionalisin the Lower Alabama River, Alabama
Southeastern Naturalist, 2015Abstract The goals of this study were to describe the biology, spawning season, and movements of Cycleptus meridionalis (Southeastern Blue Sucker) in the lower Alabama River, and evaluate possible spawning-site fidelity to Millers Ferry Lock and Dam.

Wild Seriola dumerilii were collected in the South Mediterranean Sea during the 1990, 1991 and 1992 spawning seasons. Macroscopic and cytological characteristics of ovary and testis were analysed. Depending on the presence and the number of oocytes at different stages, a five point maturity scale was proposed for ovarian maturity.

The reproductive biology of an open-water spawning Lake Malawi cichlid, Copadichromis chrysonotus
African Zoology, 2000Copadichromis chrysonotus is a zooplanktivorous cichlid member of the diverse fish community inhabiting Lake Malawi’s rocky, littoral habitat. Like most Lake Malawi cichlids, this species’ reproductive strategy is based on maternal mouthbrooding, but it is the only littoral species known to spawn in the open water without a substrate-based territory ...

The reproductive biology of Great Barrier Reef populations of the long‐lived grouperEpinephelus fuscoguttatus(brown‐marbled grouper or flowery cod) was investigated using histological analyses. Evidence provided by gonad morphology and age‐based demographics suggested monandric protogynous hermaphroditism. Younger age groups contained only immature and

We investigated the reproductive biology of Etheostoma chienense in the Bayou du Chien drainage of western Kentucky. Etheostoma chienense is similar in its ecology and reproductive biology to other members of the E. squamiceps complex. However, E. chienense is opportunistic in its choice of egg deposition substrates, as nests were found on a variety of

Biological data, size frequency distribution of intraovarian oocytes, maturity indices and histological observations of the gonads were used to assess the spawning cycle of S. brasiliensis, sampled September 1981–August 1982 throughout the main fishing area off the Brazilian coast (22°S to 28°S).

In the present study, life-history traits of importance to fisheries management were estimated for the forktail rabbitfish (Siganus argenteus) based on fishery-dependent samples collected over a 2-year period in the Commonwealth of the Northern Mariana Islands.
