Coral reef fish reproduction, species, fish length and weight, and others within New Ireland Province, Papua New Guinea from 2015-03-12 to 2015-03-23 (NCEI Accession 0144344)
Natural-resource professionals performed novel research on the reproductive biology of exploited reef fishes. Each participant produced reproductive data for a single target species, yielding new information for four species. These data can be used to describe: length-weight relationships (including sex-based differences), size-at-maturity for each sex (minimum size-at-maturity, and size-at-50%-maturity), reproductive mode (total vs batch spawning, gonochorism vs hermaphroditism), sex ratios (overall and size-specific), length-fecundity relationships, and reproductive periodicity (lunar, seasonal).
The fish were taken in the coral reef ecosystem for the area west and south of Kavieng, New Ireland Province, Papua New Guinea in March 2015. Specific site location of each catch was not given. About 90% of the catch was near Mait Island.

Purpose | The overall objective of the project was to train a cadre of natural-resource professionals from US-associated Pacific Islands (Hawaii, Guam, American Samoa, Commonwealth of the Northern Marianas Islands, Federated States of Micronesia, Republic of the Marshall Islands, and Palau) to use newly developed methods for rapid, low-cost, reproductive analysis of coral-reef fishes. These methods require minimal research infrastructure and are suitable for use on participants' home and neighboring islands. Basic reproductive information (e.g., size at maturity) is lacking for most fishes (Froese & Binohlan 2000). This problem is especially acute for coral-reef fishes. The sheer diversity of coral-reef fishes, the supposed cost associated with the reproductive analysis of each species, and the lack of expertise and research infrastructure in developing Pacific Island nations (where most coral reefs are located) are often cited as barriers to obtaining this important base-line information (Roberts & Polunin 1993, Johannes 1998, Froese & Binohlan 2000). These problems hinder current abilities to effectively manage coral-reef fisheries in the Pacific. To address these issues, Longenecker et al. (2013) developed a method for rapid, low-cost, on-site, histology-based reproductive analysis that requires minimal research infrastructure. With this method, reproductive information can be generated quickly, and its low cost eliminates one of the arguments against broad-scale reproductive analysis surveys. Training a new crop of fish reproductive biologists who can independently use this method will increase the rate at which new reproductive information is generated, thus increasing the potential to effectively manage and conserve Pacific coral-reef fishes. The data presented here can be used to generate and disseminate novel reproductive information for commonly exploited Pacific reef fishes, including: 1) Length-weight relationships, 2) Size-at-maturity, 3) Reproductive mode, 4) Size-specific sex ratios, 5) Size-fecundity relationships, and 6) Reproductive periodicity. |
