Fish and Fisheries, 2022 AbstractManagement of fish populations and ecosystems suffers from data and knowledge gaps, particularly with respect to how humans and nature affect dynamics at multi‐decadal and longer time scales. However, collection of new data which indicates population or ecosystem status is slow and expensive. Here we analyse c.

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]
J AnatA fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Genetically confirmed first records of an egg and a juvenile roundscale spearfish, Tetrapturus georgii. [PDF]
J Fish BiolAbstract The roundscale spearfish (Tetrapturus georgii) is a poorly studied species with limited information available on its biology, ecology, and population status. Although the adult life stage of the species is morphologically distinguishable from closely related species such as the overexploited white marlin (Kajikia albida), misidentification is ...

Revisiting Eothyrsites holosquamatus Chapman (Trichiuroidea: Gempylidae), an Eocene gemfish from the Burnside Mudstone, Dunedin, New Zealand. [PDF]
J R Soc N ZABSTRACT The remains of a unique fossil bony fish were discovered in late Eocene (39.1–36.7 Ma: NZ Kaiatan stage) mudstone at Burnside near Dunedin, New Zealand in the 1930s and subsequently named and described by Frederick Chapman. He interpreted the type specimen as being a large‐scaled relative of the modern Thyrsites of the Gempylidae (Scombroidei:

A synthetic control approach to estimate the effect of total allowable catches in the high seas
Fish and Fisheries, Volume 24, Issue 4, Page 635-651, July 2023., 2023 Abstract Total allowable catch restrictions (hereafter referred to as catch quotas) play an important role in maintaining healthy fish stocks. While studies have identified a positive relationship between catch quota implementation and improved stock status, these methods are subject to selection bias as catch quotas are typically applied to stocks ...

Marine and Coastal Fisheries, Volume 15, Issue 2, April 2023., 2023 Abstract Shortfin Mako Isurus oxyrinchus are ecologically and economically important apex predators throughout the global oceans. The eastern North Pacific Ocean contains several coastal nurseries for this species, where juveniles can forage and grow until venturing into offshore pelagic habitats, where seasonal migration and reproduction occurs ...

Papers in Palaeontology, Volume 8, Issue 6, November/December 2022., 2022 Abstract The Early Jurassic Posidonienschiefer Formation in south‐west Germany (Toarcian) records the first appearance of the stem‐teleost group Pachycormidae in the fossil record. However, most pachycormid taxa remain poorly diagnosed or undescribed, making questions of the morphological underpinnings of trophic diversification in the group difficult ...

Mapping small‐scale fisheries through a coordinated participatory strategy
Fish and Fisheries, Volume 23, Issue 4, Page 773-785, July 2022., 2022 Abstract The knowledge of small‐scale fisheries (SSFs) is important to develop management policies and mitigate the competition for marine resources. However, spatially explicit information is often unavailable at the regional and subregional scale.
