From gametogenesis to spawning: How climate‐driven warming affects teleost reproductive biology

Journal of Fish Biology, Volume 97, Issue 3, Page 607-632, September 2020., 2020
Abstract Ambient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the reproductive function of fish, which has implications for wild population dynamics, fisheries and aquaculture.

Homology of the fifth epibranchial and accessory elements of the ceratobranchials among gnathostomes: insights from the development of ostariophysans. [PDF]

PLoS ONE, 2013
Epibranchials are among the main dorsal elements of the gill basket in jawed vertebrates (Gnathostomata). Among extant fishes, chondrichthyans most resemble the putative ancestral condition as all branchial arches possess every serially homologous piece.
