Impacts of Global Warming on Quality of Male Fishes: Evidence From A Meta‐Analysis of Temperature Effects on Sperm Motility Kinematics

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Studies have demonstrated adverse effects of global warming on aquatic ecosystems. However, the effects of increased water temperature (IWT) on fish reproduction are still doubtful in species spawning at low or high temperatures. In this meta‐analysis, we elucidated the effects of global warming on spermatozoa functions, key determinants of ...

Structural Analysis of Embryonic Development of Embryos From the Crossing of Two Species of Siluriform

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Based on the need for knowledge about the biology of hybrid fish specimens currently being produced by commercial fish farmers, this study aimed to study the initial ontogenesis up to the fifth day after larval hatching of the Hybrid LP produced by crossing Leiarius marmoratus (♀) and Pseudoplatystoma reticulatum (♂), thus producing important data for ...

Transmission Behavior of B Chromosomes in Prochilodus lineatus (Characiformes, Prochilodontidae).

open access: yesCytogenetic and genome research, 2016
The population of Prochilodus lineatus found in the Mogi-Guaçu River is karyotypically polymorphic, carrying acrocentric, metacentric, and submetacentric B chromosomes. The analysis of each B chromosome frequency in this species revealed a variation in the distribution pattern, with the metacentric type having the highest frequency (73.30%), followed ...

Sperm Quality, Milt Biochemistry, and Cellular Ultrastructure in Fresh and Cryopreserved Sperm of Brycon amazonicus

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.
