Comparative study on the catch efficiency and size selection of entangling nets in Lake Kainji, Nigeria [PDF]

, 2005
The relative catch performance and selectively of gillnets and trammel nets were investigated in 12 sampling stations in Lake Kainji, Nigeria. 3 types of nets with dimensions 50mx3m were constructed using 76mm and 178mm meshsizes for two gillnets, 76mm ...

Growth Performance of Asian Seabass (Lates calcarifer, Bloch) in Relation to Stocking Density: Initial Results From Seabass Culture in Open Sea Floating Net Cages in the Cox's Bazar Coast, Bay of Bengal, Bangladesh

Aquaculture, Fish and Fisheries, Volume 4, Issue 6, December 2024.
ABSTRACT The study aimed to assess the impact of stocking density on the growth performance, survival rate and production of seabass (Lates calcarifer) fingerlings in floating net cages conducted at the Maheshkhali Channel, Cox's Bazar, Bangladesh. A triplicate group of seabass, with an average initial weight of 86.82 ± 1.9 g, was randomly stocked in ...

Length-weight relationship and condition factor of Centropomus viridis(Actinopterygii: Perciforms: Centropomidae) in the north coast of Nayarit

Acta Universitaria, 2020
This study poses two objectives: to determine whether the growth of females and males of the C. viridisis isometric, and whether the commercial fishing changes the condition of snook. The information regarding the length-weight relationship

Hyperostosis in Fishes: An Update With New Species Records

Journal of Morphology, Volume 285, Issue 11, November 2024.
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

Evolution of rhodopsin in flatfishes (Pleuronectiformes) is associated with depth and migratory behavior

Journal of Fish Biology, Volume 105, Issue 3, Page 779-790, September 2024.
Abstract Visual signals are involved in many fitness‐related tasks and are therefore essential for survival in many species. Aquatic organisms are ideal systems to study visual evolution, as the high diversity of spectral properties in aquatic environments generates great potential for adaptation to different light conditions.
