Multiple Origins of Sex Chromosomes in Nothobranchius Killifishes. [PDF]

Mol Ecol
ABSTRACT Sex chromosomes have evolved repeatedly across eukaryotes. The emergence of a sex‐determining (SD) locus is expected to progressively restrict recombination, driving convergent molecular differentiation. However, evidence from taxa like teleost fishes, representing over half of vertebrate species with unmatched diversity in SD systems ...

Mitigating the impact of winter temperatures on striped catfish (Pangasianodon hypophthalmus) using functional feed additives

Journal of the World Aquaculture Society, Volume 54, Issue 6, Page 1447-1467, December 2023., 2023
Abstract The drop in temperature during the winter months can lead to a decrease in growth, induce metabolic stress, and increase mortality incidences. The present study evaluated the potential of functional feed additives in mitigating the negative impacts of winter‐rearing conditions in striped catfish (Pangasianodon hypophthalmus).

Optimizing a metabarcoding marker portfolio for species detection from complex mixtures of globally diverse fishes

Environmental DNA, Volume 5, Issue 6, Page 1589-1607, November 2023., 2023
We assessed the performance of 22 DNA metabarcoding primer sets for detecting 103 species of marine and freshwater bony fishes, elasmobranchs, cephalopods, and crustaceans. We find that a portfolio of four markers targeting 12S, 16S, and multiple regions of COI identifies all reference taxa to family and nearly 60% to species.

A meta‐analytic review of monoterpene for fish anaesthesia

Fish and Fisheries, Volume 24, Issue 3, Page 367-380, May 2023., 2023
Abstract The use of anaesthetic agents has been increasing to address the welfare needs of different fish species in scientific and aquaculture practices. MS‐222 is the most used synthetic anaesthetic but some limitations and side effects have been reported.

Diversity of Fish Species in relation to Climatological Fluctuations in a Coastal River of Bangladesh

Journal of Marine Sciences, Volume 2023, Issue 1, 2023., 2023
In the Sandha river of Bangladesh, we investigated the temporal and geographical fluctuation in species of fish composition and diversity. The extent of our understanding of the fish variety in this river varies greatly on both a temporal and a geographical scale.

Patterns of Fish Assemblage, Growth, and Diet Composition in a Tropical River between Two Cascading Hydropower Dams

International Journal of Ecology, Volume 2021, Issue 1, 2021., 2021
Construction of cascade dams has been shown to have impacts on fish assemblages and biodiversity. Yet, there is no literature on fish assemblages in the Murum River that connects the cascading Bakun and Murum dams in Sarawak, Malaysia. Hence, study on this modified ecosystem is necessitated to better understand the effects of the cascade dam ...

Speciation in Thaparocleidus (Monogenea: Dactylogyridae) parasitizing Asian Pangasiid catfishes. [PDF]

Biomed Res Int, 2013
The phylogeny of monogeneans of the genus Thaparocleidus that parasitize the gills of Pangasiidae in Borneo and Sumatra was inferred from molecular data to investigate parasite speciation. The phylogeny of the Pangasiidae was also reconstructed in order to investigate host‐parasite coevolutionary history.

SYSTEMATIC REVISION OF THE GENERA OF PANGASIIDAE (SILURIFORMES, OSTARIOPHYSI)

Indonesian Aquaculture Journal, 2008
The family Pangasiidae belongs to the suborder Siluroidei, order Siluriformes, and suborder Ostariophysi. Since the groups were established as Pangasiini Bleeker, 1858; its content and classification have been greatly changed. Judging from the literature, the main constraint to cultivate wild species and to optimize the production of cultured species ...

Similarity and genetic relationship analysis of 28 species of Pangasiidae (Siluriformes, Ostariophysi)

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Pangasiid catfishes have most diverse morphotype among members in the family. In the past, misidentification often occurred for the species definition. After numerical taxonomy developed, the level of similarity or phenetic analysis was used to distinguish different taxa.
