Genetic diversity and spatial population structure of a deepwater snapper, Pristipomoides filamentosus in the south-west Indian Ocean.

The crimson jobfish, Pristipomoides filamentosus Valenciennes, 1830 is an economically important demersal species largely distributed in the Indo-Pacific region. Pristipomoides filamentosus constitutes a significant portion of catch landed in demersal fisheries throughout the species' distribution range. Despite the species' economic importance, there is insufficient data to guide the species' conservation management, especially within the south-western (SW) Indian Ocean region.

Molecular phylogenetic analysis of the catfish species Auchenoglanis occidentalis (Valenciennes, 1840) (Pisces: Claroteidae) from Lake Turkana in East Africa: taxonomic implications.

Cytochrome c oxidase subunit I (COI) gene sequences of two specimens here recognized as Auchenoglanis occidentalis from Lake Turkana in the Ethiopian section were determined. A COI gene-based phylogenetic analysis was performed for these along with sequences of African catfish species from the family Clarotidae available in GenBank. Based on results of this analysis, it is concluded that (1) the currently identified A.

An important natural genetic resource of Oreochromis niloticus (Linnaeus, 1758) threatened by aquaculture activities in Loboi drainage, Kenya.

The need to improve food security in Africa through culture of tilapias has led to transfer of different species from their natural ranges causing negative impacts on wild fish genetic resources. Loboi swamp in Kenya is fed by three hot springs: Lake Bogoria Hotel, Chelaba and Turtle Springs, hosting natural populations of Oreochromis niloticus. The present study aimed at better genetic characterization of these threatened populations.

Phylogeny of suckermouth catfishes (Mochokidae: Chiloglanis) from Kenya: the utility of Growth Hormone introns in species level phylogenies.

African suckermouth catfishes (Mochokidae: Chiloglanis) occur in freshwater throughout tropical Africa. Specimens from all major drainages across Kenya were collected over three field seasons. Here we present a phylogeny inferred from both mitochondrial cytochrome b (cyt b) and introns of the nuclear Growth Hormone gene (GH).

Functional microsatellite and possible selective sweep in natural populations of the black-chinned tilapia Sarotherodon melanotheron (Teleostei, Cichlidae).

The Prolactin I (PrlI) gene is a key locus involved in fish osmotic regulation. Two microsatellites, PrlI GT and PrlI AC, are present in the promoter region of this gene in tilapias. One of these microsatellite is associated to PrlI gene expression and growth rate.
