BackgroundClupeid fisheries in Lake Tanganyika (East Africa) provide food for millions of people in one of the world’s poorest regions. Due to climate change and overfishing, the clupeid stocks of Lake Tanganyika are declining. We investigate the population structure of the Lake Tanganyika sprat Stolothrissa tanganicae, using for the first time a genomic approach on this species. This is an important step towards knowing if the species should be managed separately or as a single stock… 
Structural genomic variation leads to unexpected genetic differentiation in Lake Tanganyika’s sardines
Reduced representation genomic sequencing methods used to gain a better understanding of genetic structure among and within populations of Lake Tanganyika’s two sardine species reveal unexpected differentiation within both S. tanganicae and L. miodon.
Structural genomic variation leads to genetic differentiation in Lake Tanganyika's sardines
Reduced‐representation genomic sequencing methods used to gain a better understanding of genetic structure among and within populations of Lake Tanganyika's two sardine species reveal differentiation within both S. tanganicae and L. miodon, and indicate rapidly evolving XY sex determination in the two species.
The genetic population structure of Lake Tanganyika’s Lates species flock, an endemic radiation of pelagic top predators
The population genetics of four endemic Lates species of Lake Tanganyika are investigated using reduced-representation genomic sequencing methods, finding the four species to be strongly differentiated from one another and evidence for strong genetic structure within L. mariae.
Sex differentiation and a chromosomal inversion lead to cryptic diversity in Lake Tanganyika sardines
This work uses reduced representation genomic sequencing methods to gain a better understanding of possible genetic structure among and within populations of Lake Tanganyika9s sardines, and reveals unexpected cryptic differentiation within both Stolothr Melissa and Limnothrissa.
Uncharted digenean diversity in Lake Tanganyika: cryptogonimids (Digenea: Cryptogonimidae) infecting endemic lates perches (Actinopterygii: Latidae)
The present study provides the first comprehensive characterisation of the digenean diversity in a fish family from Lake Tanganyika which will serve as a baseline for future explorations of the lake’s digenesan fauna.
Spatial and seasonal variation in reproductive indices of the clupeids Limnothrissa miodon and Stolothrissa tanganicae in the Congolese waters of northern Lake Tanganyika
Knowledge on the reproductive biology of the endemic clupeids Limnothrissa miodon and Stolothrissa tanganicae, two main target species of the pelagic fisheries of Lake Tanganyika, is constrained by
Isotopic signatures induced by upwelling tag regional fish populations in Lake Tanganyika
It is demonstrated that the pelagic fish of Lake Tanganyika form regional populations on a seasonal to multiannual time scale, and the development of basin-scale ecological differences in response to the prevailing hydrodynamic regimes may be inhibited by lake-wide gene flow on the long term.

Mitochondrial phylogeography of rock-dwelling cichlid fishes reveals evolutionary influence of historical lake level fluctuations of Lake Tanganyika, Africa.
The phylogeographic pattern of eretmodine cichlids suggests that major fluctuations in the level of the lake have been important in shaping their adaptive radiation and speciation, and the mitochondrially defined clades are in conflict with the current taxonomy of the group.
Limnological variability and pelagic fish abundance (Stolothrissa tanganicae and Lates stappersii) in Lake Tanganyika
A close correspondence between phytoplankton blooms at the time of trade winds changes and increased catches of S. tanganicae in the south is observed and remote sensing has shown a potentially interesting application for fisheries research at Lake Tanganyika.
Only true pelagics mix: comparative phylogeography of deepwater bathybatine cichlids from Lake Tanganyika
This work addresses the link between panmixis and pelagic habitat use by comparing the phylogeographic structure among four deepwater cichlid species of the tribe Bathybatini from Lake Tanganyika and shows that the mitochondrial genealogies of the four species are very shallow and that all species experienced recent population growth.
Growth, Recruitment and Reproduction of Sardines (Stolothrissa tanganicae and Limnothrissa miodon) in Northwestern Lake Tanganyika.
Life histories of two cJupeid fish species in northwestern Lake Tanganyika were studied, suggesting that they possess a lower level of reproductive effort and an increase in the mesh size of the commercial fishing net is effective in enlarging the exploitable fish biomass.
Big fish, little divergence: phylogeography of Lake Tanganyika’s giant cichlid, Boulengerochromis microlepis
The shallow divergence within the species may be related to a possibly large variance in reproductive success in this highly fecund species, and Trophic niche space restriction by sympatric piscivores, lack of geographic structure, low potential for sexual selection arising from the monogamous mating system and extinction may have contributed to keeping the lineage monotypic.
The larval fishery on Limnothrissa miodon in the Congolese waters of Lake Tanganyika: Impact on exploitable biomass and the value of the fishery
Declining catches of freshwater clupeids in Lake Tanganyika have recently led to widespread illegal fishing on the clupeid larvae with mosquito nets. This paper examines whether this larval fishery
Phylogeography and historical demography of the Pacific Sierra mackerel (Scomberomorus sierra) in the Eastern Pacific
The population genetic structure detected for the Pacific Sierra mackerel is associated with a limited dispersal between the main abundance areas that are usually linked to the spawning sites of the species.
Reproductive activities of two zooplanktivorous clupeid fish in relation to the seasonal abundance of copepod prey in the northern end of Lake Tanganyika
It is concluded that the timing of reproductive activities in these clupeids is species-specific, and might be subject to strong year-to-year variation.
Growth and Mortality of Stolothrissa tanganicae
Abstract Stolothrissa tanganicae, an endemic clupeid of Lake Tanganyika (East Africa), dominates ring-net and traditional fisheries in most years, cycling from a low in catches in the first half of
