  abstract = {{F}or the last two decades, a rapid eutrophication process impacts {L}ake {T}iticaca, the largest tropical freshwater lake in {S}outh {A}merica and the main highest {G}reat {L}ake. {T}his is especially notorious in the {B}olivian sector of its shallow {L}ago {M}enor sub-basin. {L}ago {M}enor is deteriorated by the combination of multiple contaminations (domestic, industrial and mining) from untreated wastewater discharged from the urban area of {E}l {A}lto, indiscriminate overfishing, and climate change. {T}hese threats particularly affect the native {A}ndean killifish genus {O}restias, the ecology and dynamics of which require in-depth studies with non-invasive techniques. {H}ere, we use hydroacoustic method to evaluate fish patterns of distribution and abundance in the {L}ago {M}enor. {H}ydroacoustic data were collected during the 2015 rainy season ({N}ovember) with vertical beaming at 120 k{H}z along transects that sum a total length of 140 km. {O}ur results showed that the proxy of fish biomass was linked to {L}ago {M}enor bathymetry. {F}urthermore, the vertical fish biomass proxy was steady from 3 to 20 m. {T}his pilot study provides the first image of fish, mostly {O}restias spp., distribution and opens future studies to deepen knowledge on their ecology and ethology, and regular monitoring of their population and stock for the fisheries assessment in {L}ake {T}iticaca.},
