International Journal of Limnology

International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives.

Journal founded by University Paul Sabatier, Toulouse in 1964.

  • Assessment of the age and growth of three fin fish species from a tropical estuary (Cochin, west coast of India)

    Show short summary

    This work provides the first information about the stock status of three fin fishes (Caranxheberi, Etroplussuratensis, and Oreochromis mossambicus) from this estuary. According to prior research, this estuary has seen a species reduction over time. It is vital to first learn about the stock status of the studied species because it is one of the most fished finfish species in this estuary. This study's findings will help formulate sustainable resource management.

  • Determination of fishing efficiency and selectivity of multifilament trammel nets in pearl mullet, Alburnus tarichi (Güldenstädt, 1814), fishing in Lake Van, Turkey

    Show short summary

    Pearl mullet is an endemic fish species living in the Van Lake Basin. Furthermore, it is an important species for both the region and Turkey, as it is the most caught fish in inland waters. Therefore, the sustainability of fishing is of utmost importance in terms of fisheries management. This study aimed to determine the the selectivity of multifilament trammel nets in pearl mullet, Alburnus tarichi (Güldenstädt, 1814), fishing in Lake Van. In line with this objective, the multifilament trammel nets with the mesh sizes of 20, 22 and 24 mm were tested. The “SELECT” method was applied to determine the selectivity parameters. According the results, the lengths of the optimum catching using nets with 20, 22 and 24 mm mesh sizes were calculated as 20.76 cm, 22.07 cm and 24.11 cm, respectively. The highest average CPUE in weight was found to be 24 mm (6.007 kg / 100 m / day). Considering the data obtained in the present study, in pearl mullet fishing, the best optimum catch length and CPUE values were determined in multifilament trammel nets with 24 mm mesh size. In conclusion, the present study suggests that the use of 24 mm mesh size in Lake for pearl mullet fishing will be more beneficial in terms of both fish stocks and the local fishermen.

    Impact of altitude on spring macroinvertebrates and water quality in South West region of Cameroon

    Show short summary

    We evaluated the impact of altitude on the biodiversity and water quality of 13 springs located from 82 to 1,189m a.s.l. on Mount Cameroon. Despite lower temperature and more oxygen at higher altitudes, diversity, including EPT did not increase. Therefore, African fauna reacts similarly to the faunas of other areas of the world. African species appear to be well adapted to warm and poorly oxygenated water compared to species from other parts of the world.

    Which barcode to decipher freshwater microalgal assemblages? Tests on mock communities

    Show short summary

    Microalgae taxa can be identified with short DNA barcodes. Eight primer pairs for 16S and five for 23S were tested in silico and with mock communities including cyanobacteria and eukaryotic microalgae. We conclude that the 23S primer pair ECLA23S_F1/ECLA23S_R1 was the best candidate to decipher freshwater phytoplankton communities.

The increasing of maximum lake water temperature in lowland lakes of central Europe: case study of the Polish Lakeland

Show short summary

The study showed significant changes in the maximum annual water temperatures in post-glacial lakes located in Poland in the years 1971-2015. The highest rate of increase in monthly maximum water temperature was recorded in April and the lowest in January and February. The value of maximum water temperature trends was lower than annual air temperature trends.

Longitudinal distribution of macroinvertebrate in a very wet North African Basin: Oued Melloulou (Morocco)

Show short summary

The Melloulou River presented 161 invertebrate taxa, most new for northeast Morocco. Multivariate analyses showed an invertebrate distribution governed by altitude, slope and current velocity in a highly flow dynamic. Three assemblages and a great number of ubiquitous taxa were also found. These findings are of crucial concern for managing actions.

Effects of herbicide mixtures on freshwater microalgae with the potential effect of a safener

Show short summary

Eleven agrochemicals tested on a microalga included a safener added in specific agrochemical formulations. One molecule was 2-fold more toxic than the mixture of all compounds. The safener decreased the toxicity of this herbicide that contains a halogen atom.

Occurrence of potentially toxic cyanobacteria Microcystis aeruginosa in aquatic ecosystems of central Kerala (south India)

Show short summary

The occurrence of M. aeruginosa bloom in two freshwater ponds along central Kerala has been addressed along with the variations in the hydrobiological characteristics of the ecosystem during bloom and non-bloom conditions of the species. Histological studies highlight hepatotoxicity of M. aeruginosa signifying regular monitoring of bloom events in these ecosystems.

Effects of mixing intensity on colony size and growth of Microcystis aeruginosa

Show short summary

Except for the highest mixing intensity group (1.28 m s−1), the colony sizes and growth rate of M. aeruginosa in mixing intensity groups (0.16, 0.32, 0.64 m s−1) was significantly higher than those in controls. This study suggested that modest mixing can significantly influence colony size and the growth of M. aeruginosa in freshwater ecosystem.
