Effect of stocking density on the growth and survival of Tilapia juveniles (Sarotherodon melanotheron) reared in happas at Layo station (Dabou, Côte d’Ivoire)

A study was carried out to evaluate the effect of stocking density on the growth and survival of Sarotherodon melanotheron juveniles. To do this, 300 individuals with an initial average weight 4.13 ± 1.96 g and an initial average length 5.79 ± 0.89 cm were monitored for 42 days, in triplicate, at four densities (0.2; […]

Length-weight relationships of Sarotherodon melanotheron melanotheron (Pisces: Cichlidae) in Benin (West Africa)

Length-weight relationship is of great importance in fishery assessments and biomass estimation. The present study reports length-weight relationships for six populations of Sarotherodon melanotheron melanotheron (Pisces, Cichlidae) captured in fresh and brackish waters in Benin (Lagoon of Porto-Novo, Lake Nokoue, Coastal Lagoon, Lake Aheme, Lake Toho and Dam SUCOBE). Nine hundred (900) individuals of S. […]

Ratio « number of males on number of females » for the mass production of Sarotherodon melanotheron’s fry in concrete tanks

The appropriate proportion of male and female parents that give a highest number of juveniles is a major concern in tilapia culture Sarotherodon melanotheron due to the oral incubation by males. A study of the ratio “number of males to number of females” on fingerlings production has been performed in order to determine the optimal […]

Influence of processing and preservation processes on technological and organoleptic qualities of Coptodon guineensis and Sarotherodon melanotheron in south Benin

Fish is one of the most important protein sources in Benin. Inappropriate processing and preservation processes could deteriorate fish quality traits. The study aims to evaluate the effect of processing and preservation processes on the technological and organoleptic qualities of fish in south Benin. Thus, 86 fish processors and wholesalers were surveyed. In total 120 […]

Effect of processing and preservation processes on microbiological quality of Coptodon guineensis and Sarotherodon melanotheron in South Benin

Fish is a very perishable foodstuff. The multiplication of the pathogenic germs is a problem of public health. The study aimed to evaluate the effect of processing and preservation processes on the microbiological quality of fish in south Benin. The study was carried out from June 2014 to December 2014. One hundred and twenty (120) […]

Ecological comparative approach of Sarotherodon melanotheron populations of lowlands dradged and costal lagoon at Togbin in Benin: Weight-Length relationship and condition factor

Lowland dredging has been booming in Benin since 2008 following the ban on the exploitation of marine sand due to coastal erosion. Dredging the hydrobiological influence of aquatic ecosystems and it is essential to understand its impact on the ecology of the fish fauna for future policies of development and protection of fisheries. It is […]

Spatial distribution of two gill monogenean species from Sarotherodon melanotheron (Cichlidae) in man-made Lake Ayamé 2, Côte d’Ivoire

This study describes the spatial distribution of two monogenean species, Cichlidogyrus halinus and C. halli on the gills of Sarotherodon melanotheron from man-made Lake Ayamé 2. A total of 96 S. melanotheron were sampled between July 2015 and April 2016. After sampling host, parasites were collected and mounted from each sector of the gill arch. […]

Population parameters and exploitation rate of Sarotherodon melanotheron melanotheron rüppell, 1852 (Cichlidae) in Lake Toho, Benin

Aspects of the population dynamics of Sarotherodon melanotheron melanotheron, which is a commercially important fish species in Lake Toho, were described based on 1558 specimens collected monthly between January and December 2012 from artisanal captures. The size at first maturity was estimated at 6.9 cm for males and 7.7 cm for females. The asymptotic length […]

Otolith morphology of six species of Cichlidae from Lake Buyo in the South-west of Côte d’Ivoire

The morphology of otoliths is used as an indicator of various ecological processes or properties. So the present study was aimed to provide baseline data on the morphology of otoliths in six species of Cichlidae. A total of 179 individuals belonging to six species of the Cichlidae fished in Lake Buyo in June 2021 by […]

Preliminary ichthyological inventory of Fresco lagoon (Côte d’Ivoire, West Africa)
