Bonga shad; Shad Facebook. However, many more fish were caught in Cocody Bay than in the unpolluted Sud Boulay Bay, except in Decemberwhen numerous juvenile S.
The only permanent ethamlosa with the sea is through the Vridi Canal, a channel m wide and 15 m deep constructed during the s. Black and white drawing: The stage of maturity was determined ethamlosa from the gonads, following the methods and descriptions of Fontana The three bays, all with similar relative environmental conditions Durand et al.
Summary page Point data Common names Photos. It may also be caught by gill nets. Les peuplements de poissons des milieux estuariens de L’Afrique de l’ouest: The three-tone grey scale is proportional to soil use: Ethmalosa fimbriata Bowdich, Pelvic finrays i 7; caudal fin fimrbiata long and pointed.
Retrieved 19 September Chemical pollution, mainly hydrocarbons, organochlorides, and heavy metals, is derived from agricultural and industrial activity in the adjacent watershed. These data were used to determine the size at first maturity Figure 4. Bonga is very important in West African coastal and lagoon fishing communities and it is an important food source in West and Central Africa.
Sounds Ciguatera Speed Swim. Breeds throughout year in waters of salinities 3. Rapid demographic growth in the city of Abidjan and associated burgeoning industrial activity are responsible for the increase in urban and industrial discharges into the Ebrie Lagoon, the Ivory Coast’s largest lagoon.
It breeds throughout the year in waters of salinities 3. Several questions arise from this fimbriara.
This can be taken as confirmation that Bietri Bay is highly polluted whereas Cocody Bay is mainly eutrophic urban pollution. Records from Cape Verde Islands based on erroneous type locality for E.
Short description Morphology Morphometrics Dorsal spines total: This page was last edited on 22 Marchat The size at first maturity was inversely related to the extent of pollution, the highest L 50 being associated with the unpolluted reference site and the smallest with the most polluted site.

Alosa species do not overlap E. Several studies have demonstrated the impact of increasing pollution on the environment itself, as well as on benthic macrofauna, heterotrophic bacteria, phytoplankton, and primary production Pages et al.
Other factors, such as predation pressure or geographic distribution, may trigger phenotypic plasticity and changes in size at first maturity Belk, ; Holopainen et al. The question still remains whether E.
Mean sizes were smallest in Bietri Bay 84 and Smoke-drying of fish is essentially a drying process to preserve the product in the absence of refrigeration.
The biology of the clupeid Ethmalosa fimbriata Bowdich was studied as a potential bio-indicator fimbriafa pollution in three bays of the Ebrie Lagoon, an inter-tropical lagoon in the Ivory Coast western Africa. More and up-to-date studies are clearly necessary to determine the age at first maturity and the age structure of E. Biomarker responses in whitefish Coregonus lavaretus L.
