[Abundance variations of fishes from sites with different levels of pollution in the sublittoral sector of Havana City, Cuba].

The impact of human activity affects fish populations. We studied the abundance of three selected fish species (Stegastes partitus, Thalassoma bifasciatum and Halichoeres bivittatus) in four sites with different degrees of pollution in Havana City: 30th street and 16th street; Miramar; Red Boy of Havana Bay; and the ending ofAlmendares's River. The sites were divided into five zones depending on their bottom characteristics.
