Sabaki fishing serial#

This low-lying area is bounded by higher land to the east and west and to the south by a dune system bordering the Indian Ocean. Tana River Delta: The delta is roughly triangular in shape, with its apex at Lake Bilisa (north of Garsen) and its base a 50 km stretch of beach along Ungwana (or Formosa) Bay, stretching from Kipini in the north-east to Mto Kilifi in the south-west. Tana Forests are riparian forests along the meandering course of the lower Tana River, some 350km east of Nairobi and 240km north of Mombasa both areas are described in details below. The Tana Delta is the name loosely given to the floodplain ecosystem of the lower Tana River, a vast wetland complex on the Kenyan coast.

Sabaki fishing serial#

We proposed the two sites to be considered for serial nomination into the world heritage list. Further research is required to further expound on the values of this area. This area represents a number of unique sites which may be nominated as serial sites.

The Tana delta and the Tana forest which include the Boni, Dondori, Lunghi, Lower Tana forest, Lango ya Samba Witu forest and the Tana delta provide unique ecosystem that is the Northern limit of Eastern Arc Mountains and Coastal Forests biodiversity hotspot.

The concentration ranges of the residues of dieldrin, lindane and DDE were comparable with those obtained in fish from Tana River in Kenya but the other residues of aldrin, endosulfan, DDD, and DDT were much higher than those detected in fish from River Tana.Tana River Delta: S02 30 E40 20 Tana Forests: S02 30 E40 30 Overall, the concentration ranges of some of the residues such as DDT, DDE, and DDD were comparable with those reported earlier for fish samples from Lake Kariba in Zimbabwe but concentration ranges of lindane and aldrin were much higher than those reported in fish from Lake Kariba. This conclusion was also supported by high BCF values of lindane in fish sampled in Sabaki and of aldrin sampled from Kilifi and Ramisi. The high DDT/DDE and aldrin/dieldrin concentration ratios also indicated that the sources of these residues were recent. This seasonal variation was particularly observable in p,p′-DDT residues which were only detected in samples taken in the rainy season but none in the dry season in all the sampling sites.

Seasonal variation in concentration of residues detected in fish samples was clear, with higher residue levels being recorded in the rainy season in May compared with those detected in the dry season in January. The concentration ranges obtained in fish in this study indicate that Mombasa Old Town was least contaminated by organochlorine residues as higher residues were detected near Malindi, at Funzi Lazy lagoon and at Kilifi creek which were near the confluences of Rivers Sabaki, Ramisi and Goshi at the Indian Ocean coast, indicating that the sources of the residues in fish the Indian Ocean coast were through discharge from the rivers. Considering all the four sampling sites in the two sampling seasons, the ranges of concentrations of residues detected in the fish samples (in µg kg −1 wet weight) were: lindane 16.1 (in sample from Mombasa)–1445 (Sabaki), aldrin 1.55 (Kilifi)–323 (Kilifi), dieldrin 4.81 (Ramisi)–109 (Sabaki), endosulfan 5.91 (Mombasa)–54.6 (Sabaki), p,p′-DDT 9.11 (Mombasa)–29.3 (Kilifi), p,p′-DDE 1.94 (Kilifi)–97.5 (Sabaki) and p,p′-DDD 1.68 (Mombasa)–98.9 (Kilifi). Organochlorine pesticide residues were analyzed in samples of fish taken from four different locations along the Indian Ocean coast of Kenya.
