TERRITORIAL WATERS OF KENYA FISHERIES RESOURCES UNDER-EXPLOITED
The Fisheries Hydro-acoustics baseline survey of the Northern Kenya Banks and the Territorial Waters was conducted in Nov/Dec 2016 for 10 days.
Northern Kenya Banks covers two counties of Kilifi and Lamu starting from Malindi to Lamu in the coastline of Kenya. The Banks covers .......km2 with an average depth ranging between 180-200 meters. The yields average with .........licensed artisanal fishers and .........semi-industrial trawlers. The crustacean fishery targets prawns, lobsters, crabs, octopus/squids . The prawn trawling has been discontinued for the last ...years.
The characteristics of the Northern banks are;
It has high nutrient input from River Tana.
It is the convergence zone for the East African Coastal and the Somali currents with the resultant upwelling making it the most productive fishing grounds in the marine fishery sector.
Preliminary investigations based on frame survey between 1990-2012 indicated minimal increase in catches. The yields were ranging between112,000 mt and 200,000 mt with an exception high of 1,666,000 mt 1991.
The comparative survey between echograms generated from the EK60 with the above in situ points to unexploited fishery with probable factors ;
Lack information to inform the artisanal fishers.
Inadequate information to potential commercial investors to inform decision making.
Inaccurate data recording due to diminished capacity on catches.
Unwillingness fisher groups to provide accurate information.
The expected outcomes from the cruise after comprehensive data analysis are;
Mapping fishing grounds using EK60 echo-sounder to guide the fishers and potential investors.
Developing models to derive projections for future planning.
Identifying locations of marine mammals, birds and turtles as indicators of fish abundance.
Determining nutrient levels and the influence of;
• North East Monsoon and East African Coastal currents interactions.
• Temperatures and its contribution to nutrients.
• Chlorophyll concentrations and contributions to ocean fertility.
• Zoning upwelling areas based on different seasons.
• Generate data and knowledge management to guide the Marine Blue Economy.
