(Springer Nature Switzerland AG., 2016-03-23)
Small estuaries and non-estuarine habitats harboring mangroves are very important ecosystems which provide important ecosystem goods and services; such as provision of ecological niches for juvenile fishes and invertebrates, ...
Fisheries Statistics for Lake Victoria, Tanzania
(Springer Nature Switzerland AG., 2017-11-29)
Time series fisheries statistics data mainly from Frame Surveys, Catch Assessment Surveys and Fisheries Annual Statistics Reports for Lake Victoria from 1967–2016 were collected from the Fisheries Development Division in ...
Small Scale Fisheries Management: Lessons from Cockle Harvesters in Nicaragua and Tanzania
(Taylor & Francis Online, 2010-06-01)
The role of women in gleaning fisheries tends to be underestimated and poorly documented although they play an important role in coastal food security and income generation. This article describes two initiatives for ...
The decline in phytoplankton biomass and prawn catches in the Rufiji-Mafia Channel, Tanzania
(African Journals Online, 2016-11-27)
The world’s oceans have seen significant declines in phytoplankton-the primary food source in the marine environment. This decline in primary producers is likely to impact the food chain and functions of most coastal and ...
Seasonal and spatial variation of surface current in the Pemba Channel, Tanzania
(PLOS ONE, 2019-01-07)
The surface current speeds within the Pemba channel were examined using 24 years of drifter data received from the Global Drifter Program. This study aimed to uncover varying surface current in the Pemba Channel in different ...
Coastal upwelling and seasonal variation in phytoplankton biomass in the Pemba Channel
(African Journals Online, 2021-02-11)
This study was conducted in the Pemba Channel off Tanga Region in northern Tanzania to investigate physical and
chemical factors that drive changes in phytoplankton biomass. Three transects off Mwaboza, Vyeru and Sahare ...

(African Journals Online, 2018-12-11)
Chlorophyll-a (Chl-a) concentrations were measured at four sites around Unguja, Zanzibar during the northeast (NE) and southeast (SE) monsoon seasons. Data for Chl-a, nitrate, phosphate, ammonia, dissolved ...
Environmental Changes in the Tanzanian Part of Lake Victoria
(Springer Nature Switzerland AG., 2017-11-29)
Lake Victoria is known for its explosive speciation and recent time hybridization, which is highly mediated by deterioration of water quality. This chapter summarizes the knowledge on change of water quality and environment ...
Co-management of Lake Victoria Fisheries
(Springer Nature Switzerland AG., 2017-11-29)
There have been concerns about the declining fish catches and fisheries ecosystem health for a number of fisheries including Lake Victoria. Consequently, a co-management system has been introduced as a means of, among ...
Using fishers’ local ecological knowledge for management of small-scale fisheries in data-poor regions: Comparing seasonal interview and field observation records in East Africa
(Elsevier, 2023-08)
Fishers, scientists and policy makers need to describe, understand and “agree on” variations in fish catches caused by exploitation and climate change for effective fisheries management. To achieve this, relevant data with ...
