    The biology and fishery potential of palinurid lobsters in Tanzania.
    (University of Dar es Salaam, 1973) Bwathondi, Philip Odoyo Joseph
    Representatives of the crustacean genus Panulirus are widely distributed throughout the Indo-West Pacific waters. This genus is represented by five species in Tanzanian coastal waters. The five species, in the order of their abundance, are P. ornatus, P. homarus, P. versicolor and P. penicilillatus. The habitat of the adults and the larvae of each species are investigated and discussed. Length/weight relationships of both male and female P.ornatus and P.longipes have been determined. Females have been found to be slightly longer and heavier than the males (having the same carvapace length) of the same species. The gross and histological anatomy of the reproductive systems of both males and females of this genus were investigated by vital staining techniques and by standard histological sectioning techniques. Function of each system was ascertained. Captive females were reared during and after breeding to determine the number of ovulations per breeding season, moulting cycle and growth per moult. Following gonad maturity states and the abundance of barried and spent forms for one complete year, breeding season has been established. The improvement of the common methods employed in fishing and some conservation measures have been suggested.

    The current performance and prospects of the fish processing in the lake zone: a case study of fish processing factories in Mwanza.
    (University of Dar es Salaam, 1999) Bwathondi, Philip Odoyo Joseph
    The research was aimed at analyzing the problems facing processing industry and future prospects in the lake zone. The study is organised as follows; chapter one gives background information, statement of the problem, objective of the study and plan of the dissertation. Chapter two represents literature review. Chapters three and four provide research methodology and analysis and findings respectively. Chapter five represents conclusion and recommendation. The study intended firstly to look into problems that face fish processing industry in terms of social economic infrastructure and how these problems can be minimized. Secondly, the study will look into future prospects of this industry in terms of capacity utilization and marketing strategy. Lastly the study will look into the role played by the government in promoting this industry. The study found out that there is a number of problems facing this industry in the course of its daily operations. The crucial problems to this industry are shortage in supply of fish, poor infrastructure, higher tax imposed on the products, power and water shortage; and the frequent ban to export the product from this industry. In order to solve these problems the following recommendations are proposed to be fulfilled by the government: first to reduce tax that is imposed on fish and fish products so as to make them fairly competitive to both internal and external markets; secondly, to improve socio-economic infrastructure; thirdly to help this industry in international markets, to fight for better price; and lastly, to improve working environment to the fish industry.
