“…This agrees with the justification of Riche and Garling [26], Pillay and Katty [4], El-Sayed [5], Lim et al [27] and Suresh and Bhujel [28]. They were explained that due to continuous feeding behaviour and smaller stomach capacity, tilapia respond better to more frequent feeding than other finfish and benefited from multiple daily feeding.…”

“…It must feed 3% to 4% of their body weight divided three to four times a day at the age of fingerlings. Board on Agriculture [33] in USA and Suresh and Bhujel [28] noted the nutrient requirements of fishes and identified the daily feeding allowance and frequencies for various species of fishes at different sizes. They stated that feeding condition factor is not affected by feeding frequency if the fish were fed four times or twice a day.…”

“…Results showed that the average un-ionized ammonia during the initial stage of the growing period were above the desirable level in all light manipulation and control treatment tanks, but for the succeeding growing periods, it was within the acceptable level [4]. However, control tanks recorded high levels of un-ionized ammonia in the afternoon until the 43 rd day of growing period, and during this period higher temperature and pH levels were also recorded which resulted to high mortality in these tanks (Fig.…”

Abstract. The study aimed to evaluate the effect of modified photoperiods and light intensities on grow-out production of tilapia under indoor tank culture system; specifically on water quality and on growth performance of tilapia. The study was conducted inside the greenhouse and considered two factors: photoperiod (24L:0D, 20L:4D and 16L:8D); and light intensity (40 watts m -2 , 60 watts m -2 and 80 watts m -2 ); also, a control treatment was set-up outside the greenhouse to receive the normal environmental condition. Light manipulations inside the greenhouse were able to sustain the water quality within the desirable level for tilapia cultured in tank; while control tanks shows high water quality variation. Growth performance of tilapia cultured in tank responds positively in prolonged photoperiod at different light intensities. However, light manipulation gave insignificant difference on feed conversion ratio and survival rate compared to normal condition. Results indicated that 20-hours photoperiod and 40 watts m -2 light intensity is just enough to sustain the recommended water quality and better growth performance of the cultured tilapia in indoor tank system. It can be concluded that longer photoperiod and restrained light intensity can improved the growth performance of tilapia under indoor tank culture.

“…Commercial aquaculture is based on Nile tilapia species with an estimated production of 1,600 tons per annum. Nile tilapia is exotic to Zimbabwe having been introduced from north and central Africa (Suresh & Bhujel 2012). The Zimbabwean government has explored and consulted on establishing aquaculture.…”

Literature on strategic management has been recently criticised for not being able to explain the success of a number of companies. Within this context, this paper has two main objectives: first, to assess whether one of the most comprehensive strategy models, Porter's diamond (1990) remains valuable to analyse the competitiveness of the Zimbabwean aquaculture industry; and second to produce recommendations to improve the competitiveness of the Zimbabwean tilapia industry. This study uses an intensive research approach, by means of indepth personal interviews with stakeholders from the selected industry. The results of this study indicate that 26 years after its development, Porter's diamond remains a valuable tool to analyse the competitiveness of the Zimbabwean aquaculture industry. Findings have revealed that the main strengths of the Zimbabwean tilapia industry are the availability of natural
