Growth performance of juveniles <i>Oreochromis niloticus</i> reared with two different diets in Kunduchi Ponds, Dar Es Salaam, Tanzania

Abstract

Comparative study was conducted to observe the growth performance, length and condition factor of Oreochromis niloticus fed with two different diets using standard methods and procedures. The fish were fed with two different formulated Kunduchi Locally processed Feed (KLF) for a period of six weeks. Maximum weight gain of (10.74 to 12.48 g) was recorded with Kunduchi locally feed (KLF) with specific growth rate of (5.56 to 6.37 % per day), while minimum w Feed (AAF) with specific growth rate of (5.14 to 5.73 % per day). observed during the whole experimental period. in the 'b' values among all the experimental ponds and the value of the exponent 'b' ranged from (2.38 to 4.03) indicating both negative and positive allometric growths. The condition factor 'K' of all the experimental fish was above 1.0 (1.53 fishes from all the experimental ponds. The use of locally processed formulated diet such as KLF is therefore recommended as a step in boosting the aquaculture sector.

The effects of four plant extracts on growth, sex reversal, immunological and haemato‐biochemical parameters in Nile tilapia,Oreochmomis niloticus(Linnaeus, 1758)

“…Variations in LWR for the same fish species in different studies have often been observed depending on season, population and environmental conditions (Froese, 2006). Wild Nile tilapia from Lake Naivasha, Kenya, and Kunduchi Ponds, Dar Es Salaam, Tanzania, also showed negative allometric growth as observed in the present study (Bwathondi & Abdulkarim, 2017; Otieno et al., 2014). Regression equations of LWR, in all treatment groups, showed higher values of the correlation of coefficient ( R 2 = 0.99), indicating a close relationship between length and weight (Alhassan et al., 2015).…”

EVALUATION OF POLYUNSATURATED FATTY ACIDS AND Β-Glucan CONTAINING DIET ON GROWTH PERFORMANCE AND CONDITION FACTOR OF PABDAH CATFISH, OMPOK PABDA (HAMILTON, 1822)

“…The length-weight relationship is widely accepted as an important tool in aquaculture in terms of growth performance, feed utilization, population dynamics, and stock management (Abdoli et al, 2008). Bwathondi & Abdulkarim (2017) found that the coefficient of determination (R 2 ) values in the CON and PBG groups with two different diets were 0.71 and 0.95, respectively of Oreochromis niloticus, while the PBG group significantly indicates good fitness. Datta et al (2013) observed that the length-weight logarithmic relationship between length and weight with regression equation coefficient 'b' varied between 2.7675 to 4.3922 with different supplemental diets during the experi-mental period.…”
