Abstract

The research was funded by National Agricultural Research Organisation (NARO) of Uganda. Abstract Hatchability of Artemia strains; Artemia franciscana from Great Salt Lake (GSL), A. franciscana from salt ponds in Vin Chao (VC), Chinese strain (Chinese), TUZ Parthenogetic Artemia from Kazakhstan (TUZ) and Parthenogenetic Artemia strain from Siberia (PAS) was examined using waters from lakes Katwe, Mururmuri, Bunyampaka, Bagusa and Maseche. The study purpose was to identify the best performing Artemia strain as well as the best suited saline crater lakes in Western Uganda for Artemia production based on hatchability. Artemia cysts were hatched under conditions described by Van Stappen (1996) in fabricated Artemia hatching cones at a salinity of 40ppm, temperature of 27±2°C, and light of 2000lux. Hatchability was monitored after 24hour and 48hour of incubation. Artemia franciscana (VC) had significantly higher hatching percentage than all tested strains (P-value <0.05). Lakes Katwe, Bunyampaka and Maseche waters presented the highest hatching percentages therefore are best suited for Artemia production.

Highlights

Artemia is commonly referred to as a brine shrimp belonging to the genus Artemia (Wurtsbaugh and Gliwicz 2001) and order Anostraca (Ben Naceur, Jenhani et al 2012)
Uganda being endowed with a number of hyersaline lakes which are reported habitats www.iiste.org for Artemia (Ben Naceur, Jenhani et al 2012; Gajardo and Beardmore 2012), exploration of possibilities for production of local Artemia resources can be one way of availing cheap affordable Artemia resources to Ugandan hatcheries
There was no significant difference in the hatching percentages of Artemia franciscana from the Great Salt Lake (GSL) and Chinese Artemia strain when tested in the different collected water samples

Summary

Introduction

Artemia is commonly referred to as a brine shrimp belonging to the genus Artemia (Wurtsbaugh and Gliwicz 2001) and order Anostraca (Ben Naceur, Jenhani et al 2012) They are micro crustaceans reported to inhabit extremely saline water environments including inland water bodies and coastal solar salt works (Gajardo and Beardmore 2012; Ogello, Kembenya et al 2014; Sui, Deng et al 2014). The use of these micro crustaceans as an important larval food for fish dates way back from the 1930s (Bengtson, Leger et al 1991). In a drive towards exploring possibilities for production of local Artemia resources, several saline crater lakes have been surveyed with no local Artemia resources so far been found (Nkambo, Bugenyi et al 2015a)
