| dc.description.abstract | A study was conducted to analysis the proximate composition of catfish eggs, collected from
cultured and wild sources of the same year class during the pre spawning and spawning
season from June 2018 to September 2018. The study incorporated five commonly available
catfish species, in Bangladesh including Shing (Heteropneustes fossilis), Magur (Clarius
batrachus), Pabda (Ompak pabda), Gulsha Tengra (Mystus bleekeri) and Tengra (Mystus
v
vittatus). The aim of the study was to analyze the proximate composition of catfish egg as
well as to know the compositional differences between the eggs of two different sources. A
total of thirty, fifteen fish sample from each sources were taken, while the cultured sample
were taken after the age determination of the wild samples. The egg samples were
categorized into two groups; wild and cultured and proximate compositions were analyzed
separately by following AOAC method for comparison between the two groups. The average
moisture, fat, ash and calcium content was 66.22%, 0.4326%, 2.44%, 0.290828%
correspondingly in wild sample, found to be higher, comparing to the cultured, where average
protein, phosphorus and energy content was 26.932%, 0.25248% and 454.67 kj/gm in
cultured sample higher than that of wild. Significant differences were found between the
values of wild and cultured sample. The proximate composition of fish egg also varies in two
same species taken from two different sources. This study also depicts that wild fish sample
accumulate more moisture, fat, ash and calcium than cultured sample, while the protein,
phosphorus and energy content is higher in cultured sample. This study can be helpful for
further research efforts on the compositional analysis of fish egg or gonad investigation of
catfish to know the impact of proximate composition on broodstock for production. This
study can also work as an access for future research work on the potential effects of
proximate composition on offspring. | en_US |
