Seasonal incidence of macrophyte productivity at lower trophic level in two types of aquaculture ponds, Guwahati, AssamAuthor(s):
Parag Deka, MM GoswamiAbstract:
Seasonal prevalence of macrophytic productivity was studied in two perennial aquaculture ponds located at Gauhati University Campus, Guwahati, Assam, India. One of the experimental pond is manually managed (Pond A) with the application of lime and inorganic and organic fertilizer. The other is a naturally maintained pen culture pond (Pond B) recovered from a part of swamp without addition of lime and fertilizer. The reclaimed zone of natural pond is separated from the perennial swamp by bamboo screen. The present study exhibits 17 species of macrophytes belonging to 15 genera under 14 families. Besides Phragmites karka, a riparian element is found to dominate the surrounding non-recovered zone outside the pen culture system. The study reveals that 5 species belong to free-floating, 1 floating leaved emergent, 7 rooted emergent and 4 rooted submerged. The Pond A encounters with 11 species whereas Pond B with 12 species dominated by Eichhornia crassipes with higher biomass production in comparison to former. The macrophytic productivity of most of the species shows a summer-monsoon peak in both the studied ponds.Pages: 337-340 | 696 Views 7 DownloadsDownload Full Article:
