The accelerated development of high-density brackishwater shrimp farming necessitates
the importance of bioremediation. Seaweeds have the potential to reduce nutrients from
aquaculture systems and provide extra income when species of economic importance are
used. Identification of suitable seaweed species which is locally available in abundance
with bioremediation capacity in brackishwater system is paramount, and the present study
addresses this issue. An exploratory monthly survey was undertaken in three
brackishwater systems in Chennai coast viz. Muttukadu lagoon, Vennangupattu Lake
and Pulicat Lake from March 2018 to February 2019 which led to a focus on species of
the family Gracilariaceae. Identification of the species through taxonomical and molecular
observations confirmed that seaweed from Muttukadu lagoon and Vennangupattu
Lake is Agarophyton tenuistipitatum and that from Pulicat Lake is Hydropuntia edulis.
Evaluation of the bioremediation potential of these two species indicated that they were
similar with respect to ammonia and phosphate reduction efficiency whereas the specific
growth rate of A. tenuistipitatum was significantly higher than H. edulis. Furthermore, the
nutrient reduction efficiency and specific growth rate was significantly higher at biomass
density of 3.5 and 4.5 g Lāˆ’1 compared to 1.5 and 2.5 g Lāˆ’1. It could therefore be
concluded that A. tenuistipitatum could be utilised for bioremediation as well as culture
in brackishwater system at a biomass density ranging from 3.5 to 4.5 g Lāˆ’1Not Available
