The focus on the ecology and diversity of the marine algae from Andhra Pradesh was

initiated by Sreemulu (1952 & 1953,) from the coastline of Visakhapatnam. A sum of 80 taxa
was recorded and published in “An annotated list of the marine algae of

Visakhapatnam” by Umamaheshwara Rao & Sreemulu (1970). Meanwhile, remarkable
annotations on the seasonal growth, phenology and spore shedding in red algae and brown

algae were detailed by several workers in different decades (Kaliaperumal & Chennubhotla,

2015).
Satya Rao & et al., (2011) premeditated the physico-chemical parameters of the seawater

and seasonal variations of 39 taxa of marine macroalgae from 75 quadrants sited in Bheemili

coast, Visakhapatnam. Srinivasa Rao (2012) focused on the distribution of seaweeds from the
saline habitats of Kakinada, East Godawari. Kaliaperumal & Chennubhotla (2015) reviewed

the distribution, diversity, resources, floristic & systematic data, ecology, biology,
environmental impacts, utilization and cultivation of marine algae of Andhra Pradesh.

Sowjanya & Sekhar (2015) accounted a comparative study of seaweed flora over a while
concerning climate change in Visakhapatnam Coast and documented the species

composition, vertical distribution and monthly variations of 48 taxa of marine macroalgae.

Bast & Rani (2019) has discovered the new species Ulva uniseriata based on phylogenetic
reconstruction using nrDNA ITS1 locus collected from the estuarine region of Pulicat Lake,

Nellore District.
The Indian coastline habitats are highly sensitive and susceptible to both natural

and anthropogenic threats that lead to the deterioration and extinction of seaweeds, which
cause the lessening of microorganisms in the population range. The major factors influencing

marine biodiversity are climate change about the biotic and abiotic components (Palanisamy

& Aron Santhosh Kumar, 2020). The investigation of Sowjanya & Sekhar (2015) clearly
validates the absence of 41 when compared to 1964 data obtained from this coast of Andhra

Pradesh.

Therefore, conservation of these unique habitats of the earth should be considered to
avoid its deterioration and managing our natural resources in a more sustainable way for

future prosperity. Conservation measurement on seaweeds is very limited; often for selective
genera for their commercial values in Tamil Nadu, Kerala and Gujarat. Places with the rich

diversity of seaweeds should be monitored with proper attention to protecting these natural
treasures from habitat destructions. Cultivation techniques such as the long-line rope method,
