TL;DR: The results revealed that the Excoecaria agallocha leaves have the potential to control the Aeromonas hydrophila diseases in marine ornamental fish, Amphiprion sebae.
Abstract: Present study was performed to validate the potential of mangrove, Excoecaria agallocha leaves against Aeromonas hydrophila isolated from infected marine ornamental fish, Amphiprion sebae. Infected ten fish samples were collected from the marine ornamental fish hatchery and the bacteria was isolated and identified as Aeromonas hydrophila. Antibiotic resistance characterization was performed with commercial antibiotics. In vitro antibacterial activity of methanol and acetone extract of Excoecaria agallocha and their minimum inhibitory concentration (MIC) were assessed. Healthy Amphiprion sebae when challenged with the Aeromonas hydrophila, resulted in the development of clinical signs, those observed in the hatchery. The methanol extract of Excoecaria agallocha leaf was administrated with live A. hydrophila, decreased the percentage of mortality in the experimental groups. The phytochemical screening of the extract showed the presence of alkaloids, phytosterols, fixed oils and fats, tannins, phenolic compounds, proteins, free amino acids, gums, mucilage, flavonoids and lignin. The results revealed that the Excoecaria agallocha leaves have the potential to control the Aeromonas hydrophila diseases in marine ornamental fish, Amphiprion sebae.

TL;DR: The study found that the difference in reflectance of mangroves at canopy level is not only influenced by the chlorophyll content of species but also by the prevailing environmental condition and background reflectances of soil and water as well.
Abstract: In the Muthupettai mangrove environment, spectral properties of six mangrove species viz. Avicennia marina, Aegiceras corniculatum, Excoecaria agallocha, Acanthus ilicifolius, Suaeda monoica and S. maritima was studied using Multi band Ground Truth Radiometer (Model-041). The study found that the chlorophyll concentration of different mangrove leaves varies between 0.05 and 0.36 mg g -1 , registering the minimum in S. maritima and maximum in E. agallocha. Interestingly species with higher chlorophyll concentration showed lower reflectance values alteast in the spectral bands 1 and 2. E. agallocha registered 0.36 mg g -1 of chlorophyll while it recorded only 2.18 and 2.43% reflectance where as S. maritima recorded 3.16 and 3.27% of reflectance in bands 1 and 2. This indicates chlorophyll concentration is one of major factors responsible in determining the reflectance pattern of the pant communities. The spectral properties of mangroves were largely differed with that of the water and soil samples collected from the same locations, these results favourd the utilization of remotely sensed data for depicting various water and soil quality parameters from that of mangrove species in the mangrove environment. This study also found that the difference in reflectance of mangroves at canopy level is not only influenced by the chlorophyll content of species but also by the prevailing environmental condition and background reflectance of soil and water as well

TL;DR: In this article, the structure and species distribution of mangrove, in the Channel Nagathana Kalava has been described, where the authors have found that Avicennia marina, Excoecaria agallocha, and Sonneratia apetala were found to be present on the banks of a major channel of the Godavari river running through the forest, and the area behind the belt consisting of Acanthus ilicifolius and Myriostachya wightiana is generally colonized by E. marina.
Abstract: Coringa mangrove forest is located in the Godavari delta, Andhra Pradesh, India. The mangrove community consisted of more than 13 species of mangrove and other plants in the present study area. The following three dominant mangrove plants, Avicennia marina, Excoecaria agallocha and Sonneratia apetala were found to be present on the banks of a major channel of the Godavari river running through the forest. The structure and species distribution of mangrove, in the Channel Nagathana Kalava has been described. The area behind the belt consisting of Acanthus ilicifolius and Myriostachya wightiana is generally colonized by E. agallocha and A. marina. The zone has been called the Avicennia and Excoecaria zone. Adjacent to this zone species like Aegiceras corniculatum and A. officinalis were the common species. In the flat clayey soil, Suaeda maritima was found to grow. In areas of high elevation, devoid of inundation of tidal seawater during the high tidal period, species such as M. wightiana and Acanthus were found to colonize both the banks of the channels.
