Objective: The objective of this study was to analyze the phytochemicals and prediction biological activities in petroleum ether extract marine green macro alga Codium decorticatum (Woodward) M. Howe (Green algae) collected from Mandapam, Tamil Nadu, India. Methods: characterization biochemical done by gas chromatography–mass spectroscopic (GC-MS) spectra analysis were analyzed using Prediction...

Optimal feeding is often constrained by predation avoidance, which may direct feeding to take place on more sheltered, but less profitable, parts of the habitat. Though constrained, feeding preferences and/or digestive capabilities should coevolve with the energetic and nutritional needs of the animal. These needs, as well as risk taking for these goals, may differ between the sexes. We studied...

Predator – prey interactions are often highly co-evolved, with selection over time for prey with morphological and behavioral traits that minimize predation risk. Consequently, in many environments prey choose among potential habitats according to their refuge value. It is unclear, however, when presented with new habitats, if prey are able to evaluate the predation risk of these relative to fa...

In Southeast Asian nations, cultured hybrid groupers are facing serious infestation by the marine parasitic leech Zeylanicobdella arugamensis (Annelida, Hirudinea). They attach to sucking and biting on surface of skin, paving way for secondary infection upon fish. The objective study is utilize locally available seaweed control leeches. methanol extracts brown alga Sargassum polycystum C. Agard...

Abstract This work aimed to introduce a new technique for improving sustainable biodiesel from Microchloropsis salina by examining the impact of various nitrogen sources, salt stress, and carbon enrichment, individually or in combination, determine best treatment conditions biomass lipid productivity as well quality. M. effectively utilizes nitrate (NaNO 3 KNO ) organic (especially yeast extrac...

The current study evaluated the effects of a methanol extract from Chaetomorpha aerea (a green alga) on non-specific immune responses and resistance against Edwardsiella tarda infection in Labeo rohita. Different doses (5, 50 500 mg/kg body weight) were injected into fish intraperitoneally while control group was with 0.2 mL sterile physiological salt solution. Variations several immunostimulat...

The article studies the experimental process of cultivation microalgae in a photobioreactor (PBR) to study effect technological conditions on productivity microalgae. This allows obtaining initial data for development closed cycles using energy potential alga mass heat and power supply various industries, including agricultural enterprises (livestock complexes, poultry farms, etc.) scheme cycle...

Studies on toxicities and tolerances of cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) in the brown alga Isochrysis galbana and in the green-lipped mussel Perna viridis were conducted by short-term bioassays using endpoints growth production and mortality, respectively. The 5-day EC(50) and 24-h LC(50) of these heavy metals were determined in the brown alga and mussel, respectively. The EC(...

Trebouxia aggregata (Archibald) Gärtner (phylum Chlorophyta, family Trebouxiaceae), a lichen symbiotic alga, has been identified as host of the well-known herbaceous plant virus Cauliflower mosaic virus (CaMV, family Caulimoviridae). The alga had been isolated from Xanthoria parietina more than 70 years ago and has been maintained in a collection since that time. The CaMV detected in this colle...
