Effect of Artemia on the Reduction of BOD Level of Distillery Effluent – A Short Communication
Abstract: AbstractEnvironmental pollution is one of the most important problems in this century and it’s mainly due to the increased industrialization. Industrial wastewater contains heavy pollutant and it should be treated before it is discharged into the environment. However, nowadays industries were not carrying out the treatment process properly due to the heavy cost of the treatment process. Nowadays, improperly treated effluent is rich in high BOD level and it causes …

Biodecolorization of Textile Dye Effluent by Biosorption on Plant Biomass and Equilibrium Modelling
Abstract: AbstractDye effluent discharge into water bodies leading to water pollution. Each textile dye process requires a different amount of dye and also it generates a different amount of effluents. Most of the physico-chemical methods are insufficient and highly expensive. Biosorption is an alternative technology for the treatment of different textile and other effluents. Aquatic plants specially water hyacinth showed a greater potential to use as biotrap for textile effluent treatment. …

An Assessment of Insect Diversity of Nal Sarovar Sanctuary (Ramsar Site), Gujarat, India
Abstract: A study was conducted on biodiversity of Nal Sarovar Sanctuary from July 2016 to March 2018 (2 years) using stratified sampling method, which was done seasonally from July 2016 to March 2018 using stratified random sampling method. Stratified random sampling was done in such a way that all the major habitats were covered. The insect diversity was explored through the Visual Encountered Survey (VES). During the survey, a total of …

Invasive Fish Species in India: Challenges, Threats and Impacts
Abstract: There are 31 invasive alien fish species introduced in India for aquaculture purposes, as well as over 600 varieties of ornamental aquarium fishes. Invasions of exotic freshwater fishes have had a negative impact on fish biodiversity. The estimated annual average production of alien species fit for human consumption amounts to approximately 18.2 to 34.5 percent of the annual average production of marketable fish cultures. Many more changes are expected as …

Pollen Biology and Stigma Receptivity in Nymphoides indica (L.) O. Kuntze (Menyanthaceae)
Abstract: AbstractNymphoides indica (L.) O. Kuntze an emergent aquatic plant of Menyanthaceae, commonly called ‘floating hearts” is bisexual, hypogynous and distylous (Two types of style – long style and short style) with 4 – 8 sepals and petals. Stamens correspond to the number of petals. The present study deals with phenology, pollen biology and stigma receptivity of N. indica. The pollen grains are yellow, medium, monad, triangular, heteropolar, radially symmetric, parasyncolpate …

Sodium benzoate induced reproductive and metabolic changes in Anabas testudineus (Bloch, 1792)
Abstract: AbstractSodium benzoate is an effective antimicrobial agent used as a food preservative, but recently gained attention as the chemical toxicant. The present study investigated sodium benzoate induced male reproductive toxicity and metabolic changes at100 mg/ L concentration in the freshwater fish, Anabas testudineus. Sodium benzoate did not alter the weight of fish but increased the secretion of mucous as the primary defensive mechanism. Reduction in the absolute and relative weights …
