Fishes are the most abundant vertebrate on earth. They are one of the most ancient, diverse and unique fauna. Not only are they a great source of income generation and economic returns but also a delicious food option having good protein value. They are very sensitive to any changes in the habitat and reflect it back. Global quandaries of the world include climate change and pollution and the fishes are no less affected. The bearings of stress on fish make it an effective tool for pollution and biomonitoring studies. How the fishes respond to stressors is critically variable and requires exhaustive experimental research at physiological and molecular level. Molecular biological research and study of stress physiology in fishes is gaining a quick momentum in light of unabated population ebullition. Fishes can thrive in diverse habitats and extreme climatic regime. Proper fish management at commercial level requires that the stress physiology of fish be fathomed and fish genetics be comprehended. These areas of research make us visualize the improvement of fish genes which will consequently improve the fish quality as food. In order to feed millions, man has to depend upon fishes as alternate source of food and therefore, fishery biologists are focusing their thrust area of research in these fields. We hope that the research articles deliberated in these ISCA 2019 proceedings will be of immense interest to the fishery biologists, molecular biologists, geneticists, aquaculturists and last but not the least, young and dynamic researchers and fish enthusiasts.

The aquatic ecosystems such as lakes, ponds, rivers, wetlands, reservoirs, estuaries and oceans along with their disparate flora and fauna form a splendid synthesis of a unique life. They together are instrumental in sustaining the life on earth. Their role in regulating the biosphere cannot be disregarded. The abundance and variety of life in the various aquatic habitats enriches the biodiversity in general and looks after the well being of life residing on land in particular. Water is without doubt the elixir of life but with the inevitable anthropogenic influence, it is undergoing depletion and deterioration. The aquatic biodiversity is very crucial in providing us the food, atmospheric oxygen, running the biogeochemical cycles, redeemer in food shortage and protection against the global climate change. The research articles, reviews and case studies on the plankton, benthos, fish reproductive physiology, seasonal variations, water quality, sediment quality, abiotic parameters presented in these ISCA proceedings 2019 focuses on the qualitative and quantitative maintenance of not only the aquatic ecosystems but also the indispensable animal and plant life residing in it. Conserving and maintaining our aquatic ecosystems will go a long way in not only providing us the food, clean water, jobs, economy and tourism enhancement but also save us from climate change, floods, earthquakes and other cataclysms. The collection of edited papers in this book will be of immense value to the young researchers in particular and academicians, science enthusiasts and student community in general.

The proportion of Reached to Unreached tilts heavily towards the latter in our country. In spite of the fact that we have achieved great strides of innovativeness in space, digital and agricultural technology, the population under the poverty line is still alarmingly high. There are plans and programms designed and launched to promote inclusive development. Obviously the effort is not adequate. Abdul Kalams dream of PURA is still unfulfilled. It is time we rise to the occasion. The book that is being conceived to be brought out addresses the issue to usher in sustainable development for the wellbeing of the society both urban and rural through application of advances in Life Sciences, Animal, Veterinary and Fisheries sciences in particular. The editors need to be complimented for putting together a bunch of articles in diverse fields of life sciences with a common goal of health of the society. The articles ranging from antimicrobials, antivirals, fish and dairy management, rodent control, mosquito control, biodiversity including invasive alien species and their impact. The book is good for teachers, researchers and students equally. The whole effort supports the concept of unity in Diversity. The article on obesity in students is a warning bell to youth to think in terms of yoga and other health practices in order to be able to live up to the adage Healthy body houses a Healthy mind.
