This book is the first to explore in detail the systematics and taxonomy of the digenean fauna of fish in Indian marine waters. It includes morphological descriptions of 648 species in 190 genera and 30 families. The figures from the original publications are enhanced and made more attractive. Each description is accompanied by information on hosts and distribution. Digenetic trematodes, usually known as Digeneans, are the most diverse group of metazoan parasites of marine fishes. They are parasitic flatworms (Phylum Platyhelminthes) with a complex life-cycle and as adults inhabit mainly the alimentary system and associated organs, but also occur in the blood, under the scales, in the body cavity and in the gall and urinary bladders. Keys to families, genera and species are provided, except for a few large and controversial genera, where morphological characters are insufficient for identification. Although there is extensive literature on Digeneans, it is scattered and largely in obscure local journals. Bringing together most of the primary literature on the subject, this book provides a primer for further study and a starting point for the use of modern molecular methods for the fauna of this region. Unique in its scope, it is a valuable resource for students, professional parasitologists and ecologists as well as fishery and wildlife biologists.

The Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater extraction are all contributing to the degradation of coastal environments. This book discusses aspects not covered in other books on the region, which largely focus on marine biodiversity, and examines several environmental challenges that are often ignored, but which have a significant impact on the environment. Evaluating the status quo, it also recommends conservation measures and examines the abiotic factors that play a major main role in the environmental changes. Lastly, the book addresses the biodiversity of the area, providing a general context for the conservation and management measures discussed.

The 2023 annual meeting of the ICES-FAO Working Group on Fishing Technology and Fish Behaviour (WGFTFB) and the International Symposium on “Innovations in Fishing Technologies for Sustainable and Resilient Fisheries” was held from 13 to 17 February 2023 in Kochi, India. [Author] The symposium was hosted by FAO in collaboration with the Department of Fisheries, Government of India, organized by the Bay of Bengal Programme Intergovernmental Organisation (BOBP-IGO) and National Fisheries Development Board (NFDB) in collaboration with Indian Council of Agricultural Research (ICAR) Fisheries Institutes and State Fisheries Universities. [Author] The symposium brought together 325 participants comprising of scientists, researchers, officials, policymakers, diplomats, industry, entrepreneurs, and students from 32 countries both online and offline delivering a total of 137 presentations providing a platform for discussions on the challenges facing world fisheries including depleted fish stocks, habitat destruction, pollution, climate change, fish loss and wastage bycatch, and ghost fishing. [Author] This report summarizes the symposium on “Innovations in Fishing Technologies for Sustainable and Resilient Fisheries” which comprised of eight thematic sessions: (i) active gears (ii) passive gears (iii)indicators (iv) abandoned, lost or otherwise discarded fishing gear (ALDFG) (v) survival/behaviour/physiology (vi) energy efficiency (vii) general topics and (viii) gear design.

This publication narrates the voyages of the iconic Norwegian research ship and documents marine research in the Western Indian Ocean, from early exploratory surveys to the current ecosystem surveys undertaken to support fisheries management. It provides a rare glimpse into the realities of conducting research at sea and evaluates the impact of the Nansen programme.
