Ornamental fish keeping and its propagation has been an interesting activity for many, which provide not only aesthetic pleasure but also financial openings. In Bangladesh, about 80 exotic fish species were found with their decorative value, but in most cases, aquarists and transporters get problem during their rearing and transportation due to having no knowledge on their feeding management technique appropriately. As exotic ornamental fishes have to transport at long distance without feeding condition, therefore stress becomes arise due to starvation and leads to weak and death. This book provides some general information on survival performance, weight loss and behaviour of some freshwater exotic ornamental fish species under starved condition in aquarium and also provides physico-chemistry data of aquarium water under that condition. This book would be beneficial for aquarists, transporters, researchers, and other people related to this subject.

The global population is increasing day by day andtherefore the demand for food is also increasing. Inmany counties, the majority of the rural people arepoor and rice farming is the single most importantlivelihood for them. Drought prone Barind area ofBangladesh is considered one of the low output zonein terms of agricultural production. Most of thefarmers of this area are dependent on irrigationwhich ultimately increases the cost of production inmanifolds. Integrated rice-fish farming can be a goodoption to ensure better production and income fromrice fields and thereby, to alleviate poverty of thepoor fish farmer. This book provides some generalinformation's on fish farming in irrigated rice fieldincluding- soil and water quality, production of riceand fish, economics and species suitability for thisregion. This book would be beneficial for farmers, researchers, extension workers and other peoplesrelated to this subject.

The main objective of aquaculture is to reach the aquaculture product to the consumer which is not possible without marketing system. It helps to give a good connection among fishermen, intermediaries and consumers. In Bangladesh, fish marketing operates under private enterprise in which rich traders play a dominant role and this system yields for the poor fishermen and farmers only a low price. Apart from price and weight, the poor fisherman suffers at the hands of monopolist suppliers of ice, nets, boats and other gears. The main problem affecting fish marketing in Bangladesh are poor transport, poor physical facilities and ignorance of the factors affecting fish quality. Fish marketing is very important for to meet the demand of animal protein, to balance our investment and profit, and sustainable management of fisheries. So, this book is based on fish marketing approaches, costs and margin at fish markets and landing center which are very important, realistic, informative and meaning. This book would be beneficial for the fishermen, local traders, personnel's of Government and Non-Government organizations, researchers, students and other peoples related to this subject.
