Download or read book A Guide to Bycatch Reduction in Tropical Shrimp trawl Fisheries written by Steve Eayrs and published by Food & Agriculture Org.. This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch is the unwanted or non-target part of the catch taken by fishermen. It is either discarded at sea or used for human or animal consumption. The capture of bycatch may pose a threat to species diversity and ecosystem health because this part of the catch is usually unregulated. In tropical shrimp-trawl fisheries, bycatch often consists of juvenile food-fish species and is therefore a threat to food security and sustainable fisheries production. Bycatch is a global problem that must be addressed. This Guide to Bycatch Reduction in Tropical Shrimp-Trawl Fisheries is designed for fishermen, net makers, fishing technologists and others interested in a practical guide to the design, use and operation of effective bycatch reduction devices. Fishery managers, policy-makers and legislators will find this guide useful to help develop specifications governing the design and application of these devices in a shrimptrawl fishery. The issue of bycatch is not going away and scrutiny of fishing activity is increasing. All fishermen are strongly urged to use appropriate bycatch reduction measures to help maintain the productivity of the fishery and the long term prosperity of the fishing industry. By responding appropriately, fishermen can help to protect the marine environment and assist global food security both now and in the future. Also published in French and Spanish.

Download or read book Advances and best practices in bycatch reduction in tropical shrimp trawl fisheries written by Eayrs, S., Fuentevilla, C. and published by Food & Agriculture Org.. This book was released on 2021-10-25 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report describes efforts to mitigate bycatch through gear modifications and adaptations in the tropical shrimp-trawl fisheries of over 30 countries. It provides a summary of efforts by each country and then synthesizes them to identify and describe best practice. A best practice in bycatch reduction is the application or adoption of appropriate, recognized approaches to modifying fishing gear, with the objective of reducing bycatch to the greatest extent practicable. This information serves as a benchmark to identify countries that are taking appropriate steps to reduce bycatch and those that are not. It also provides context from which the outcomes of research on bycatch reduction can be evaluated and compared, including the identification of effective bycatch reduction devices, and serves to identify future research priorities. In the context of this report, best practice includes the installation and use of TEDs and BRDs that are optimally rigged and operated so as to reduce bycatch. It also includes the application of appropriate regulations to ensure effective performance, as well as the introduction of effective outreach and extension programmes to enhance and sustain best practice to reduce bycatch.

Book excerpt: Tropical Mariculture takes an in-depth look at developmental activities in a growing industry striving towards sustainability and environmental integrity. All of the contributors to this book have considerable experience and expertise in the field of tropical mariculture, and this is the first book to bring expert contributions together. The topics covered are wide and varied, ranging from general issues such as the impact of mariculture on coastal ecosystems to genetic improvement of cultured marine species, as well as the specifics of breeding selected marine species of current importance, such as groupers and sea bass. Significant coverage is also given to the problems of larval rearing in inland aquaculture as well as the demands of water- and land-based resources in a tropical environment. This book will be essential for everyone working in and researching tropical mariculture. Looks at developmental activities in tropical mariculture All of the contributors are experts in the field Covers specific breeding problems and larval rearing Studies the environmental impact of inland aquacultural activities Provides detailed examples of cultivated species in the tropics Compiles mariculture strategies and discusses example species First book to give an overview of tropical mariculture

Download or read book Commercial Fishery and Biology of the Fresh water Shrimp Macrobrachium in the Lower St Paul River Liberia 1952 53 written by George C. Miller (Zoologist) and published by . This book was released on 1971 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A small fishery was conducted for the large commercial fresh-water shrimp, Macrobrachium vollenhovenii, using traps. A second smaller species, M. macrobrachion, was culled from the trap catch for the fishermen's use. The estuarine fishery was seasonal (May to January) during the period of low salinity. Cost of raw tail meats to the consumer was over $1.00 (U.S.) per pound. The fishermen derived more than $7,500 from the fishery. Commercial shrimp, M. vollenhovenii, spawned in the estuary from May to January. Fecundity was estimated at 12,000 to 45,000 eggs per female. As the embryo developed the color of the egg changed from red to brown. Embryonic and larval development to time of setting of M. vollenhovenii was believed similar to that of M. rosenbergii, 50 to 65 days. An intensive push-net fishery was conducted by women on the zero age group soon after the juveniles had set. Juvenile shrimp were not caught by traps. Monthly length distributions indicated that the fishery was supported by age group one, which was replaced at the end of the season by age group zero. Age group zero grew rapidly and reached a modal length of 75 to 80 mm. in 9 months in January; and adults grew slowly and increased in length to 85 to 90 mm. in May, and 100 to 105 mm. in November. The weight-length relation of M. vollenhovenii ovigerous females was expressed by the equation Low W = --4.656603 + 3.011392 Log L, and males and nonovigerous females by Log W = --4.829560 + 3.092213 Log L. The characters used to distinguish M. macrobrachion from the commercial shrimp are given. The smaller species (modal length 50 to 54 mm.), constituted 88 percent of the shrimp discarded from the commercial catch. The trap fishery harvested the adults of the two species, which differed considerably in length, without harm to either species.

Download or read book Marine Ornamental Shrimp written by Ricardo Calado and published by John Wiley & Sons. This book was released on 2009-03-16 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine ornamental shrimp are amongst the most heavily traded invertebrate species in the aquarium industry. The majority of traded species are still collected from the wild, having a major effect on ocean ecosystems. An increase in the amount of culture of these species is now a major priority for those in the trade and for marine conservationists. Marine Ornamental Shrimp provides a global overview of the biology, culture and conservation of the major families of marine ornamental shrimp. Coverage in this thorough volume includes ecological aspects, reproductive biology, major techniques used in culture systems for maturation, larviculture, and juvenile growth, and details of the main conservation issues surrounding these important species including a discussion of the negative aspects of wild specimen collection and the ongoing efforts to mitigate such impacts. Marine Ornamental Shrimp is an important and extremely timely publication which will be an essential reference and manual for all those involved in the trade and culture of marine ornamental species, including aquaculture scientists and personnel in aquaria. Conservation biologists and invertebrate zoologists will also find much of importance within this book. Libraries in all universities and research establishments where aquaculture and biological sciences are studied and taught should have copies of this book on their shelves.
