Book excerpt: Mud crab culture has relied until recently on juvenile stock captured from the natural environment. This practice puts undue pressure on natural stocks and causes concern about the sustainability of mud crab aquaculture. This text documents research carried out to combat such problems.

This book was released on 2015-04-22 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book details the research work and their results obtained on the feeding trails and the evaluation of efficacy of different types of feeds (fresh, processed and combinational natural diets and the formulated pellet diets)for the juveniles of the green mud crab Scylla serrata. The present book gives an attempt (1) to evaluate the efficacy of conventionally used feeds and to identify suitable conventional feed combinations for mud crab culture, (2) to elucidate the energy budget for juvenile mud crabs, (3) to estimate the dietary protein requirements and (4) to evaluate the efficacy of various lipid supplements in formulated diets of mud crab. The book is organized into eight chapters.

Book excerpt: In New Caledonia, there is the strong political will to diversify aquaculture which is mainly based on shrimp farming. In this context, mud crabs have been considered as a potential species for aquaculture development. One of the main constraints to develop crab farming is the availability of formulated feed. Thus, the main purpose of this thesis is to get information on the crab nutritional requirements in order to formulate a balanced diet. However, we had to clarify first how many species of mud crab were present in New-Caledonia. The result of our morphological and genetic investigations carried out on 63 specimens from 9 areas of the west and northeast coast of New-Caledonia confirmed that only one species, Scylla serrata, is commercialized in this country. Consequently, S. serrata was used in our nutritional study based on two experiments to: i) evaluate the soy protein concentrate (SPC) compared with the fishmeal as the main protein source and ii) determine the optimum level of SPC in the diet for molting and tissue growth. We observed two tissue growth phases within one molt cycle (MC): a fast tissue growth (FTG) occurred after ecdysis until early intermolt stage (30% of MC) which is followed by a slow tissue growth (STG) period from intermolt to ecdysis (70% of MC). Protein and lipid deposition followed the same trend than tissue growth while ash level increased quickly during five days after molt and then remained stable until the next molt. The two growth phases were correlated with the voluntary feed intakes (VFI) which was maximum during 2 weeks after ecdysis and then decreased by 50% over the five following weeks to reach a baseline until the next molt. Intake energy was allocated mainly for growth during FTG period and for maintenance during STG period. During STG, 28% of the ingested energy was accumulated for the next ecdysis. Replacement of fishmeal by SPC as main protein source did not affect tissue growth, efficiency of feed utilization and energy budget of crabs whatever the tissue growth period considered. The dietary SPC inclusion of 42% in the diet promoted growth (molt frequency and tissue growth), feed efficiency and retention of energy, protein and lipid. Hypothesis related to ammonia toxicity from catabolism of proteins in excess or anti-nutritional factors from soybean could explain the negative effects of higher inclusion of SPC in the diet for juvenile crabs. In conclusion, our work brings novel information on tissue growth, energy budget during a molt cycle and the ability of juvenile crab to use SPC as a main source of protein. On this basis we suggest to formulate nutritionally balanced diet without fishmeal to farm juvenile mud crabs S. serrata.

This book was released on 2023-04-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: India is bestowed with a long coastal line of over 8,129 km, two million sq. Km of Exclusive Economic Zone with 1.2 million hectors of brackish water bodies (Marine and Earth Sciences Group, 2009). Before 1960's, the markets of Indian Marine Products were dominated by dried items and were exported largely to neighbouring countries like Srilanka, Myanmar, Singapore etc., The quality of dried fish never receives much attention (Gupta and Samueal, 1985) due to improper handling while processing, storage, transporting and marketing. This situation gradually changed after the development of number of techniques such as canning, freezing etc. As a result, the major seafood importers from our country are Japan, USA, Europe, Middle East, Australia etc. India exports more than Rs. 8000 crores worth of seafood every year. The South East Asia is the largest importer of seafood from India with a major share (25.75%) followed by European Union (22.02%), US (19.17%), Japan (14.09%), China (7.06%), the Middle East (4.39%) and other countries (7.51%), (FISHING CHIMES, 2012).
Download or read book Mud Crab Aquaculture written by Colin Charles Shelley and published by Fao Inter-Departmental Working Group. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are four species of mud crab, Scylla serrata, S. tranquebarica, S. paramamosain and S. olivacea that are the focus of both commercial fisheries and aquaculture production throughout their distribution. They are among the most valuable crab species in the world, with the bulk of their commercial production sent live to market. This is the first FAO aquaculture manual on this genus, covering everything from its basic biology and aquaculture production, through to stock packaging and being ready to go to market. Information on mud crab biology, hatchery and nursery technology, grow-out systems, disease control, processing and packaging has been collated in this manual to provide a holistic approach to mud crab aquaculture production. Compared with other types of aquaculture, mud crab culture still has a large number of variants, including: the use of seedstock collected from the wild, as well as produced from a hatchery; farming systems that range from very extensive to intensive, monoculture to polyculture; and farm sites that vary from mangrove forests to well-constructed aquaculture ponds or fattening cages. As such, there is no one way to farm mud crabs, but techniques, technologies and principles have been developed that can be adapted to meet the specific needs of farmers and governments wishing to develop mud crab aquaculture businesses. Each of the four species of Scylla has subtly different biology, which equates to variations in optimal aquaculture production techniques. Where known and documented, variants have been identified, where not, farmers, researchers and extension officers alike may have to adapt results from other species to their mud crab species of choice and local climatic variables. Compared with many other species that are the subject of industrial scale aquaculture, mud crabs can still be considered to be at an early stage of development, as the use of formulated feeds for them is still in its infancy and little work has yet been undertaken to improve stock performance through breeding programmes.
