Achieving sustainable aquaculture: Historical and current perspectives and future needs and challenges

Important operational changes that have gradually been assimilated and new approaches that are developing as part of the movement toward sustainable intensive aquaculture production systems are presented via historical, current, and future perspectives. Improved environmental and economic sustainability based on increased efficiency of production continues to be realized. As a result, aquaculture continues to reduce its carbon footprint through reduced greenhouse gas emissions. Reduced use of freshwater and land resources per unit of production, improved feed management practices as well as increased knowledge of nutrient requirements, effective feed ingredients and additives, domestication of species, and new farming practices are now being applied or evaluated. Successful expansion into culture of marine species, both off and on shore, offers the potential of substantial increases in sustainable intensive aquaculture production combined with integrative efforts to increase efficiency will principally contribute to satisfying the increasing global demand for protein and food security needs.

Modulation of nutrient digestibility and digestive enzyme activities in aquatic animals: The functional feed additives scenario

Considering the costs of feed costs (nearly 60% of production cost), nutrition, feeding and feed utilization are among the most important factors in commercial aquaculture. During the last decade, administration of functional feed additives has been practiced for enhancing nutrient digestibility and digestive enzyme activities of cultured fish and shellfish. Traditionally, antibiotics were used for boosting growth performance and nutrient digestibility in commercial aquaculture. However, emergence of resistance pathogens and possible risk to human health resulted in limitation or prohibition of prophylactic administration of antibiotics. Recently, there was increasing attentions towards dietary administration of functional feed additives that include probiotics, prebiotics and synbiotics for elevation of digestive enzyme activity and nutrient digestibility. The results of those studies revealed contradictory effects of different pro‐, pre‐ or synbiotics on various fish species. It seems that the effects are species specific and related to modulation of the intestinal microbiota. In view of this issue, the present review provides a comprehensive sight on the effects of different pro‐, pre‐ and synbiotics on digestive enzyme activity and nutrient digestibility in different species with special focus on the mode of action. In addition, the present review highlighted the gaps of existing knowledge as well as suggesting the subjects which needs additional studies.     

Biosecure Shrimp Feeds and Feeding Practices: Guidelines for Future Development

For the purposes of this paper, biosecure shrimp feeds and on‐farm feeding strategies refer to the “feed, whether live, fresh, or formulated, and the management of the feed on the farm, should not be an entry point of potential pathogens to the shrimp and/or to the culture system.” The paper reviews the different feeds commonly used for the production of farmed shrimp and discusses their potential risks from a disease perspective, including the use of live hatchery and nursery feeds, the use of live and/or fresh food organisms for the production of broodstock, and the use of dry formulated shrimp feeds for shrimp growout operations. In addition, the paper discusses the critical role played by feed‐processing techniques for the pasteurization and destruction of pathogens within shrimp feeds and the need for nutritionists to formulate feeds for optimal nutrition and health, and not just for optimal growth. The importance of the development and implementation of good on‐farm feed management practices by farmers is discussed, including the prohibition of the top‐dressing of pelleted feeds on farm by farmers with unapproved feed additives such as antibiotics. Finally, the paper discusses the responsibilities of farmers, feed manufacturers, and traders regarding the development and use of recommended biosecure shrimp feeds and feeding practices.     

饲料中添加速大肥及高稳胺对皇冠鱼生长及抗氧化能力的影响

为了解速大肥和高稳胺对皇冠鱼生长及抗氧化能力的影响,以皇冠鱼(Aequidens rivulatus)为试验对象,在其基础饲料中添加0.5%的速大肥和高稳胺,进行对照试验,投喂30 d后测定其生长情况及肝脏过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、丙二醛(MDA)的含量。结果表明,0.5%速大肥添加量对皇冠鱼的生长起促进作用,降低了饲料系数,增强了机体抗氧化能力。高稳胺对皇冠鱼的抗氧化能力有显著作用。投喂高稳胺饲料后机体SOD活性与MDA含量均有所提高,其对皇冠鱼的生长起增益效果。因此,速大肥和高稳胺可用作皇冠鱼饲料添加剂大幅提高皇冠鱼产量。
