Genomics in Aquaculture to Better Understand Species Biology and Accelerate Genetic Progress by José Manuel Yáñez,Ross Houston,Scott Newman Pdf

From a global perspective aquaculture is an activity related to food production with large potential for growth. Considering a continuously growing population, the efficiency and sustainability of this activity will be crucial to meet the needs of protein for human consumption in the near future. However, for continuous enhancement of the culture of both fish and shellfish there are still challenges to overcome, mostly related to the biology of the cultured species and their interaction with (increasingly changing) environmental factors. Examples of these challenges include early sexual maturation, feed meal replacement, immune response to infectious diseases and parasites, and temperature and salinity tolerance. Moreover, it is estimated that less than 10% of the total aquaculture production in the world is based on populations genetically improved by means of artificial selection. Thus, there is considerable room for implementing breeding schemes aimed at improving productive traits having significant economic impact. By far the most economically relevant trait is growth rate, which can be efficiently improved by conventional genetic selection (i.e. based on breeding values of selection candidates). However, there are other important traits that cannot be measured directly on selection candidates, such as resistance against infectious and parasitic agents and carcass quality traits (e.g. fillet yield and meat color). However, these traits can be more efficiently improved using molecular tools to assist breeding programs by means of marker-assisted selection, using a few markers explaining a high proportion of the trait variation, or genomic selection, using thousands of markers to estimate genomic breeding values. The development and implementation of new technologies applied to molecular biology and genomics, such as next-generation sequencing methods and high-throughput genotyping platforms, are allowing the rapid increase of availability of genomic resources in aquaculture species. These resources will provide powerful tools to the research community and will aid in the determination of the genetic factors involved in several biological aspects of aquaculture species. In this regard, it is important to establish discussion in terms of which strategies will be more efficient to solve the primary challenges that are affecting aquaculture systems around the world. The main objective of this Research Topic is to provide a forum to communicate recent research and implementation strategies in the use of genomics in aquaculture species with emphasis on (1) a better understanding of fish and shellfish biological processes having considerable impact on aquaculture systems; and (2) the efficient incorporation of molecular information into breeding programs to accelerate genetic progress of economically relevant traits.

Welfare and Stressors in Fish: Challenges Facing Aquaculture by Leonardo Julián Magnoni,Juan Antonio Martos-Sitcha,Patrick Prunet,Juan Miguel Mancera Pdf

Consumers, producers, stakeholders, governmental regulatory agencies and NGOs are becoming increasingly concerned with the conditions in which aquatic organisms are reared worldwide. High demand for fish for human consumption represents a challenge that has to be fulfilled by an ever-growing aquaculture production. In this scenario, animal care over the entire life and production cycle must be guaranteed while avoiding significant economic losses. As a result, research is needed to maximize yields and minimize adverse outcomes by optimizing rearing conditions while keeping in mind the welfare of cultured fish. In this Research Topic we will focus on relevant aspects related to fish response to both biotic and abiotic stressors as a means of improving their welfare, integrating both physiological and behavioral responses. In fish the adaptive responses to rearing may differ depending on several factors, including the characteristics of the stimuli and the intrinsic properties of the species or the selected line. If complete adaptation is missing, the application of single or multiple stimuli may result in a stress response. Stress responses have been linked to systemic adjustments which negatively impacts the immune system of fish, as well as their growth and reproductive performance. Therefore, one of the main interests of this Topic is to understand the allostatic responses of aquatic organisms to several stimuli/ factors that may be present during rearing. An additional focus of this Topic will be on conditions that may improve fish welfare by decreasing the stress response, such as implementing adequate swimming conditions. The focus of the Topic is to contribute to our present knowledge to better understand the physiological response of aquatic organisms, which is central to improving aquaculture practices. Emphasis will be placed on potentially existing interactions between physiological and endocrine pathways to build an overall stress response. Another aspect that will be considered in this Topic is how intraspecific variability may affect the stress response.

Selective Breeding in Aquaculture: an Introduction by Trygve Gjedrem,Matthew Baranski Pdf

The foundation of quantitative genetics theory was developed during the last century and facilitated many successful breeding programs for cultivated plants and t- restrial livestock. The results have been almost universally impressive, and today nearly all agricultural production utilises genetically improved seed and animals. The aquaculture industry can learn a great deal from these experiences, because the basic theory behind selective breeding is the same for all species. The ?rst published selection experiments in aquaculture started in 1920 s to improve disease resistance in ?sh, but it was not before the 1970 s that the ?rst family based breeding program was initiated for Atlantic salmon in Norway by AKVAFORSK. Unfortunately, the subsequent implementation of selective breeding on a wider scale in aquaculture has been slow, and despite the dramatic gains that have been demonstrated in a number of species, less than 10% of world aquaculture production is currently based on improved stocks. For the long-term sustainability of aquaculture production, there is an urgent need to develop and implement e- cient breeding programs for all species under commercial production. The ability for aquaculture to successfully meet the demands of an ever increasing human p- ulation, will rely on genetically improved stocks that utilise feed, water and land resources in an ef?cient way. Technological advances like genome sequences of aquaculture species, and advanced molecular methods means that there are new and exciting prospects for building on these well-established methods into the future.

Selection and Breeding Programs in Aquaculture by Trygve Gjedrem Pdf

Although aquaculture as a biological production system has a long history, systematic and efficient breeding programs to improve economically important traits in the farmed species have rarely been utilized until recently, except for salmonid species. This means that the majority of aquaculture production (more than 90 %) is based on genetically unimproved stocks. In farm animals the situation is vastly different: practically no terrestrial farm production is based on genetically unimproved and undomesticated populations. This difference between aquaculture and livestock production is in spite of the fact that the basic elements of breeding theory are the same for fish and shellfish as for farm animals. One possible reason for the difference is the complexity of reproductive biology in aquatic species, and special consideration needs to be taken in the design of breeding plans for these species. Since 1971 AKVAFORSK, has continuously carried out large scale breeding research projects with salmonid species, and during the latest 15 years also with a number of fresh water and marine species. Results from this work and the results from other institutions around the world have brought forward considerable knowledge, which make the development of efficient breeding programs feasible. The genetic improvement obtained in selection programs for fish and shellfish is remarkable and much higher than what has been achieved in terrestrial farm animals.
