The Role of Veterinary Education in Fostering Aquaculture Development
No full textAbstractAquaculture is one of the most promising food producing industries, from both socio-economic and food security perspectives. It is developing fast and, unless there is a well thought-out strategy aimed at supporting this trend, errors can be made when dealing with aquatic animal disease outbreaks. Apart from establishing legislation and policies to assist countries/regions in implementing biosecurity measures, the strategy should focus also upon fostering adequate veterinary education, so that the “day-one” graduate to have a reliable level of understanding of/performance in the aquaculture sector. Veterinary schools, particularly those within countries which rely upon aquaculture as one of the national food producing industries, should be encouraged to include aquatic veterinary disciplines within their curriculum. Through special designed veterinary curriculums, there would be available more veterinarians specialised on aquaculture to serve the needs of stakeholders and to help ensuring regional food security
Study on Identification of Selection Indices for a Single Character to Increase Meat Production in a Population of Ropsa Carp
No full textAbstractIn the context of ensuring bio resources for future generations, scientific research of carp culture have shown that it can realize high meat production, if it respects certain conditions of race performance and the growth medium. The genetic improvement objective is to increase meat production, based on maximizing meat production per female of breeding stock. Estimation of genetic progress using the character selection requires the use of selection indices. The study consists in identifications of the selection indices of some morphological traits which can lead to maximizing the meat production in a population of Ropsa carp. In the structure of selection index was measured the characters on live animal: weight (W), body depth (BD) and standard length (SL). The biologic material was represented by 50 individuals of Ropsa carp from 5 families, each family consisting of a mother and two fathers. Individuals were reared intensively in the same environmental conditions, since juvenile stage until the age of three summers. For each selection index was determined line vector of partial regression coefficients and the hierarchy was based on the accuracy of genetic evaluation and genetic progress provided by each variant. After calculating indices for each character considered, it was found that selection to maximize meat production of Ropsa carp population can be done on the basis of selection for live weight character (selection accuracy is 52.22%). This provides a genetic gain of 60.6318 grams for live weight. By transformation of morphological traits of individuals in the population of cyprinids can increase the quantity of meat/individual and contribute to sustainable aquaculture development and traceability
An Integrative Approach to Healthy Social-Ecological System to Support Increased Resilience of Resource Management in Food-Producing Systems
No full textThe study addresses health-associated risks and health indicators required for the framing of Social-Ecological System Health (SESH) in aquaculture food-producing systems. The advantages of using a healthy Social-Ecological System (SES) are highlighted, to aid in the development of a new ecological system fostering the sustainability of aquatic ecosystems. The study used statistic modelling of some human infections with Cryptosporidium spp. and Cyclospora spp., used to obtain an estimate of the costs of zoonoses to health systems, and the outcomes of an epidemiological study involving the Eustrongylides spp. in fish. The study indicated that parasitic zoonoses have an important economic impact on health systems, environment and society at large. Holistic approaches to health, addressing all relevant actors are required to mitigate these impacts. To address the risk of eustrongylides and other fish-, and water-borne zoonoses, the development of new social-ecological system health should be constructed. For aquaculture production, such systems must include a biosecurity plan co-developed and negotiated by all relevant stakeholders. While the system’s feasibility is yet to be validated, regular revision of such systems’ functioning and outputs is an important premise to make them operational
Agroecological Approaches in the Context of Innovation Hubs
No full textAgroecology is a sustainable alternative to agricultural science, aiming at balancing the environment-plant-animal-man complex in an equitable way. Different players in the food system across the world are engaging in the practice and promotion of agroecology. Their experience serves as input for agroecology innovation hubs, thus assisting and accelerating the adoption of agroecological practices. Based on existing experience in implementation of innovation ecosystems and living labs in Romania, the study discusses critical factors required for a successful transformation of agriculture, with the aim to fill existing research gaps on agroecological techniques. The authors are also emphasizing the role of new business models in this area. The study used an anonymous survey with Likert scale ratings, and structural equation modeling, PLS. The study results were indicative of a certain degree of enthusiasm for agroecological practice adoption, particularly among organic farmers and business owners. The chances that these practices are adopted by farmers can be enhanced provided there is a systematic exchange of knowledge among the farmers. Clusters of farmers based on community of practice could create innovation ecosystems providing this accelerates its adoption. Correlation with the economic and political processes of the country is necessary, as emphasized by the farmers interviewed during the study. Through innovation hubs, agroecology must move from the currently smaller scale to larger scale practices such as agroecosystems and agri-food systems. These forms of organization should also take due account of relevant socio-economic, cultural, and political factors
