Aquaculture, an important source of food supply, is expected to be the main sector satisfy growing seafood demand in future. Being most diversified product world, aquaculture diversification can add resilience global security, consumer preferences, and promote price stability. Understanding relationships between production their causations crucial for developing effective strategies support long-term sustainability development. This study investigates direction causal using a panel vector autoregression (PVAR) model with three decades data Effective Number Species (ENS) values by country. Diversification measured terms within-group diversity (ENSα) between-group (ENSβ); this approach provides deeper insights into strategies. The results show that more conducive expansion globally, especially Americas Asia, positive effects are long lasting. Within-group also induces Europe and, lesser extent, Asia. Therefore, policies market incentives across different species groups within same group potential expand production. Other findings include leading Asia Europe, but not Africa. A possible explanation would accumulate experience, develop scope economies emerging technologies, build up capacities. These factors generate spillover facilitate diversification, considering have longer history development compared However, no significant relationship found diversification.

Agricultural production is under threat due to climate change in food insecure regions, especially Asian countries. Various climate-driven extremes, i.e., drought, heat waves, erratic and intense rainfall patterns, storms, floods, emerging insect pests have adversely affected the livelihood of farmers. Future climatic predictions showed a significant increase temperature, with higher intensity while variability exists patterns for extremes prediction. For mid-century (2040-2069), it projected that there will be rise 2.8°C maximum temperature 2.2°C minimum Pakistan. To respond adverse effects scenarios, need optimize climate-smart resilient agricultural practices technology sustainable productivity. Therefore, case study was carried out quantify on rice wheat crops develop adaptation strategies rice-wheat cropping system during (2040-2069) as these two contributions production. quantification impacts farmer fields, multidisciplinary approach consisted five models (GCMs), crop (DSSAT APSIM) an economic model [Trade-off Analysis, Minimum Data Model Approach (TOAMD)] used this study. DSSAT predicted would yield reduction 15.2% 14.1% APSIM 17.2% 12% wheat.

Abstract Global aquaculture production has grown very rapidly in recent decades. This is largely due to a number of innovations that increased the control with process and competitiveness. These come forms from radical new concepts knowledge adaption terrestrial food system. While there exist studies investigating impact specific innovations, are few take larger perspective on how over time impacts an industry or innovation system support these innovations. In this paper we review Norwegian salmon its infancy 1970 until present. Of particular interest increasing complexity industry, most conducted by suppliers not producers themselves. The insights also general global as among species advanced technologies, but where adapted other different systems.

Aquaculture has been the primary engine driving increases in global aquatic food supply for over three decades. Despite its undisputed success terms of increased production, there considerable concern and criticism regarding various aspects aquaculture, particularly relation to environmental social sustainability. However, no method developed or data collected, that can be consistently used compare aquaculture system performance along pillars sustainability: environmental, economic, performance, at finer scales. The Performance Indicators (APIs) are designed address this major gap. APIs adopt a very similar framework successful Fishery (FPIs) comparable with FPIs, more aggregated levels. This work introduces API approach implementation date. Thus far, 69 assessments have conducted associated 40% production quantity 36% value.

The largest companies in salmon aquaculture are rapidly getting bigger due to organic growth as well mergers and acquisitions, the now multi-national companies. There two main explanations for this growth: 1) An attempt become large enough exploit market power, or 2) Size is necessary adopt new technologies that increase efficient scale. In paper, we investigate degree of concentration each producer countries Atlantic salmon, globally all farmed account global nature using Herfindahl-Hirschman Indexes. results indicate a high smaller nations but not Chile Norway. Globally, industry can be characterized unconcentrated, it becomes even more so when supply other wild accounted for. Hence, motivation increased company size appears capacity knowledge technology.

Blue foods are highly diverse and supported by a wide range of ecosystems, production practices, markets. This diversity influences resiliency aquatic food systems, their capacity to contribute global security, the spread knowledge adoption innovations. Here, trends in determinants capture fisheries aquaculture were examined at country level. Results show that is more than production, social economic factors appear be as important for species biophysical factors. The diminished when governance weak, this poses challenges managing nutrition-sensitive production. It also illustrates greater potential address related access given less created economies scale making accessible among lower income groups.

Seaweed, also known as macroalgae, represents a vast resource that can be categorized into three taxonomic groups: Rhodophyta (red), Chlorophyta (green), and Phaeophyceae (brown). They are good source of essential nutrients such proteins, minerals, vitamins, omega-3 fatty acids. Seaweed contains wide range functional metabolites, including polyphenols, polysaccharides, pigments. This study comprehensively discusses seaweed seaweed-derived metabolites their potential feed ingredient in aquafeed for aquaculture production. Past research has discussed the nutritional role promoting growth performance fish, but effects on immune response gut health fish have received considerably less attention published literature. Existing research, however, demonstrated dietary seaweed-based metabolite supplementation positively impact antioxidant status, disease resistance, stress fish. Additionally, promote beneficial bacteria inhibit proliferation harmful bacteria, thereby improving nutrient absorption Nevertheless, an important balance remains between inclusion level resultant metabolic alteration review highlights current state knowledge associated importance continued endeavors regarding modulators growth, response, microbiota composition
