“…This indicator helps identify countries that might be more vulnerable due to their own emissions or the emissions they are exposed to. Exposure variables consider temperature and precipitation because temperature and precipitation are critical climate variables that directly affect aquaculture productivity [18,19]. Rising temperatures can lead to the loss of suitable habitats for fish, reduced oxygen levels, increased disease prevalence, and altered reproductive cycles.…”

Climate change poses a significant threat to the aquaculture industry, impacting both the productivity and sustainability of this vital sector. This study focuses on the vulnerability of the top aquaculture producing nations to climate change and explores potential novel adaptation strategy. The vulnerability assessment considered various factors, including the exposure of aquaculture systems to climate change, Productivity of the industry, climate change initiators and the GDP of each nation surveyed. The study identifies the United Kingdom (UK) aquaculture as the most vulnerable and at risk of climate change impacts followed by the United States of America (USA) and Nigeria’s aquaculture. In terms of continents, Europe, Oceania, and Africa are identified as the most vulnerable regions, while America and Asia are considered the least vulnerable. The UK, with its extensive aquaculture operations and geographical exposure to climate change risks, faces significant challenges in adapting to changing conditions especially with the exit from European Union (Brexit). The USA, another major aquaculture producer, also faces vulnerability due to its diverse range of climatic conditions and coastal aquaculture operations. Nigeria, a prominent aquaculture producer in Africa, is highly vulnerable to climate change due to its dependence on freshwater aquaculture systems leading to low water usage in aquaculture despite vast marine water resource. Strict measures including novel adaptation measure such as the NanoSolar technique must be put in place in these countries in other to ensure that aquaculture production doesn’t decline and also to ensure that global food security is not put under pressure with the growing world population size.

“…Poor implementation of regulatory frameworks, including the Fish Hatchery Act 2010 and Rules 2011, absence of a certification scheme for hatcheries are the main reasons for unfair competition between unregistered hatcheries and brokers (Shikuku et al, 2021). Siddique et al (2022a) reported that climate change such as temperature fluctuation, erratic rainfall, and solar radiation is becoming a major concern of hatchery owners for the productivity of fish hatchery. Climate change due to geographical location of Bangladesh can impact the embryonic development and impair maturation and breeding performance of broodstock (Siddique et al, 2022b).…”

Fish seed are important for the growth of aquaculture in Bangladesh, but there are many challenges associated with supplying quality fish seed. This review evaluated the current level of production, issues and challenges that are affecting the production of fish seed in Bangladesh. The fish hatchery was found to be the major contributor in terms of fish seed production. Out of 671 metric tons of fish seed produced in 2020–2021, above 99% were from hatcheries. Freshwater finfish hatcheries have expanded over the last 30 yr, and are distributed throughout the country, but there is no commercial hatchery for coastal and marine water finfish species in the country. Shrimp and prawn hatcheries are concentrated in Cox's Bazar and the greater Jassore regions, respectively, while crab culture is entirely dependent on wild capture. Crablets are collected from nature, which has a devastating impact on biodiversity and wild stocks. The fish seed value chain is multidirectional and interlinked, and intermediaries dominate the supply chain. Disease outbreaks and indiscriminate use of chemicals are major concerns in fish seed production. Management strategies such as the introduction of certification, training programs, technology transfer, access to credit, and implementation of the law could improve the quality and productivity of fish seed in Bangladesh.

“…Variations in WT are one of the most important factors influencing the aquaculture industry, and considerable changes in WT (3-5 • C) are potentially harmful and have a negative impact on aquatic fish growth and reproduction [10][11][12][13][14]. In this manner, abrupt changes in temperature have been shown to influence the maturation and breeding performances of tilapia breeders [15]. For example, in warmer environments, fish tend to have a longer growing season and have a faster rate, but they also seem to have a shorter lifespan than they do in cool water [16].…”

Nile tilapia is a high-demand commodity in most developing countries including the Philippines, but its production is hampered by fluctuating water temperature (WT) and dissolved oxygen (DO) concentrations, which are mostly influenced by temperature warming. Net shading has been demonstrated to reduce pond temperature and increase the rate of spawning in cultured tilapia. The current study aimed to investigate the potential effects of shading on the water quality parameters, blood indices, and serum biochemical profiles of cultured Nile tilapia. Fish were collected from unshaded (control) and shaded (experimental) ponds in three breeding cycles. WT and DO concentrations were measured, while hematological and biochemical analyses were performed. The results showed that the average WT was considerably decreased in the shaded pond with no significant difference in the DO concentrations. Red blood cells, hemoglobin, and lymphocyte counts were significantly lower in fish raised in shaded ponds, although mean corpuscular volume and neutrophil counts were significantly higher. Likewise, Chole, TP, and Alb values were significantly affected by the interaction of cycle and shading setup. Cortisol, Glb, K+, Cl−, Mg2+, and TCa values showed significant differences and were only affected by the cycle. Similarly, AST and ALT values showed significant differences and were affected by both cycle and shading setup. Water quality parameters (WT and DO), hematological blood indices, and serum biochemical variables were correlated positively with each other. In brief, prior data imply that net shading can reduce WT in aquaculture ponds, reduce stress in Nile tilapia, and lessen the consequences of temperature warming on species production.
