The Impact

In this study, fish farmers’ management practices, occurrence, and knowledge of fish diseases in Nyeri County, Kenya, were evaluated. Fish farming management practices for small-scale farmers in Kenya have numerous challenges which have led to disease occurrence and reduced production. Moreover, the impact and association of these challenges to farmers’ knowledge of fish diseases and their burden has not been fully studied. A semistructured questionnaire was used to capture farmers’ biodata, fish species farmed, and farmers’ management practices such as handling of nets, pond fertilization, and disposal of fish waste. Farmers’ knowledge of fish diseases was based on their ability to identify independent and dependent variable indicators. Independent variables included clinical signs, decreased feeding, bulging eyes, floating on water, abdominal swelling, bulging eyes, abnormal skin color, reduced growth, and abnormal swimming with fish death as were the dependent variable. A total of 208 farmers were interviewed and included those of tilapia (134), mixed tilapia and catfish (40), catfish (22), rainbow trout, and five dams under cooperative management. Tilapia was the most kept fish species (66.8%) followed by polyculture of tilapia and catfish (20%) and rainbow trout (2%). Most respondents were male (78.5%) over 51 years of age (50%). Fifty percent of the respondents had secondary school education. There was a significant association between deaths and sharing of nets in Kieni East subcounty ( p = 0.0049 , chi-square), while on-farm fish waste disposing appeared to cause higher deaths compared to burning of the waste although not statistically significant ( p = 0.13 ). Few respondents observed decreased feed uptake (<20%) and poor growth. Fifty-seven percent of farmers reported mortalities. Fish poor growth, floating in water, and management practices in subcounties had significant effect on fish deaths. The farmers had knowledge of signs of diseased fish, but there was paucity of knowing the specific causes of disease. Farmers need to be empowered on best aquaculture husbandry to avoid disease transmission and specific fish disease signs to enhance proper reporting of disease for subsequent mitigation measures.

Abstract Poor starting nursery pigs are a common source of frustration for pork producers due to suboptimal lean tissue production and failure to thrive. This is generally a multifactorial issue with potential nutritional, infectious and management contributors. Commonly encountered respiratory and enteric pathogens include porcine reproductive and respiratory syndrome virus (PRRSV), influenza A virus (IAV), porcine enteric coronaviruses (TGEV/PEDV/PDCV), and group A, B, and C rotaviruses, as well as Salmonella typhimurium, enterotoxigenic Escherichia coli, Streptococcus suis, and Haemophilus parasuis. Infection with one or more of these agents can ultimately antagonize pig health and performance. However, while these specific pathogens may be causing an observed disease symptom, pigs may have been predisposed to infection due to various management, nutritional, and environmental risk factors. As many of these potential pathogens are endemic in production systems, it is important to remember that simply detecting a potential pathogen within a population is often not sufficient to assign cause for poor growth and production. To help fully interpret the impact of a detected agent, diagnostic efforts should focus on providing proof that the agent is actually causing disease. Molecular detection methods, such as PCR, are increasingly available for common pathogens and have high diagnostic sensitivity but lower diagnostic specificity. This paper will discuss the clinical signs and gross and microscopic lesions associated with common nursery pig pathogens, as well as proper sampling and diagnostic testing necessary to detect and confirm disease following infection with these agents.

The Impact

Three trends in industrial development contribute to the industrial history of West Bengal during the 1980–1991 period—the continuation of a secular decline in terms of employment and value added in manufacturing industries vis-à-vis other states, an ancillarization and flexibilization of production into small-scale factories with less than 20 workers, and a differential impact of this ancillarization on basic goods and consumer goods industries, with the former performing much better than the latter. Viewed through the theoretical lens of structural demand and agriculture–industry relations, the relatively slower growth of consumer goods industries poses a puzzle when the spectacular growth of agricultural output during the 1980s is considered. In this article, I suggest that tying together three factors—the impact of the ‘Green Revolution’ on West Bengal’s agriculture, the nature and effect of the Left Front’s land reforms, and the role of rural commercial capital—can in turn hold together three outcomes for the period 1980–1991 in a single explanation—high agricultural growth, mass poverty among the rural poor despite land reforms and agricultural growth, and the poor growth of consumer goods industries despite high agricultural growth.

The Impact

The objective of the research was to evaluate the impact of the fishing season on the value in use and physicochemical properties of the meat of selected fish species reared in Polish aquaculture. The study was conducted on five species: rainbow trout, common carp, grass carp, pike and tench. Fish were obtained from farms located in the Lublin Voivodeship in two seasons (spring/summer and autumn/winter). Morphometric measurements of the fish were performed, the percentage shares of body parts were assessed, and the physicochemical properties of the muscle tissue were measured: pH, electrical conductivity, water holding capacity, and CIE L*a*b* colour characteristics. The fishing season significantly affected the body weight of carp, rainbow trout and pike, the greatest body height of carp and rainbow trout, and the total length and head length of pike. Pike, grass carp and tench had significantly lower Fulton’s condition factors in the autumn/winter season than in the spring/summer season. The season significantly influenced the share of viscera in rainbow trout and grass carp, and that of fins in carp and rainbow trout. A significant impact of the season was also noted in the case of pH in rainbow trout and tench, electrical conductivity in trout, pike and tench, and the M/T ratio in grass carp and tench. Chromatic parameters differed significantly between seasons in pike (a*) and in carp and rainbow trout (b*).

The Impact

Mycoplasma hyopneumoniae is a very important pathogen which causes enzootic pneumonia (EP) affecting pig herds worldwide. M. hyopneumoniae establishes itself in the respiratory system causing pathological changes, and resultant pneumonic lesions can be detected at slaughter via lung examination, appearing as red to pink lesions which resolve over time, leaving scar tissue on the lobes. Mycoplasma spp. infection can be complicated by coinfections with other pathogens such as swine influenza virus (SIV) and porcine circovirus (PCV2). These coinfections result in worsening of clinical symptoms and lung lesions, therefore increasing the impact on performance of the affected animals. Therefore, it is important that focus is placed on improving overall respiratory health and managing overall herd health, rather than just solely focusing on M. hyopneumoniae. Management practices should be implemented to control the disease, which commonly involve vaccination to reduce the impacts of the disease. Effective vaccination is important, and can be ensured by correct vaccine handling, storage and administration. The vaccine used can also play a part in the success of the vaccination programme so this should also be assessed, which can be done via lung examination and noting of clinical signs and performance parameters. When vaccination is successful, the level of lung lesions should be reduced, performance improved and consistency between batches, demonstrating that respiratory health is more stable.

The Impact

The disposal of food waste is a current and pressing issue, urging novel solutions to implement sustainable waste management practices. Fish leftovers and their processing byproducts represent a significant portion of the original fish, and their disposal has a high environmental and economic impact. The utilization of waste as raw materials for the production of different classes of biofuels and high-value chemicals, a concept known as “biorefinery”, is gaining interest in a vision of circular economy and zero waste policies. In this context, an interesting route of valorization is the extraction of omega-3 fatty acids (ω-3 FAs) for nutraceutical application. These fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have received attention over the last decades due to their beneficial effects on human health. Their sustainable production is a key process for matching the increased market demand while reducing the pressure on marine ecosystems and lowering the impact of waste production. The high resale value of the products makes this waste a powerful tool that simultaneously protects the environment and benefits the global economy. This review aims to provide a complete overview of the sustainable exploitation of fish waste to recover ω-3 FAs for food supplement applications, covering composition, storage, and processing of the raw material.

Abstract The data requirements and resources needed to develop effective indicators of fishing impacts on target stocks may often be great, especially for mangrove fisheries where, for example, tidal cycles sequentially flood and drain the habitat as a result of natural processes. Here, we used underwater video systems to evaluate the impact of small-scale fisheries on mangrove fish assemblages at four levels of fishing pressure (low, medium, high, and no pressure). The lowest values of species richness and abundance were recorded in the areas fished most intensively. Conversely, the highest species richness and the occurrence of larger-bodied fish were recorded in areas of reduced fishing activity, which was surprisingly similar to the “no fishing” areas. The slopes of the community size spectra steepened in response to exploitation, while the relative abundance of medium-sized fish (16–25 cm) declined. Fishing for local or regional markets, rather than subsistence, also led to a decrease in the abundance of larger fish (&gt;41 cm). The marked response of population parameters to fishing pressure reflected the impact of unregulated small-scale fisheries on areas of mangroves. Fishery management practices that ignore contemporary changes in these environments are likely to overestimate long-term yields, leading to overfishing. Thus, size-based approaches to evaluating fishing pressure were suitable for detecting negative responses from the mangrove fish assemblages. A next step will be to integrate size- and species-based ecological approaches that provide mechanisms to address pronounced decreases in specific species as a more profitable indicator of fishing impacts on mangrove fish assemblages. This approach will allow the development of effective conservation and management strategies.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.
