Alternative sources of fish oil(FO)are one of the major problems in aquaculture;therefore,the goal of the present study was to examine insect(black soldier fly larvae)oil(BSLO)as a potential replacer of fish/s oy oil in juvenile rainbow trout(initial average weight of 32±0.15 g)*** diets were formulated wherein FO(control diet)was completely replaced with either soybean oil(SO)or BSLO,and an additional BSLO-based diet supplemented with 1.5%bile acid(BSLO+BA)were fed to the fish for 10 *** performance of the BSLO fed group was similar(P>0.05)to that of the FO and SO fed groups,howeve r,the fish fed BSLO+BA diet registered the lowest growth(P0.05)affect the major nutrient content of whole-body,however,the fatty acid composition of the muscle and liver was influenced(P<0.05),with the highest 14:0,16:0,and total saturated fatty acid detected in BSLO or BSLO+BA fed trout compared to the others(P<0.001).No significant diffe rences were observed in eicosapentaenoic acid+docosahexaenoic acid(EPA+DHA)or total n-3 polyunsaturated fatty acid(PUFA)content in muscle among the groups,whereas,the highest EPA:DHA and n-3:n-6 ratios were detected in the FO *** expression for fatty acid binding protein(fabp),fatty acid synthase(fas),and△5 desaturase in the liver was lower in FO(P<0.05),while BSLO+BA registered the highest△6 expression(P=0.006).Supplementation of BA in the BSLO diet increased superoxide dismutase(SOD)and catalase(CAT)activities compared to the other groups(P<0.05).In conclusion,BSLO could serve as a substitute for FO and SO in rainbow trout diet without negatively impacting growth performance,whole-body composition and nutrient retention,and modulate the expression of fatty acid metabolism-related genes in rainbow trout.

In the Peninsular Malaysia and Northern Borneo island of Malaysia, various rich indigenous leafy vegetables and fruits grow and contribute to the nutritional and dietary values of the population. They have high water contents, thus, naturally vulnerable to rapid food spoilage. Food preservation and processing play a vital role in the inhibition of food pathogens in fruits and vegetables that are prevalent in Malaysia. Lactic acid fermentation is generally a local-based bioprocess, among the oldest form and well-known for food-processing techniques among indigenous people there. The long shelf life of fermented vegetables and fruits improves their nutritional values and antioxidant potentials. Fermented leaves and vegetables can be utilized as a potential source of probiotics as they are host for several lactic acid bacteria such as Lactobacillus confusus, Weissella paramesenteroides, Enterococcus faecalis, Lactobacillus plantarum, Lactobacillus buchneri, Lactobacillus paracasei, Lactobacillus pentosus, Pediococcus acidilactici, Pediococcus pentosaceus and Leuconostoc mesenteroides. These strains may be more viable in metabolic systems whereby they can contribute to a substantial increase in essential biologically active element than industrial starter cultures. This review is aimed to address some essential fermented fruits and vegetables in Malaysia and their remarkable reputations as a potential sources of natural probiotics.

A 45-day experiment was carried out to evaluate the growth performance, digestive enzymes activity and biochemical response of Cirrhinus mrigala fed graded levels of oil. Three isonitrogenous purified diets （6%, 8% and 10% of oil） were formulated. A total of 108 juveniles of Cirrhinus mrigala （5.95±0.25） g were equally distributed in triplicate groups in nine plastic tanks of 100 L capacity and fed under natural light cycle. Growth performance of the fish significantly reflected the effect of inclusion levels of oil tested but the diet with 8% lipid had the best significant growth performance [% weight gain, Feed Conversion Ratio （FCR） and Specific Growth Rate （SGR）], across different experimental groups. Levels of secretion of digestive enzymes in the fish fed different experimental diets resulted in significant values of （p〈0.05） amylase and lipase, while Aspartate transaminase （AST）, Alanine transaminase （ALT）, Lactate dehydrogenase （LDH） and Malate dehydrognnase （MDH） values in the muscle and liver decreased significantly （F〈0.05） as the levels of oii in the diet increased. However, serum biochemical parameters did not record any significant difference 6o〉0.05） with the exception of the total lipid across diets. The study confirmed the inclusion effect of graded levels ofoil in juvenile Mrigal diet, but the inclusion should not be more than 8% to avert growth depression.

Geostatistical evaluation of spatial variability of land subsidence rates in Lagos, Nigeria

引用

Geodesy and Geodynamics 2020年第5期11卷 316-327页

Accurate land subsidence prediction is fundamental for effective management of land subsidence and other associated geohazards. Lagos, the most densely populated city in Nigeria, has been adversely affected by widespread land subsidence. Previous studies have largely been restricted to analyzing space geodetic technique data. Unfortunately, this technique imposes spatial limitations resulting in incomplete coverage of the study areas due to atmospheric effects, orbital satellite characteristics, or surface characteristics. The application of geostatistics to georeferenced data obtained from space-based measurements can reliably provide complete information on spatial variability. The objective of this study is to provide an overview of current subsidence rates and to assess the spatial variability of land subsidence in the study area by using geostatistics that integrate semivariogram and ordinary kriging. The study area was partitioned into eight subregions;for each subregion, the experimental variogram was determined from the observed data and fitted to the optimal models. Seven subregions were fitted to exponential models and one was fitted to the spherical model. The model semivariograms were used in the kriging analysis to estimate the spatial variability of subsidence rates. The results showed that the nugget-to-sill ratio lies between 44 and 70%, indicating that the spatial variation of subsidence rates at the scale under study is moderately distributed and the mechanism of deformation is similar. The nugget effect of the subsidence rate is between 0.25 and 0.75, indicating that subsidence rates are influenced by various contributions. The predicted spatial variability of subsidence rates by Ordinary Kriging presents reliable values of R-squared(0.32 e0.42) and RMSE(0.21 e0.30). Critical subsidence rates characterised the areas around the Atlantic Ocean coastal alluvium deposit, the Lagos lagoon, and the Ogun River flood *** study successfully demon

Harvest and Postharvest Factors Affecting Bruise Damage of Fresh Fruits

Horticultural Plant journal 2020年第1期6卷 1-13页

作者： Zaharan Hussein Olaniyi Afawole Umezuruike Linus Opara Postharvest Technology Research Laboratory South African Research Chair in Postharvest TechnologyDepartment of Food ScienceFaculty of AgriSciencesStellenbosch UniversityStellenbosch 7602South Africa Postharvest Technology Research Laboratory South African Research Chair in Postharvest TechnologyDepartment of Horticultural ScienceFaculty of AgriSciencesStellenbosch UniversityStellenbosch 7602South Africa

Fresh fruits are susceptible to bruising, a common type of mechanical damage during harvest and at all stages of postharvest handling. In quest of developing and adoption of strategies to reduce bruise damage, it is of utmost importance to understand major factors influencing bruise susceptibility of fresh produce at these stages. This review presents a critical discussion of factors affecting bruising during harvest and postharvest handling of fresh fruits. Excessive compression forces during harvesting by handpicking or machines, and a series of impacts during harvesting, transport and packhouse operations can cause severe bruise damage. The review has further revealed that bruising is dependent on a number of other factors such as produce maturity, ripening, harvest time(during the day or season) and time lapse after harvest. The susceptibility to bruising is partly dependent on how these factors alter the produce physiological and biochemical properties, and the environmental conditions such as temperature, humidity and several other postharvest treatments. Hence, the successful applications of harvesting techniques by use of trained personnel and proper harvesting equipment are essential to reduce both the incidence and severity of ***, the careful selection of postharvest handling temperature and other treatments can increase resistance of fresh produce to bruise damage.
