“…The gill histopathological lesions precipitated by graded concentrations of B. aegyptiaca were similar to the findings of Abalaka et al, [13] on C. gariepinus exposed to ethanolic extract of Parkia biglobosa, Gulhan et al, [33] on Oncorhyncus mykiss exposed to cypermethrin and Audu et al, [12] on Clarias gariepinus exposed to acute concentrations of Vernonia amygdalina. Oluwatoyin [10] and Adebola and Ayo [34] reported similar necrosis in the gills of O. niloticus and Heterobranchus bidorsalis, respectively. Also, the alterations in the gills of O. niloticus in the present study conform with the findings of Nasiruddin et al, [14] after treating Heteropneustes fossilis with three dry seed extracts.…”

“…Nkunya et al, [8] had earlier reported stem bark of B. aegyptiaca as a fish poison and thus been used to catch fish in lentic and lotic waters around the globe [9,7]. Nigerians are not left out in the use of plant materials for fishing [10].…”

“…Nasiruddin et al, [15] also reported disintegration of gill filaments and lamellae, degeneration of hepatocytes and blood vessels and necrosis of the intestinal epithelia of Heteropneustes fossilis exposed to 50% ethyl alcohol extract of three dry seed extracts (Lagerstroemia speciosa, Dipterocarpus turbinatus, and Hevea brasiliensis). In addition, Oluwatoyin [10] reported necrosis, cellular degeneration, malignancy and inflammation on the gills after exposure of O. niloticus to concentrations of Ipomoea aquatica.…”

Background: Histopathological changes have been widely used as biomarkers in determining the effects of pollutants on fish. Leaves of Balanites aegyptiaca, a deep-rooted, evergreen or semi-deciduous, multi-branched, spiny tree have been reported to have pesticidal, anaesthetic and ichthyotoxic effects. This study sought to find out the effect of sub-lethal concentrations (5.00, 11.00, 21.00, 43.00, and 86.00 mg/L) of B. aegyptiaca on histopathology of gills, kidney, and liver of mixed-sex Oreochromis niloticus fingerlings Methods: A total of 120 O. niloticus fingerlings (mean weight 23±0.03 g and mean total length 12.50±0.39 cm) were exposed to aqueous crude leaves extract of B. aegyptiaca. The gills, kidney, and liver were excised and processed routinely for the elucidation of histopathological changes Results: Dose-dependent histopathological changes were observed in the three organs (gills, kidney and liver) of O. niloticus exposed to graded concentrations of B. aegyptiaca. Gills showed moderate to severe secondary lamellae fusion, desquamation, and primary lamellae congestion while the kidney displayed mild to severe renal tubular epithelial cell degeneration and necrosis as well as pigmentation of renal tissues. The liver showed varying degrees of histo-architectural alterations such as hepatocellular degeneration and necrosis, cellular infiltrations, kupffer cell proliferation, portal, and sinusoidal congestions Conclusion: Owing to these histological alterations in the gills, kidney, and liver observed in this study, prolonged exposure of fish to B. aegyptiaca should be discouraged to preserve fish diversity

“…In recent years, the output of sea cucumber in China has increased year by year and the demand for rapid and large-scale mechanized processing technology and equipment is increasingly significant. In this context, many scholars have studied the effects of different processes and parameters (Sun et al, 2017;Liu et al, 2015) on the nutritional quality (Li et al, 2019b;Meng et al, 2017), texture-characteristics (Xiong et al, 2020;Xin et al, 2019) and edibility (Liu et al, 2018;Shaoxiao et al, 2017) under the condition of mechanical processing. However, there is no report on the effect of processing technology on the appearance quality of sea cucumber.…”

Aiming at the problem that the cleaning effect and surface integrity of the mechanical cleaning process cannot be solved simultaneously in the pretreatment of sea cucumber and according to the requirements of high efficiency, high quality and economy of sea cucumber body surface cleaning, a continuous directional cleaning device for sea cucumber abdomen and back based on the principle of water jet is designed. Through single factor experiment, the influence trend of jet parameters such as jet pressure, target distance and incidence angle on cleaning effect was analyzed. The cleaning parameters of sea cucumber are optimized by L9(3 4) orthogonal design. The experimental results show that the cleaning effect of sea cucumber is closely related to the impact of water jet. Enhancing the impact of water jet will not only help improve the cleanliness of sea cucumber, but also increase the risk of skin damage of sea cucumber. T he influence order of water jet parameters on the cleaning effect of sea cucumber is as follows: Jet pressure > jet target distance > jet incidence angle. When the jet pressure is 3.0 MPa, the jet target distance is 200 mm and the jet incidence angle is 70°, the cleanliness and integrity scores are 8.0 and 8.2 respectively and the comprehensive cleaning effect of this scheme is optimal. This study provides the basis for the research and development of sea cucumber water jet cleaning device and process optimization.
