“…Meanwhile, the L. lactis treated groups showed a remarkable decrease in Hg residue level, where there was a non‐significant difference between Hg+ L. lactis 10 and Hg+ L. lactis 9 groups. Our results were supported by Ayyat et al (2020) revealed a significant decrease in Hg residues in Nile tilapia tissues following dietary supplements with Bacillus toyonensis (BT) and B. subtilis (BS).…”

“…Hence, the adverse effects of SLPC and CLPC protein may be attributable to the decreasing the CP and/or crude lipids digestibility compared with fish fed feed without LPC (Ngugi et al, 2017). Plant feedstuffs used in the fish feed may influence digestion efficiency by the presence of one or more antinutritional factors (ANFs; Ayyat et al, 2020; Francis et al, 2001). The occurrence of one of the ANFs such as tannins, oxalates, saponins and phytates could be reduced the bioavailability of some essential nutrients, consequently decreasing fish performance.…”

A 12‐week feeding experiment was performed to examine the impacts of partial or complete substitution of soybean meal (SM) with leaf protein concentrate from carrot and sugar beet (CLPC and SLPC) on growth, blood constituents and body composition in Oreochromis niloticus. Five isocaloric (gross energy, 4300 kcal/kg) and isonitrogenous (crude protein, 320 g/kg) diets were formulated. The basal diet was formulated to contain SM at 350 g/kg diet. SM was replaced by 50% and 100% of SLPC and CLPC (SLPC‐50, CLPC‐50, SLPC‐100 and CLPC‐100 respectively). The results revealed that there were no significant changes in the growth indices between fish fed on basal diet and SLPC‐50 and CLPC‐100 diets. The condition factor was significantly increased in all dietary SLPC and CLPC substitution levels. Feed intake, feed conversion ratio and survival rate were not altered by various dietary SLPC and CLPC levels. The inclusion levels of SLPC and CLPC in fish feed did not significantly affect most blood biochemical and haematological parameters. Except for the SLPC‐50 group, all substituted groups displayed a significant depletion in the crude lipid content compared with the non‐substituted group. Fish fed on CLPC‐100 diet recorded the lowest feeding cost and best profit margin compared with other experimental groups. In summary, the findings demonstrated that SLPC and CLPC could replace 50% and 100% of SM, respectively in O. niloticus feeds without any negative effects on growth and blood constituents. Besides, the total replacement of SM with CLPC was more efficient in producing low cost and healthy aquafeed.

“…Blood biochemical indicators are crucial for assessing fish health, toxicity, and biomonitoring [ 65 , 66 , 67 , 68 ]. Herein, fish exposed to MET developed apparent anemia and a significant decrease in total leukocyte count with a parallel decline in heterophils, lymphocytes, monocytes, and eosinophils.…”

Dietary Parsley Seed Mitigates Methomyl-Induced Impaired Growth Performance, Hemato-Immune Suppression, Oxidative Stress, Hepato-Renal Damage, and Pseudomonas aeruginosa Susceptibility in Oreochromis niloticus

et al. 2022

The present experiment investigated the potential protective role of parsley (Petroselinum crispum) seed meal (PSM) in alleviating methomyl (MET)-adverse impacts on growth, whole-body composition, hematological indicators, hepatorenal function, immune response, oxidative status, and disease resistance to Pseudomonas aeruginosa. For this purpose, 225 healthy Nile tilapia (Oreochromis niloticus) were allotted into five groups (45 fish/group in triplicate). One group was reared in clean water and fed a non-supplemented basal diet, while the other groups were exposed to 20.39 μg L−1 MET and fed a non-fortified basal diet or basal diets supplemented with 0.5, 1.0, or 2.0% of PSM for 60 days. The obtained data revealed significantly lower weight gain, feed intake, and specific growth rate, but higher feed conversion ratio and decreases in crude protein, lipid, and ash contents in the MET-exposed fish. Anemia, leukopenia, lymphocytopenia, and esonipenia were also obvious. Furthermore, MET-exposed fish had significantly higher serum levels of hepatic enzymes and renal damage products. Nevertheless, there was a significant depletion of enzymatic and non-enzymatic antioxidants and increased malondialdehyde, myeloperoxidase, and tumor necrosis factor-α levels in MET-exposed fish. The MET exposure significantly depressed lysozyme activity, nitric oxide, complement3, acetylcholinesterase activity, total proteins, globulin, and albumin levels in O. niloticus serum. Furthermore, pathological alterations in the liver and kidney were noted. The relative percentage of survival rate in MET-exposed fish was dramatically reduced on day 14 post-challenge with P. aeruginosa. The inclusion of PSM, on the other hand, greatly alleviated most of the MET-related negative effects. Taken together, the dietary intervention with PSM has a promising role in alleviating MET-deleterious impacts, rendering parsley seeds a viable aqua feed additive for O. niloticus.
