This study investigated the impacts of various inclusion levels dietary potential fish protein hydrolysate (FPH) on growth and reproductive performance, biochemical composition, blood parameters, liver histology Ompok pabda broodstock. About 600 broods (11.00 ± 0.05 g) were distributed into 12 cages fed twice in a day. For this, four experimental diets (crude protein: 30%; crude lipid: 9%) prepared by incorporating FPH at different percentages (0%, 5%, 7%, 9%). The positively impacted ( $p<0.05$ ) durability index, water stability, swelling rates diets. Furthermore, significantly higher palatability id="M2">p<0.05 was recorded for incorporated with 5% 7% FPH.

Assessment of Fruit Waste as Feed Additives in Aquafeed for Growth Performance and Health Benefits of Fishes Under Biofloc Technology

Reviews in Aquaculture, Journal Year: 2025, Volume and Issue: 17(2)

Published: Feb. 11, 2025

ABSTRACT The rising demand for fish and crustacean products has placed significant pressure on traditional aquaculture practices, which are increasingly unsustainable. Utilizing fruit waste as a feed ingredient in biofloc systems presents promising solution enhancing the sustainability cost‐efficiency of farming. Studies have demonstrated that incorporation into aquafeed improves growth performance, utilization, health outcomes aquatic animals. This practice also addresses management issues reduces dependency conventional ingredients, becoming more expensive. However, factors such availability scalability waste, remain important considerations. Research shown fed diets supplemented with exhibit superior growth, survival rates, compared to those diets. highest weight gain specific rates were observed fishes, normal liver intestinal histopathology. Additionally, significantly enhanced hematological parameters, hemoglobin, red blood cells, white leading improved immune responses resilience during stress.

Perspective Chapter: Sustainable Management and Utilization of Agricultural Waste – Innovations, Challenges, and Future Prospects

IntechOpen eBooks, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Agricultural waste (crop residues and animal manure) is a significant byproduct of farming activities. It holds potential for sustainable agriculture, renewable energy production, environmental conservation. However, traditional disposal challenges persist, leading to air pollution soil degradation. Innovative approaches include converting agricultural into bioenergy like bioethanol biogas producing biochar from residues, which improves health, water retention, nutrient availability while sequestering carbon. also finding applications in industries. Integrating industrial processes not only adds value but reduces reliance on raw materials fossil fuels wood. In livestock farming, crop are critical as feed bedding, particularly resource-constrained regions. While their nutritional content often low, treatment methods can improve digestibility. By integrating cutting-edge technologies supportive policies, it possible transform burden resource, paving the way more future.

Importance of Minerals and Their Bioavailability in Boosting Aquaculture: A Systematic Review

Aquaculture Fish and Fisheries, Journal Year: 2025, Volume and Issue: 5(3)

Published: May 5, 2025

ABSTRACT Fish like other terrestrial animals, have specific requirements for individual minerals that support the growth and maintenance of normal fish health biological functions among different cultured species. These can be either macro or micro are supplied to body through diets absorbed from their surrounding environment via skins, gills alimentary tract. However, bioavailability these is influenced by several factors, including intake level nutrient, interactions with nutrients To enhance effective farmed fish, sustainable, healthy well‐mineral‐balanced must adopted achieve better performance, a high survival rate production productivity while ensuring resilience environment. In this review, quantitative mineral composition sources was reviewed reported. addition, in both freshwater marine water species five (calcium, phosphorus, sodium, potassium magnesium) seven (zinc, iron, copper, manganese, iodine, chromium selenium) were compiled Nile tilapia dominating Tanzania, followed catfish rainbow trout, milkfish practiced along coastline Northern Tanga region Southern Mtwara region. Moreover, review also covers information on relationship between mechanism absorption implications associated aquatic animal environment, as well research future perspectives aquaculture industry development. Therefore, comprises all importance sustainable productivity.

Supplementation of Mangiferin to a High-Starch Diet Alleviates Hepatic Injury and Lipid Accumulation Potentially through Modulating Cholesterol Metabolism in Channel Catfish (Ictalurus punctatus)

Antioxidants, Journal Year: 2024, Volume and Issue: 13(6), P. 722 - 722

Published: June 13, 2024

Starch is a common source of carbohydrates in aqua feed. High-starch diet can cause hepatic injury and lipid accumulation fish. Mangiferin (MGF) regulate metabolism protect the liver, but there limited research on its effects In present study, we investigated whether MGF could ameliorate high-starch-induced damage channel catfish. The catfish (Ictalurus punctatus) were fed one four experimental diets for eight weeks: control (NCD), high-starch (HCD), an HCD supplemented with 100 mg/kg (100 MGF), 500 (500 MGF). results demonstrated that weight gain rate (WGR) (p = 0.031), specific growth (SGR) 0.039), feed conversion efficiency (FCE) 0.040) group significantly higher than those NCD group. supplementation alleviated liver improved antioxidant capacity (T-AOC) compared to 0.000). addition, dietary reduced plasma glucose (GLU) 0.000), triglyceride (TG) (p= 0.001), low-density lipoprotein cholesterol (LDL) 0.000) levels. It noteworthy total (TC) levels TC 0.005) Dietary improves homeostasis by decreasing expression genes are involved synthesis transport (hmgcr, sqle, srebf2, sp1, ldlr) increasing catabolism (cyp7a1). Among them, largest fold decrease squalene epoxidase (sqle) was observed or groups group, significant 3.64-fold 2.20-fold 0.008).
