The experiment took place in rectangular earthen ponds with a surface area of 120 m² and a water depth of 1.5–2.0 m. The prawns in the treatment groups were fed commercial pelleted feed supplemented with probiotics. The results indicated a significant interaction effect on weight gain (WG), daily weight gain (DWG), daily growth rate (DGR), relative growth rate (RGR), specific growth rate (SGR), and survival. Overall, prawns treated with probiotics showed better growth performance compared to nontreated groups. Prawn cultured with P₁ at a stocking density of 4 m⁻² had better nutritional value, including higher protein level. The activity of prophenoloxidase (proPO), superoxide dismutase (SOD), and lipase enzyme was higher in probiotic-treated groups up to a stocking density of 6 m⁻² compared to control groups (<i>p</i> &lt; 0.001). Probiotic P₁ at stocking densities of 2 and 6 m⁻² showed a significant interaction effect on the protease activity, with other probiotics also enhancing protease activity compared to control. This study highlights that the growth performance, proximate composition, protease, and lipase activity, as well as proPO and SOD activity, of prawns can be improved through the application of probiotic P₁. In conclusion, the study suggests that commercial probiotics enriched with bacterial compositions like P₁ can be effectively used for culture intensification of prawns.</p>\u0000 </div>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2025 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/4397755","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this literature review was to aggregate the current knowledge on the status of basil production in aquaponic systems by identifying the different aquatic organisms cultured with basil and hydroponic subsystems cultured with basil species/varieties and address research gaps. Of the 100 reviewed publications, about 90% of the reviewed publications used sweet basil (<i>Ocimum basilicum</i> L.) and only three publications used a different basil species; holy basil (<i>Ocimum tenuiflorum</i>), lime basil (<i>Ocimum americanum</i>), or lemon basil, (<i>Ocimum africanum</i>). Of the publications that used sweet basil, Genovese was the most commonly used variety (21 articles), followed by Italian large leaf (6 articles) and purple ruffles (4 articles) varieties. Between the reviewed publications, 38.7% used deep water culture (DWC), 31.1% used media bed (MB), and 17.9% used nutrient film technique (NFT) to grow basil. Tilapia was the most commonly cultured species with basil in aquaponic systems (44%), followed by catfish (14%) and carp (9%). The amount of feed for tilapia <i>Oreochromis</i> sp. cultured as a function of grow space area ranged between 20.3 and 81.6 g feed/m²/day. Values ranged between 29.2 and 68.9 g feed/m²/day while culturing <i>Pangasius</i> sp., 20–25 g feed/m²/day while culturing catfish (<i>Ictalurus</i> sp.), and 4.4–16.9 g feed/m²/day while culturing carp (<i>Cyprinus</i> sp.). The variability in the fish feed-to-plant ratio suggests a need for establishing a recommendation for a species-specific optimal feed input that supplies sufficient nutrients for basil. The current review suggests further investigations comparing different basil varieties, cultivating different basil cultivars with different fish or crustacean species, using alternative hydroponic types, and evaluating feed inputs for establishing a recommendation for species-specific optimal conditions in aquaponic systems.</p>\u0000 </div>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2025 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/1320019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the potential negative effects of HA on aquatic ecosystems, especially fish, have not been fully investigated. This study examines for the first time the potential physiological, immunological, and histological effects of HA in African catfish, as well as the long-term implications following recovery. Four groups, totaling 24 African catfish in triplicate, were subjected to varying concentrations of HA (500–100,000 µg/L) over a 15-day exposure period, followed by a 15-day recuperation phase, leading to physiological changes dependent on the dosage. The electrolyte levels in the plasma and the equilibrium of redox processes were significantly upset by exposure to HÀ. Fish exposed to high HA concentrations displayed dose-dependent declines in immunological function and antioxidant enzymes. Only the fish exposed to modest doses of HA showed complete recovery when compared to the control fish, indicating that exposure to HA resulted in irreversible alterations. The histological investigations showed a number of dosage-dependent pathological alterations in the renal and hepatic tissues, including perivascular and peritubular fibrosis, tubular necrosis, and vacuolar degeneration. The degree of these alterations varied according to the dose. Concluding that fish may have irreversible alterations as a result of high acidity. The present study provides a fundamental understanding of the detrimental effects of HA on fish.

Using 16S rRNA gene sequencing, we sought to elucidate the effects of a cocultivation of <i>Chlorella vulgaris</i>, <i>Scenedesmus</i> species, and <i>Spirulina platensis</i> cocultivation on the bacterial communities in the rearing tanks and the biofilter of a garlic (<i>Allium sativum</i> L.) and Nile tilapia (<i>Oreochromis niloticus</i> L.) aquaponic system during a 56-days experiment.

Alpha-diversity analysis revealed significantly higher richness and evenness in the bacterial communities from the biofilter and rearing tanks of the cocultivated systems when compared with the control system. The cocultivation also had a statistically significant effect on the bacterial composition: nonmetric multidimensional scaling analysis of a Bray–Curtis dissimilarity matrix demonstrated unique clustering patterns, indicating distinct bacterial communities in the biofilter and rearing tank water cocultivated with microalgal strains. We found significantly decreased abundances of the potentially pathogenic bacterial genera <i>Janthinobacterium</i>, <i>Aeromonas</i>, <i>Pseudomonas</i>, and <i>Flavobacterium</i> in aquaponic systems cocultivated with microalgae when compared to the control.

Aquatic organisms, particularly larvae, instinctively prefer live feeds like algae and zooplankton; larvae are entirely dependent on live feeds due to their undeveloped digestive systems and lack of essential digestive enzymes. Additionally, fishes and crustaceans require essential nutrients, vitamins, and minerals for sexual maturity and giving birth to healthy offspring. Zooplankton plays an important role at larval feeding stages in cost-effective aquaculture. Rotifers, cladocerans, copepods, and <i>Artemia</i> are commonly applied in larval rearing. However, naturally live feeds are deficient in valuable nutrients. Consequently, live feeds are improved with essential vitamins, minerals, and amino acids through bio-enrichments and algal diets for better performance. Aquaculturists primarily prefer zooplankton as live prey of larvae in fish and crustacean hatcheries because larvae requires essential digestive enzymes. They always give priority to artificial feeds with minimum live feeds to maximize profit by lowering the cost. Remarkable case studies are discussed on cost-effectiveness of zooplankton in sustainable aquaculture in this manuscript. Therefore, zooplankton as live feed could be a better choice for their nutritional value, palatability, natural availability, and cost-effectiveness. The notable opportunities, challenges, and advanced researches in live feed culture are also described in this current study.
