“…A significant part of them is related to fish nutrition, as marine fish larvae are extremely vulnerable during their early stages of development, and they have specific biotic and abiotic requirements to survive, develop, and grow properly (Hamre et al, 2013). Results from the literature indicate that supplementation of good quality dietary protein (Kvåle et al, 2009), phospholipids (Tocher et al, 2008), n‐3 highly unsaturated fatty acids (Hamre et al, 2013), minerals such as iodine and selenium (Hamre et al, 2008), vitamins such as the vitamin D3 (Sivagurunathan et al, 2022), and probiotics (Piccolo et al, 2015), affect the survival rate of fish positively.…”

The economic impact of skeletal anomalies in aquaculture farming is a significant issue for the industry, as deformed fish are frequently discarded because of their low survival rate and a variety of other disadvantages, including increased costs, consumer distrust of aquaculture products, and ethical concerns. The goal of this article is to propose a method for calculating the direct costs of severe skeletal anomalies in typical Mediterranean seabream and seabass aquaculture hatcheries using a deterministic static model programmed in MATLAB that simulates their annual operation. Our findings suggest that larger hatcheries experience higher direct costs associated with severe skeletal anomalies but have better financial stability and significantly higher expected profits. Mean results indicate that the annual economic losses of severe skeletal anomalies for seabream and seabass Mediterranean aquaculture are 22.88 million euros per year for a scenario of low severe skeletal anomalies, 65.34 million euros per year for a scenario of medium severe skeletal anomalies, and 115.98 million euros per year for a scenario of high severe skeletal anomalies. Furthermore, some options for increasing the financial stability of the hatcheries are to increase the sale price of fingerlings, reduce the feed conversion ratio, and reduce the feed unit cost.

The contribution of phosphorus to water body eutrophication is a global environmental problem, and rapid increases in aquaculture are considered a significant source of phosphorus discharged into the environment. The current review focuses on the source of aquaculture waste phosphorus and measures to decrease phosphorus release into the environment. Because diets are a significant source of phosphorus in fed aquaculture systems, improving the utilization efficiency of dietary phosphorus can reduce the amount of waste phosphorus at the source. A wide range of removal and recovery technologies has been identified, including adsorption, crystallization, enhanced biological phosphorus removal (EBPR), denitrifying phosphorus removal, heterotrophic nitrification aerobic denitrification (HAND) and photosynthetic organism removal. Recovery technologies were also reviewed, particularly sludge phosphorus from recirculating aquaculture systems. A new method using bacteria to immobilize waste nitrogen and phosphorus into bioflocs has been proposed as a better solution. However, most of these technologies have only been implemented at the lab scale to pilot scale. Further studies are necessary to determine the working conditions and removal capacities of related technologies on a commercial scale.Moreover, phosphorus removal methods must be selected based on a consideration of recyclability.

“…Furthermore, the presence of skeletal anomalies negatively impacts the well-being of the fish, as deformed fish can be more susceptible to parasites (i.e., when opercular reductions are present) or feed less effectively (if affected by severe anomalies in the jaws or vertebral column). The zootechnical approaches aimed at increasing production quantity have led researchers to investigate the effects of genetic variability and fitness, inbreeding, selective breeding of desired quantitative traits (Afonso et al, 2000;Berillis, 2017;Fragkoulis et al, 2018Fragkoulis et al, , 2020, proper nutritional requirements (Baeverfjord et al, 2019;Cahu et al, 2003;Darias et al, 2011;Dominguez et al, 2021Dominguez et al, , 2022Ferosekhan et al, 2022;Georga et al, 2011;Izquierdo et al, 2017Izquierdo et al, , 2019Lall & Lewis-McCrea, 2007;Sivagurunathan et al, 2022;Tseng et al, 2021); and the use of superficial skimmers (Chatain & Ounais-Guschemann, 1990), on growth and skeletal quality (viz. targeting to reduce the incidence of skeletal anomalies).…”

“…In this scenario, this study aims at verifying if the same positive effects of low rearing density and mitigating effects of greater available water volume on the development of skeletal anomalies are detectable in gilthead seabream reared during the hatchery (larval rearing) phase from eggs up to 60 dph, in two different water volumes (1000 vs. 500 L), and stocked at three different initial densities. This approach foresaw: (i) that the tested densities were those considered of interest to fish farmers (Italian Fish Farmers Association (API)); (ii) that the water volumes were identical to those previously used in the experimental rearing during the pre‐ongrowing phase in the same species (Dellacqua et al, 2023) and were significantly larger than tanks or aquaria often used for experimental studies on model fish (1–3 L Di Biagio et al, 2022; Martini et al, 2021), and commercial species like gilthead seabream (170–200 L Dominguez et al, 2021; Dominguez et al, 2022; Izquierdo et al, 2017; Izquierdo et al, 2019; Sivagurunathan et al, 2022; Tseng et al, 2021). Furthermore, these large tanks required a very large number of fish (initial number of eggs = 615,385) to be subjected to the experimental trial.…”

This study describes the effects on the skeletal phenotype of two pivotal factors, density and water volume, don the hatchery (larval) phase of gilthead seabream (Sparus aurata) larvae previoulsy described for two model species (Danio rerio and Oryzias latipes) and sub‐adult (pre‐ongrowing) gilthead seabream (Sparus aurata). The experimental trial was conducted using single conditions in a pilot study, starting with a total of 615,385 eggs from the same batch. Three densities (LD low density: 25 larvae/L; MD medium density: 125 larvae/L; and HD high density: 250 larvae/L) and two water volumes (500 and 1000 L) were tested from spawning up to 60 days post‐hatching (dph) (average standard length: 1.79 cm; average dry weight: 27.11 mg). On the final samples, morphometric, anatomical, and histological data were collected for data pertinent to meristic counts and skeletal anomalies. The results (analyzed by means of multivariate analyses) indicated that the LD‐reared larvae were significantly longer and heavier than HD‐reared fish. Furthermore, LD‐reared gilthead seabream exhibited a significant reduction in the frequency of individuals with anomalies of jaws, vertebral body shape, and vertebral arches than the MD and HD conditions, which is in agreement with previous experiments carried out on model species and gilthead seabream sub‐adults.
