Urinary calculi in larvae of striped trumpeter, Latris lineata

Abstract

Urinary calculi, also known as urinary stones, precipitates or urolithiasis, result from the aggregation and crystallization of minerals in the urinary system (Bazin et al., 2007;Senzaki et al., 2004).The presence of urinary calculi has been reported from larvae of various marine fish species, including brown-marbled grouper

Embryonic and early larval development of Florida pompano, Trachinotus carolinus

“…Histological alterations associated with cystic calculi in teleost larvae include urinary papilla obstruction and urothelium pressure atrophy, although these alterations were not seen in this study (Dias et al, 2022). Impacts of cystic calculi on larval survival are variably reported, but no effect on survival despite high occurrence of cystic calculi ($80%) was observed in snapper, P. auratus, mulloway, A. hololepidotus, or Australian bass, M. novemaculeata (Dias et al, 2022;Nowak & Battaglene, 1996). Associations between cystic calculi and subsequent nephrolithiasis or nephrocalcinosis in teleosts are still unclear (Dias et al, 2022).…”

“…Mesonephric tubules and glomeruli increased in number, and interspersed hematopoietic islands Boglione et al, 1995;Crespo et al, 2001;Dias et al, 2022;Giménez & Estévez, 2008;Kawasaki et al, 2017;Koumoundouros et al, 2004;Nowak & Battaglene, 1996;Peruzzi et al, 2004;Sivaloganathan et al, 1996). The causes and effects of cystic calculi in these species remain unclear, but both environmental (salinity and temperature) and nutritional (dietary mineral and taurine) factors have been shown to play a role (Dias et al, 2022). Histological alterations associated with cystic calculi in teleost larvae include urinary papilla obstruction and urothelium pressure atrophy, although these alterations were not seen in this study (Dias et al, 2022).…”

“…Cystic calculi have been noted in other marine teleost larvae reared in aquaculture including sea bass, Dicentrarchus labrax , brown‐marbled grouper, Epinephelus fuscoguttatus , Japanese flounder, Paralichthys olivaceus , common dentex, Dentex dentex , gilthead sea bream, Sparus aurata , snapper, Pagrus auratus , mulloway, Argyrosomus hololepidotus , Australian bass, Macquaria novemaculeata , and striped trumpeter, Latris lineata (Allon et al, 2016; Boglione et al, 1995; Crespo et al, 2001; Dias et al, 2022; Giménez & Estévez, 2008; Kawasaki et al, 2017; Koumoundouros et al, 2004; Nowak & Battaglene, 1996; Peruzzi et al, 2004; Sivaloganathan et al, 1996). The causes and effects of cystic calculi in these species remain unclear, but both environmental (salinity and temperature) and nutritional (dietary mineral and taurine) factors have been shown to play a role (Dias et al, 2022).

“…In the present study, the embryonic pronephros of larval Florida pompano developed into the larval kidney during the first 7 dph. Mesonephric tubules and glomeruli increased in number, and interspersed hematopoietic islands Boglione et al, 1995;Crespo et al, 2001;Dias et al, 2022;Giménez & Estévez, 2008;Kawasaki et al, 2017;Koumoundouros et al, 2004;Nowak & Battaglene, 1996;Peruzzi et al, 2004;Sivaloganathan et al, 1996). The causes and effects of cystic calculi in these species remain unclear, but both environmental (salinity and temperature) and nutritional (dietary mineral and taurine) factors have been shown to play a role (Dias et al, 2022).…”

“…Developmental abnormalities can also be used as research endpoints to help improve environmental rearing conditions, and a more thorough understanding of Florida pompano organogenesis can inform diet selection and timing of other interventions such as prebiotic, probiotic, and nutrient supplementation. Early detection of abnormalities at this vulnerable life-stage can aid in selection guidance for stocking densities (Martini et al, 2021), disease detection (Dias et al, 2022;Lefebvre et al, 2004), identification of water quality issues (Ashaf- Ud-Doulah et al, 2021), and mitigation of toxicant exposures (Sant et al, 2016), to ensure optimal production. Furthermore, monitoring the health of cultured stocks from hatching through maturation and harvest can help increase consumer confidence in cultured fish health, humane husbandry, and seafood product quality.…”
