“…The influence of water hardness on growth of larval teleost fish has been a subject of particular interest, and a considerable amount of information has been published on the topic. Although responses to calcium‐limited environments are variable between species, which is to be expected in such a diverse group as teleosts, some generalizations to low ambient calcium availability can be made and have been described in previous reviews of the literature (Guerreiro & Fuentes, ; Howells, Brown, & Sadler, ). Typically, larval fish exhibit tight control over calcium levels very early in development, and ion‐limited environments usually elicit compensatory uptake responses (Chen, Lu, & Hwang, ; Hwang, Tung, & Chang, ).…”

A variety of environmental factors are known to influence growth rate and survival of larval fish. The effects of water chemistry, such as calcium hardness of freshwater systems, have been reasonably well-described in teleosts in the early life stages. However, the Lake Sturgeon, Acipenser fulvescens, is unusual in the conjunction of high calcium demand for growth in early life (as in all vertebrate animals), but low internal calcium reserves due to relatively few bony structures, especially in early life. This study reared Lake Sturgeon from hatch until after first feeding in 0.1, 0.2 and 1.5 mM [Ca 2+ ]. No differences were observed between rearing environments in hatching success or survival.Fish reared in the lowest [Ca 2+ ] demonstrated earlier significant increases in wet weight and total length, and absorbed yolk at a faster rate. Fish in all treatments accumulated Na + and Cl − throughout the pre-feeding stages and continued to increase whole-body [NaCl] in the calcium-limited water after feeding. Continued growth of fish in the lowest calcium concentration was significantly impacted as the fish grew, suggesting that water chemistry was an important influence on developmental progression, and therefore, factors relevant to long-term survival such as condition and available time for feeding onset to occur.

“…In teleosts, mineral homeostasis is regulated by more than 10 hormones (Arnold et al, 2021; Flik et al, 2009; Lin & Hwang, 2016). Among them, calcitonin (CT) and parathyroid hormone (PTH) are known as antagonists of calcium transport and relocation (Drake & Gupta, 2021; Guerreiro & Fuentes, 2019). CT is a hypocalcemic hormone (Chakrabarti & Mukherjee, 1993; Chan et al, 1968; Srivastav et al, 1998) that acts via inhibiting bone demineralization, osteoclastic activity, and gill calcium uptake (Mukherjee et al, 2004; Suzuki et al, 2000).…”

Adaptation to different environments can be achieved by physiological shifts throughout development. Hormonal regulators shape the physiological and morphological traits of the evolving animals making them fit for the particular ecological surroundings. We hypothesized that the artificially induced hypersynthesis of calcitonin and parathyroid hormone mutually influencing calcium metabolism could affect bone formation during early ontogeny in fish imitating the heterochrony in craniofacial ossification in natural adaptive morphs. Conducting an experiment, we found that the long‐standing treatment of salmonid juveniles with high doses of both hormones irreversibly shifts the corresponding hormone status for a period well beyond the time scale for total degradation of the injected hormone. The hormones program the ossification of the jaw suspension bones and neurocranial elements in a specific manner affecting the jaws position and pharingo‐branchial area stretching. These morphological shifts resemble the adaptive variants found in sympatric pelagic and demersal morphs of salmonids. We conclude that solitary deviations in the regulators of calcium metabolism could determine functional morphological traits via transformations in skeletal development.
