“…Koeberle et al . (2020) believed that the otolith perimeter and area of adult Chinook salmon ( Oncorhynchus tshawytscha ) from hatchery origins have higher CV 2 a than those from wild origins. Similarly, Xiangshan Bay is affected by spawning, breeding of marine organisms and mariculture activities throughout the year, and may be more polluted than Haizhou Bay (Li et al ., 2018).…”

“…A higher CV 2 a indicates a greater asymmetry between the right and left otoliths, and vice versa . For each character, the absolute deviance between the left otolith and right otolith measurements with respect to the left otolith measurement was calculated as follows (Koeberle et al ., 2020):

{italicMetric}_{ABC_deviance} = ({italicMetric}_{left} - {italicMetric}_{right}) / {italicMetric}_{left}

In recent years, the frequent occurrence of most human activities has seriously affected the structure and functioning of coastal ecosystems. The asymmetric relationship between the left and right otoliths of fish is often used to test the difference in fluctuating asymmetry (FA) reflected by the square of the coefficient of asymmetric variation (CV 2 a ), which can be regarded as an important step in the study of marine environmental pressure and implementation of offshore ecological restoration. In this study, the authors tested the bilateral FA of Collichthys lucidus in the coastal waters of Haizhou Bay, Jiangsu, and Xiangshan Bay, Zhejiang, China, using four sagittal otolith characters (length, width, perimeter and area) as biological characters. The results showed that the value of CV 2 a in otolith width (more sensitive to environmental pressure) of C. lucidus in Xiangshan Bay was higher than that in Haizhou Bay, indicating that the environmental pressure on Xiangshan Bay was relatively high. The authors did not find any significant differences in the FA of otoliths between different body sizes of C. lucidus, which may be related to the short-distance migration in different regions and the dietary shifts in the life history of this species.The results have conservation and management implications for this population.

“…Even though the rearing conditions try to create homogeneous conditions for the fish, they do not allow the fish to freely explore a broad range of micro-habitats that could theoretically allow the fish to actively seek the optimal conditions for its growth. Given that the stocked fish were reared in semi-intensive conditions (shallow ponds), they can be more vulnerable to other types of stresses than wild individuals, which can cause shifts on the otolith shape (Fernandez-Jover and Sanchez-Jerez, 2015;Koeberle et al, 2020;Vignon, 2018), because the later can perform vertical migrations to cope with temperature shifts (Lehtonen, 1983;Lind, 1977;Saulamo and Lappalainen, 2007). Also, given that captive fish inhabited different ponds before reaching Lipno reservoir, their growth and otolith shape could be influenced by these different environments in a non-linear way (i.e.…”

Otolith shape variations between artificially stocked and autochthonous pikeperch (Sander lucioperca)

Fish stocking is one of the most widespread and frequent management strategies in freshwater systems. However, the contribution of stocked fish to the population is seldom investigated, and hence the effectiveness of this strategy is virtually unknown for many populations. Understanding the contribution of stocked fish into the population is crucial because it allows the disentanglement of the confounding effects generated by allochthonous individuals into the estimation of survival and growth rates of the population. To discriminate between the allochthonous and autochthonous individuals in a population, the shape of sagittae otoliths from pikeperch (Sander lucioperca) where compared. Results indicated significant differences among stocked and non-stocked fish, with the former having smaller and wider sagittae otoliths than the later. Our results suggest that this technique can be used to discriminate the natal origin of fish in a much faster and cheaper way than commonly used techniques.

“…Otolith asymmetry in wild and cultured delta smelt (1.84-2.40%) was relatively similar to global estimates across numerous taxa (1.25-4.66%) 64 . Hatchery fish have been shown to exhibit up to threefold greater fluctuating asymmetry than wild fish 65 , though this trend is not consistent for all species 66 . Similarly, hatchery delta smelt exhibited 3-4 times higher asymmetry than wild fish, however, even the cultured values remained relatively low.…”

Developmental abnormalities in otoliths can impact growth and survival in teleost fishes. Here, we quantified the frequency and severity of developmental anomalies in otoliths of delta smelt (Hypomesus transpacificus), a critically endangered estuarine fish that is endemic to the San Francisco Estuary. Left–right asymmetry and anomalous crystalline polymorphs (i.e., vaterite) were quantified and compared between wild and cultured populations using digital image analysis. Visual estimates of vaterite were validated using X-ray diffraction, Raman spectroscopy, laser ablation ICPMS, and electron probe microanalysis. Results indicated that cultured delta smelt were 80 times more likely to contain a vateritic otolith and 18 times more likely to contain relatively large (≥ 15%) amounts of vaterite. Similarly, cultured fish exhibited 30% greater asymmetry than wild fish. These results indicate that cultured delta smelt exhibit a significantly higher frequency of vestibular abnormalities which are known to reduce fitness and survival. Such hatchery effects on otolith development could have important implications for captive culture practices and the supplementation of wild fish populations with cultured individuals.
