“…Lesnik and Jurcina (1994) reported that high doses may cause damage to the gastrointestinal tract, leading to a defect in the intestinal mucosa. Severe histological changes due to radiations were induced in aquatic organisms (Egami et al, 1984;Sadiq Bukhari et al, 2012;Stalin et al, 2013aStalin et al, , 2013b, which is in agreement to our results.…”

“…In work with Macrobrachium rosenbergii prawn exposed to concentrations of gamma radiation, it was possible to observe the prompt response of the gills that showed lamellar fusion, epithelial detachment, necrosis, and lamellar disorganization (Stalin et al 2013). In addition to the aforementioned species, Macrobrachium amazonicum, exposed to concentrations of 5 mg/L of total ammonia for 96 h also showed similar changes, such as cell swelling, lamellar epithelium thickening, hyperplasia, and lamellar epithelium lifting (Dutra et al 2017).…”

Considering that salts are widely used in prawn farming and that studies on their impacts on the aquatic ecosystem have not been identified, this study aimed to evaluate the possible changes caused by acute exposure of Macrobrachium jelskii prawn to sodium chloride and salt marine, through acute toxicity test and histopathological study. Prawn postlarvae (0.2112±0.34 g) were exposed to different concentrations of NaCl, 0 (control) to 26‰; and sea salt, 0 (control) to 35‰; for 96 h. In each duplicate treatment, seven prawns were kept in 2 L beakers for 96 h, with temperature, photoperiod, and pH-controlled, without any loss in the control group. To estimate the median lethal salinity (LS50-96h) the “Trimmed Spearman Karber method” program was used. The LS50-96h for NaCl was estimated to be 14.50‰ with a safety level of 1.45‰ and for the sea salt LS50-96h of 26.35‰ with a safety level of 2.63‰. It was also observed that at the concentration of 23‰ of artificial marine salinity, no mortality was observed, reflecting a narrow line between innocuous and deleterious salinity for M. jelskii post-larvae. At the end of the acute toxicity tests, the prawns were fixed and processed for staining in Hematoxylin and Eosin (H.E), Periodic acid-reactive Schiff (P.A.S), Blue Alcian (A.B), and Immunohistochemistry. For branchial histopathological studies, their histological sections were evaluated with an optical microscope. The main branchial alterations observed were hyperplasia, hypertrophy, cellular swelling, detachment of the respiratory epithelium, pillar cell rupture, some secondary lamella fusions, and necrosis.

“…Future studies should consider histological impacts on the crustacean gill using chronic, environmentally relevant radiation doses in order to corroborate this finding. A decrease in the hepatosomatic index of M. rosenbergii was also observed as a consequence of radiation exposure (Stalin et al, 2013b) which may provide further evidence that radiation elicits alterations to energy budgets since changes to the HSI may reflect mobilization and utilization of energy reserves (Sanchez-Paz et al, 2007).…”

“…Stalin et al, (2013a;2013b) demonstrated induction of histological and morphological aberrations including swollen and necrotic lamellae in the gill, deformations of the uropod, and discolouration of the abdomen in M. rosenbergii over a dose range of 3 -3000 mGy (Stalin et al, 2013a), with the magnitude of effects relating to dose. Iwasaki (1973) adopted a histological approach to assess gamma radiation-induced effects in oogonia and oocytes of the brine shrimp, Artemia salina.…”

The biological effects of ionising radiation on Crustaceans: A review

Historic approaches to radiation protection are founded on the conjecture that measures to safeguard humans are adequate to protect non-human organisms. This view is disparate with other toxicants wherein well-developed frameworks exist to minimise exposure of biota. Significant data gaps for many organisms, coupled with high profile nuclear incidents such as Chernobyl and Fukushima, have prompted the re-evaluation of our approach toward environmental radioprotection. Elucidating the impacts of radiation on biota has been identified as priority area for future research within both scientific and regulatory communities. The crustaceans are ubiquitous in aquatic ecosystems, comprising greater than 66,000 species of ecological and commercial importance. This paper aims to assess the available literature of radiation-induced effects within this subphylum and identify knowledge gaps. A literature search was conducted pertaining to radiation effects on four endpoints as stipulated by a number of regulatory bodies: mortality, morbidity, reproduction and mutation. A major finding of this review was the paucity of data regarding the effects of environmentally relevant radiation doses on crustacean biology. Extremely few studies utilising chronic exposure durations or wild populations were found across all four endpoints. The dose levels at which effects occur was found to vary by orders of magnitude thus presenting difficulties in developing phyla-specific benchmark values and reference levels for radioprotection. Based on the limited data, mutation was found to be the most sensitive endpoint of radiation exposure, with mortality the least sensitive. Current phyla-specific dose levels and limits proposed by major regulatory bodies were found to be inadequate to protect species across a range of endpoints including morbidity, mutation and reproduction and examples are discussed within. These findings serve to prioritise areas for future research that will significantly advance understanding of radiation-induced effects in aquatic invertebrates and consequently enhance ability to predict the impacts of radioactive releases on the environment.
