A CHROMIUM (Cr⁶⁺) TOXICITY IN GALUNGGONG (Decapterus sp.) FROM COASTAL WATERS: EFFECTS ON REPRODUCTION

Chromium (Cr), a heavy metal possessing harmful oxidation states, contaminates coastal waters due tomanufacturing discharge, mining, and food production, harming economically significant species such asGalunggong (Decapterus sp.). Chromium accumulates in fish tissues, impacting reproduction and threat tosurvival of populations. Understanding chromium effects on Galunggong reproduction is crucial in assessingenvironmental threats as well as creating efficient management solutions. This investigation outlines the body ofstudies conducted to evaluate the amount of Chromium bioaccumulation on Galunggong species and itssubsequent effects on reproduction, gonadal development, reproductive hormone levels and general reproductiveeffectiveness. The techniques applied in previous studies are carefully examined, and data gaps regarding thespecific processes of Chromium toxicity on Galunggong are recognized reproduction. Efficient techniques formanagement to minimize chromium contamination and secure the reproductive health of commercially significantspecies while also protecting the larger coastal biodiversity will be established according to the results of the study.
