    OCCURRENCE OF SOUTH AMERICAN SUCKER ARMOURED CATFISH (PTERYGOPLICHTHYS PARDALIS) IN THE GAYATHRIPUZHA RIVER, PALAKKAD, KERALA
    (International Journal of Fisheries and Aquatic Studies, 2023) Veena, V; Sasikala, G; Selvaraju, Raja
    An intensive survey was undertaken and reported the existence of an invasive armoured sailfin catfish Pterygoplichthys pardalis from the Bharathapuzha River, Palakkad, Kerala, India, and its invasion as one of the foremost threats to the endemic aquatic biodiversity of Kerala. It belongs to the Genus Pterygoplichthys (Siluriformes: Loricariidae) which is known as popular aquarium fish that constitutes one of the most successful aquatic freshwaters invasive taxa, having achieved global distribution. The invasion occurred through aquarium fish culture and trading and is intensified by the distribution through rainstorm flooding and irrigation canal. The fish were identified based on morphological tests, identified fishes ranged in length (9.50-31.75cm) and weight (8.16-129.80 g). Distribution leads to understanding the changes and disturbances in fish species composition and the negative impact on the riverine ecosystem.

    A STUDY ON THE PHARMACOLOGICAL EFFECTS OF A FLAVONOID-RICH COSTUS IGNEUS AND TRIGONELLA FOENUM-GRAECUM FOLIAGE ON A DIET-INDUCED OBESE ZEBRAFISH (DANIO RERIO)
    (Journal of Advanced Zoology, 2024) Alis Rega, S; Sasikala, G
    The prevalence rates of Obesity and diabetes are steadily increasing worldwide for the past several decades. Many commercial drugs are available for use in the management of diabetes. However, their side effects and high costs emphasize the need for herbal alternative drugs. The present study was designed to evaluate the effect of a flavonoid-rich extract of insulin plant (Costus igneus) and Fenugreek (Trigonella foenum-graecum) foliage extract on diet-induced zebrafish. Methods: Adult zebrafish were divided into four diet groups: (i) control fed (CF); (ii) overfed (OF); (iii) OF supplemented with insulin plant (OF+I); and (iv) OF supplemented with fenugreek foliage (OF+F). The euthanized zebrafish were analyzed for body weight, BMI, Blood glucose, and Triglyceride (TG) level at the end of the fourth week. Results: Fenugreek foliage significantly decreased BW, BMI, Blood glucose, and Triglyceride levels in OF zebrafish. Moreover, Histopathological evaluation showed excessive fat accumulation in obese zebrafish liver indicating Non-alcoholic Fatty Liver Disease (NAFLD) when compared with insulin plant. Conclusion: This study adds a new insight into the anti-obesity properties of insulin plant and fenugreek foliage and its flavonoids, as weight management agents.
