Abstract
The survival rate of carp spawn in nursery
ponds is generally very low because of harmful aquatic insects that prey
intensively on carp spawn and early fry. These insect pests occur in large
numbers throughout much of the year, particularly during and after the rainy
season. Backswimmer (Notonecta glauca) (family
Notonectidae) are predatory aquatic insects that pose a threat to fish in
aquaculture. This study evaluated the efficacy of six treatments, Diesel-detergent
mixture, Diesel, Turpentine oil, Neem oil (Azadiractin %), Kerosene, and Garlic
juice on backswimmer management and their effects on water quality over 24
hours in aquarium condition. Backswimmers and common carp hatchlings were
collected from nurseries pond and stocked in aquarium where 10 L per aquarium
water volume maintained. Turpentine oil rapidly eliminated backswimmers within
10–20 minutes, while Diesel and Diesel-detergent mixture required 20–30
minutes. LC50 value of neem oil caused temporary fish sedation,
Kerosene required 24 hours for complete control, and Garlic juice resulted in
low fish survival (30%) and water quality deterioration. Water quality
parameters, including dissolved oxygen, alkalinity, ammonia, hardness,
phosphate, nitrate, and nitrite, were significantly affected by treatments (p
< 0.001). Turpentine and Diesel-based treatments maintained stable water
quality and high fish survival, indicating their suitability for backswimmer
management in aquarium.
