Abstract/ Executive Summary:

A study was conducted to compare the efficacy and growth performance of Orgavit aqua from “Organic Pharmaceuticals” on the growth of Pangus (Pangasianodon hypophthalamus) with other two commonly used growth promoters Aqua boost and Megavit aqua from “Novartis Company”. The experiment was done in the wet lab of Fisheries Technology Department, Bangladesh Agricultural University, Mymensingh. A total 12 newly constructed aquarium and 200 fish were used for this study. The three growth promoters were: used in separate nine (9) aquarium at recommended dose, lower dose, higher dose, respectively. Three aquarium were used for the control (diet without any promoter). Pellet feed were used with 10% body weight for each aquaria except control. Doses of, Orgavit-aqua were given as 1 mg, 3 mg and 5 mg/3 g feed/day, doses of Aqua-Boost were given as 1.0 mg, 1.7 mg, 2.0 mg/3.5 g feed/day and doses of Megavit aqua were given as 1 mg, 3 mg, 5 mg/3 g feed/day. Water was exchanged regularly and artificial air supplies were done continuously by aerator throughout the experimental period. The feeding trial period was conducted for 21days. Among the three growth promoters Orgavit aqua from “Organic Pharmaceuticals” showed better result at its recommended dose. On the other hand, Aqua-boost and Megavit aqua from “Novartis Company” showed better result at their higher doses.

Program Area: Variety and Species

Commodity: Pangus

Objectives:

To identify the Effect of three growth promoters- Orgavit aqua, Aqua boost, and Megavit aqua on growth of Pangus (Pangasianodon hypophthalamus)

Methodology:

Survey on price and quality of the growth promoters: It has been demonstrated that- in the growth and survival of fish, different growth promoters have different impacts. Therefore, before setting experiment on the effect of certain growth promoters, it was necessary to collect relevant information on them. Keeping this point in consideration, asurvey was conducted to justify the price and the quality of the growth promoters by visiting several markets, BFRI (Bangladesh Fisheries Research Institute) and Hatcheries. Setting of aquaria, and stocking and feeding of fish: Twelve aquaria each with a size of 2.5×1.5×1.5 ft³ and water holding capacity of 50 l were used for this experiment. The set up was facilitated with recirculating water supply by a pump and electricity facilities. Air was supplied to the aquaria by air pump (Guangdong Risheng Group Co., Ltd). For three different growth promoters four aquaria (four for each promoter) were used and in 3 aquaria recommended, higher and lower doses of these promoters were used along with pellet feeds. Among 4 aquaria one aquarium was treated as control in each case. Ten pangus (Pangasianodon hypophthalamus) with an average total length of 6.5 cm and average weight of 30-30.5 g were stocked in each aquarium. The fish were fed with a pellet feed (Biswas) at a rate of 10% of body weight. Proximate composition of the feed was estimated following AOAC (1990) standard protocols. The feeds with and without growth promoters were applied in 12 aquaria. Doses of three growth promoters (Orgavit aqua, Aqua boost and Megavit aqua), quantity of feed used and their effect on growth of pangus (Pangasianodon hypophthalamus)are shown in Table IV. Feed without any growth promoter wasused as control and applied to the fishes of 3 aquaria. This feeding trial was conducted for 21 days. During the experimental period, the weight of fishes of each aquarium was measured weekly using an electronic balance.

Achievement/Findings:

The study showed that- growth increment of fishes in aquaculture can be a great value when the growth promoters are used properly but improper application can cause grate loss of aquatic ecosystem and production. Therefore, it is important to apply proper growth promoters and best application method for aqua-production management. Pharmaceutical companies should conduct more and more research for reducing the harmful impact of aqua-medicine in aquaculture of country like Bangladesh. On the basis of obtained results the study could be concluded that growth promoters have positive impact on the growth and survival of fishes but before use the aqua medicines should be checked to avoid loss in ecosystem and aquaculture production. Like Aqua boost and Megavit aqua Orgavit aqua also has positive impact on the growth, survival and production of pangus fish and showed better result at its recommended dose.
