Better Efficacy Helps Market Expansion of Natural Pituitary Gland
In Bangladesh, due to lack of availability of natural pituitary gland (PG) of local origin in the domestic market, imported synthetic hormone is used widely in the hatcheries for induced breeding. This is not encourage able from an economic, as well as safer fish seed production, point of view.
The Feed the Future Bangladesh Aquaculture and Nutrition Activity supported Fishtech Hatchery to establish a high-performing supply chain of natural PG of local sources. They have established seven PG collection centers and two PG processing plants to ensure a steady supply of PG to the local hatcheries in seven districts of the zone of influence (ZOI). To further prove the efficacy of the natural PG and synthetic hormone, Fishtech Hatchery conducted experiments and trials, and produced a scientific paper titled “Comparative Study on the Effectiveness of Natural Sources Hormone and Synthetic Hormone in the Induced Breeding of Cyprinus Carpio.” According to the study, the synthetic hormone accounted for 92.2% fertilization compared to natural PG that accounts 90.8%. However, natural PG-induced hatchlings have a substantially greater survival rate of 84.2% compared to synthetic hormones that provides a survival rate of 74.5%. Findings of the study was shared in the 9th Biennial Fisheries Conference and Research Fair 2022 on May 29, 2022, organized by the Bangladesh Fisheries Research Forum (BFRF). The findings have received overwhelming responses and appreciations from the participants of Bangladesh Agricultural University, Department of Fisheries, Bangladesh Fisheries Research Institute, Patuakhali Science and Technology University (PSTU), Quality Feed Company Ltd., ACI Ltd. and other government agencies, universities and private businesses.
To date, Fishtech Hatchery collected 2.5 kilograms (kg) PG from the local fish markets and processed in their facilities. They have sold 2.38 kg dry PG to 26 hatcheries and generated $182,000 in revenue. It is expected that the scientific findings on the efficacy of natural PG will influence the fish hatcheries in the country to replace the use of synthetic hormones by the use of natural dry PG of local origin and, thus, expand the market of natural dry PG nationwide.
