FISHING, PROCESSING, COMMERCIALIZATION AND A PROPOSE TO FISHERY WASTE REUSE OF SURURU Mytella falcata IN THE MUNDAÚ LAGOON, MACEIÓ – AL, BRAZIL

Abstract

A diagnosis was made on the fishing, processing, commercialization and generation of residues of the sururu fishery in Mundaú lagoon, Maceió-AL. Thirty nine fishermen were interviewed and also incursions were made for observations. Furthermore, sururus were collected to perform biometry. Residue of the sururu processing was collected to the fabrication of sururu waste meal (SWM), posteriorilly its bromatological composition was analysed. Fishermens of sururus fish 4.56 times week-1 and each fishing excursion lasts 5h26min, yielding 18.61 cans (18.61 to 37.22 kg soft tissue). Besides the sururus, 77.92% also catch fish, shrimp, and other organisms to complement the income. Average selling price was R$ 6.92 per kg of edible and CPUE from 3.42 to 6.85kg edible day-1. The average size and weight are 33.21 mm and 1.62 g, with 782.53 g of waste being generated to produce 1.0 kg of meat. SWM contained 37.00% calcium. It was verified that there is a need to create a management plan capable of reducing environmental impact in the lagoon, implement fishing programs and waste management, as well as improve the structure for the processing of that mollusc. Studies of the use of SWM as a source of calcium in diets are also recommended.

Analysis of Environmental and Sanitary Knowledge of Shellfish Gatherers in Vergel Do Lago, Maceió/Al-Brazil, Before and After Educative Action

“…Silva et al (2010) stated that the shells of some mollusks can constitute about 70.00% of their weight and, as they are not used for human consumption, the disposal of large quantities causes environmental impacts, although their shells are not considered potentially hazardous waste. In the case of sururu shells, Tamano et al (2020) performed a biometric analysis and determined that the weight of the shells may represent 43.90% of the mollusk weight and that, based on statistics from official fishing production agencies, 889,532.00 kg of shells were generated in Alagoas alone between 2001 and 2009. Although the official data are very inaccurate, quite underestimated, this demonstrates the potential for the generation of shell volumes.…”
