“…These factors induced the formation of an agricultural sector characterized by a diverse production on familiar basis. Main agricultural products are: pork and poultry (managed by agro-industries integrated with small farmers), corn, soybean, wheat and beans (Testa et al, 1996;Boll and Garádi, 1995). In these small farms in the south region of Brazil the integration of production occurs by using corn as the main component for pig diet.…”

The present study uses emergy methodology to evaluate environmental aspects of integrated production systems of grains, pig and fish in small farms in the South region of Brazil. New emergy parameters that use partial renewability factor of each input were used to improve emergy accounting. These parameters were already applied to different case-studies and are very appropriate for use in emergy assessment of integrated agricultural systems. The following indicators were calculated for the integrated production system of grains, pig and fish: Transformity: 948,000 sej/J; Renewability: 24%; Emergy yield ratio: 1.44; Emergy investment ratio: 2.28; Environmental loading ratio: 3.13 and Emergy exchange ratio: 6.8. These values were compared with results calculated for grains, pig and fish production subsystems working in a separated way. The results obtained signalize that an integrated system has better emergy efficiency, is more sustainable and is less stressful on the environment in comparison with separated production subsystems. The emergy indicators presented are discussed in the text and they will be useful in further work to assist the formulation of public policy.

“…The western region of the state of Santa Catarina, Brazil, is one of the most important traditional agricultural regions in the country, due to its exceptional poultry-and swine-farming production. This region also has a well-established meat industry based on pork and chicken in a successful integration model involving thousands of family farmers (Boll & Garádi, 1995). Due to its extraordinary development in the food industry, several mostly small and medium-sized farmers, are also involved in freshwater fish cultivation using earthen ponds (Silva et al, 2017).…”

“…With the introduction of Chinese carps (Ctenopharyngodon idella -grass carp, Hypophthalmichthys molitrix -silver carp, Hypophthalmichthys nobilis -bighead carp, Cyprinus carpio -common carp) and Nile tilapia (Oreochromis niloticus) into Santa Catarina State, several initiatives were taken by EPAGRI (Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina) to promote the cultivation of freshwater fish: (a) providing technical support to family farmer producers, (b) inserting fish cultivation into the curriculum of agricultural high schools, (c) encouraging the formation of producer associations, (d) offering courses on fish by-products, and (e) promoting fresh fish markets. These markets frequently occur in inland cities during the Easter period, when the consumption of fish is highly traditional in Brazil, and consumers can buy fresh fish directly from the farmers at the markets (Boll & Garádi, 1995;Matos & Matos, 2018b).…”

There is a paucity of information about the chemical composition of commercially important freshwater fish species (Nile tilapia, bighead carp, grass carp, common carp and silver carp) cultivated in the western region of Santa Catarina, Brazil. This study determined the moisture, ash, protein and lipid contents and the fatty acid composition, as well as the nutritional quality of the lipids in fillets of these five freshwater fish species. Moisture was the most prominent fish component (74.7%-81.7%), followed by protein (15.8%-18.8%) and lipids (0.4%-8.2%). Saturated palmitic acid (90-1740 mg/100 g) and monounsaturated oleic acid (70-2260 mg/100 g) were the major fatty acids found in all the fish species. The grass and common carps and Nile tilapia (caged) had high contents of γ-linolenic acid (GLA), with an average of 536 mg/100 g. Bighead carp was the richest source of ω-3 PUFA, mainly eicosapentaenoic (EPA, 400 mg/100 g) and docosahexaenoic (DHA, 620 mg/100 g) acids, and had the highest ω-3/ω-6 ratio of 6.11. The nutritional evaluation of the fatty acid profile indicated that average values were: atherogenicity index (AI) ~0.59, thrombogenicity index (TI) ~0.82, hypocholesterolemic/hypercholesterolemic ratio (H/H ~1.98), polyunsaturated/saturated ratio (P/S) ~0.43 and ω-3/ω-6 ratio ~2.18, values suggesting that the consumption of these freshwater fish species could be of benefit to human health.
