“…This value is lower than Souza and Inhamuns (2011) found when analyzing the same species, with average values of 3.92% and 6.33%, respectively. Barai et al (2022), in the flood and drought period, obtained higher yields than those reported in the study when evaluating the skin of the Amazonian species Astronatus ocellatus (Agassiz, 1831), Pellona castelnaeana (Valenciennes, 1847) and Leporinus friderici (Bloch, 1794). Meanwhile, for marine catfish Sciades herzbergii (Bloch, 1794), the value was higher (6.2%) than that of the current study (Vasconcelos-Filho et al, 2017).…”

“…According to Barai et al (2022), these differences in yield occur due to the morphometry of the species, which is essential data for the fish industries to avoid waste and add value to the by-product generated. In addition, the skin yield will depend on the operator's skill, so there are no excessive losses during this skin removal process (Oliveira Filho et al, 2020).…”

Fish processing provides waste of around 50.0% to 70.0% of the animal's initial weight, especially the skin. Thus, this residue contains the by-product that allows biopolymers to be obtained, highlighting collagen, which can be widely used in different areas. The present study aimed to evaluate the yield of collagen extracted from peacock bass Cichla monoculus skin and to characterize them physicochemically. Twenty-five peacock bass with an average weight of 646 ± 175 g were used. The skin samples were removed by manual filleting and weighed, with an average yield of 3.7%. Subsequently, such models were analyzed for chemical composition, showing 61.8% for moisture, 29.3% for crude protein, 1.5% for ash, 6.3% for total lipids, and 1.2% for non-nitrogenous extract (NNE). Acid-soluble collagen (ASC) presented an average yield of 8.2%, presenting in its analysis of centesimal composition 12.5% of moisture, 82.6% of crude protein, 1.1% of ash, 2.6% of total lipids, and 1.2% NNE. The skin and collagen extracted from the tucunaré skin have technological potential for use in the preparation of products, adding value to these by-products from fish processing.

“…In Salvelinus fontinalis Mitchill, Salmo trutta Linnaeus, 1758, and hybrid trout, differences in carcass yield were approximated by fat content (Şahin et al 2011). The same method was used for Astronotus ocellatus Agassiz, Pellona castelnaeana Valenciennes, and Leporinus friderici Bloch (Barai et al 2022). We did not analyze fat content, but the EOLG may have influenced the fish body composition and, consequently, the carcass yield.…”

Effect of Lippia grata essential oil as a feed additive on the performance of tambatinga juveniles

et al. 2022

Lippia grata (formerly known as Lippia gracillis) is an aromatic plant native to Brazil, with leaves rich in essential oils that possess significant biological activities. We evaluated the effect of essential oil of L. grata (EOLG) as a dietary additive on the growth, somatic indices, and biochemical parameters of juveniles (5.25 ± 0.26 g) of tambatinga, a hybrid fish obtained by crossing tambaqui (Colossoma macropomum) with pirapitinga (Piaractus brachypomum) of great economic importance in north and northeastern Brazil. We evaluated four dietary treatments, consisting of EOLG supplemented at 0.0, 0.5, 1.0, and 2.0 mL kg-1, over 60 days. Carcass yield was significantly higher in fish fed all EOLG diets compared to those fed the control diet (0.0 mL kg-1). Animals that received the 0.5 mL kg-1 treatment gained significantly more weight and showed a higher specific growth rate than those treated with 1.0 and 2.0 ml kg-1 EOLG, although none differed significantly from the control. The feed conversion rate was significantly lower in the 0.5 than in the 1.0 mL kg-1 treatment. Compared with higher concentrations, the diet containing 0.5 mL kg-1 EOLG increased the use of muscle glycogen, glucose, and lactate to meet energy demands, avoiding the use of muscle protein. Our results suggest that dietary supplementation with EOLG significantly improves carcass yield in tambatinga juveniles but that concentrations above 0.5 mL kg-1 may compromise growth rates and carbohydrate metabolism in this fish.

“…Little is the known about the nutritional value of these species, and how these influence the diet of the Amazon people. Recently, some studies were developed to understand and solve these research gaps, such as Yuyama et al (2011) and Tavares et al (2012) that carried out nutritional studies in several cities across the Amazonas state and detected a deficiency in some nutrients; while Barai, Souza, Viana, and Inhamuns (2021) evaluated meat yield and centesimal composition of some of the main Amazonian fish species in the drought and flood hydrological cycle.…”

For decades, researches were developed about the diversity of fishes in the Amazon basin and their consumption by the people. In this context, an important gap identified was a lack of information about the nutritional composition of some of the main Amazon fish species consumed and traded. Front this, the objective of this study was to evaluate the chemical composition and mineral content of filets from 10 fish species with the highest landing volume in Amazonas State. The fish species selected were curimatã, jaraqui, mapará, matrinxã, pacu, piramutaba, sardinha, surubim, tambaqui and tucunaré. Were collected 20 samples (fishes) from each species according to the hydrological cycles of the region (20 samples in the flood and 20 samples in drought). Ten fish samples were processed to determine the proximal composition and 10 fish samples were used to determine mineral content (macro and micro minerals). The proximal composition of fish species analysed varied widely between species and seasons, with an emphasis on moisture and lipid content. Fishes in the flood season presented higher content of nutrients than drought season. This result also was observed in the minerals profile, where fishes in the flood season presented the highest (p < 0.05) minerals content.
