The association of processed food consumption with health problems has sparked interest among consumers and the food industry in the production of healthier and more sustainable foods. Processed meats, which are made from the skeletal muscle of edible animal species, have unfavorable characteristics due to the incorporation of ingredients and synthetic additives associated with the occurrence of diseases and allergies. In this context, this review presents the pijuayo as a healthy and sustainable alternative in the formulation of meat and fish products. The nutritional benefits of this Amazonian resource are described, as well as its uses reported in the literature. The pulp, peel, stem, and oil extracts of pijuayo have been used to replace animal fat and to act as extenders and colorants in processed meats. The benefits include the enhance of sensory characteristics and acceptability re...

The fishing industry generates large quantities of by-products, most of which are not used and are therefore discarded. The objective of the present research was the elaboration of a pâté-type sausage from mechanically recovered meat of rainbow trout (Oncorhynchus mykiss). The meat was obtained from trout skelons, which were passed through a grinder and sprayed with a mixture of α-tocopherol (0.02%) and ascorbic acid (0.05%). The formulation of the pate was as follows: mechanically recovered trout meat (74.4%), salt (1.3%), sodium tripolyphosphate (0.8%), starch (2%), soy protein isolate (2.4%), margarine (16.7%), soy lecithin (1.9%), onion powder (0.2%), garlic powder (0.2%) and pepper powder (0.1%). Three formulations were prepared: PCR1 (80% cooked meat and 20% raw meat), PCR2 (90% cooked meat and 10% raw meat) and PCR3 (100% cooked meat). For each formulation, the following were e...

The microplastics (PM) present in five fish species of economic importance in Peru were evaluated: Sciaena deliciosa (Tschudi, 1846) (Sciaenidae) “Lorna drum”, Isacia conceptionis (Cuvier, 1830) (Haemulidae) “Cabinza grunt”, Scartichthys gigas (Steindachner, 1876) (Blenniidae) "Giant blenny", Mugil cephalus (Linnaeus, 1758) (Mugilidae) "flathead grey mullet" and Scomber japonicus (Houttuyn, 1782) (Scombridae) "Chub mackerel". The stomach and gill contents of each fish were digested with 10% KOH, followed by a filtration process to search for PM. The MPs were classified by color and by shape. The contamination by PM found in the digestive tract of S. gigas presented higher values than those found in the other four species. No differences were observed in the amount of MP recorded in the gills between species. A positive correlation was only observed between the body length of I. c...

Due to the importance of diversifying the feed input matrix for aquaculture through low-impact local biomass, the effect of replacing corn flour with Lemnaminor flour in diets for juvenile Piaractus brachypomus was evaluated. Four isoprotein diets were formulated with 0% (T0), 25% (T1), 50% (T2) and 100% (T3) replacement and administered to 240 fish grown at 10 fish m³ for 75 days. Animals were fed 5% of their body weight, twice a day. Weight gain, specific growth rate (SGR), apparent feed conversion (AFC), protein efficiency (PE), hepatosomatic index (HSI) and survival were recorded. The results show that partial replacement (T1–T2) maintained the final biomass (2.45 ± 0.09 kg), TCE (2.60 ± 0.11% d), AAC (1.81 ± 0.06) and EP (2.24 ± 0.05) without differences compared to the control. In contrast, total replacement (T3) reduced biomass by 24%, apparent intake by 20% and increased I...

Water is an important element for almost all biological process and several living organisms like fishes, have their habitat in such a kind of aquatic ecosystems. In the city of Villahermosa, Tabasco Mexico is located the Lagoon of las Ilusiones, which is the habitat of several taxonomic groups like fishes. Unfortunately, the imminent pollution of the water body has been documented and recently evaluated the water well-being by cytological and genetics studies through the use of naïve fish species which are a common. The results of several studies show the terrible conditions of water quality, the effects it manifests on the hematopoietic genetic/cellular components; due to the presence of intracellular damage and various atypical levels of chromosome counts.

Between 2014 and 2015, 19 of 25 Peruvian regional authorities were being investigated for activities related to corruption. At the end of 2018, 10 of the 19 involved were tried with custodial sentences as a result of their illegal actions. But, despite this apparent effectiveness at the judicial level, certain cases with a significant number of reports and a similar background to those convicted escaped the sentences against them.Thus, the question addressed in this paper is: what variables explain the evasion of effective sentences in processes linked to corruption by subnational governments? The investigation focuses on the figure of the regional governor (formerly regional president), the crimes for which is accused and the judicial outcome between 2015 and 2018. For this, a comparative study of Tumbes and Callao cases was made, which share interesting similarities such as the imputed...

The Chinese capital fishing fleets extract resources on a global scale in the oceans of the world in order to supply their growing domestic market for marine products, such as the giant squid Dosydicus gigas. Like the Asian giant, other powers in the field carry out extractive exploitation in international waters adjacent to the jurisdictions of riparian countries such as Peru and in all the seas of the world, fed by generous subsidies. This does not prevent fleets from sometimes engaging in practices such as illegal, unreported, unregulated fishing and the exploitation of workers, within the latent danger of overexploitation of maritime resources, with the damage to biodiversity and the ecosystem that this entails. The process is complemented by insertion into the legal fishing circuit, in this case, in Peru, through mergers and acquisitions of various companies in the field. In the con...

Nematodes are parasites widely distributed in aquatic environments and are among the helminths of greatest relevance to global public health. Among the species that affect fish, some exhibit zoonotic potential, that is, they are capable of infecting humans. In parasitized individuals, infections may manifest in different clinical forms, including larval penetration of the gastric or intestinal mucosa, leading to inflammatory processes and, in some cases, gastrointestinal complications. In this context, the present study aimed to conduct a systematic review on the occurrence and distribution of zoonotic nematodes in fish in Brazil, with emphasis on identifying the species involved and their main hosts. Articles published between 2000 and 2025, written in Portuguese and English, and restricted to the Brazilian territory were included. A total of 63 articles were selected, allowing a compre...

Heavy metal contamination in fish and shellfish is a critical issue that compromises food safety and human health in Ecuador. Metals such as mercury (Hg), lead (Pb), cadmium (Cd), and arsenic (As) accumulate in aquatic ecosystems through bioaccumulation and biomagnification processes, increasing their concentration along the food chain. The study reveals a concerning bioaccumulation of heavy metals in aquatic species, particularly in Thunnus albacares and Anadara similis, with Hg (9.60 mg/kg) and As (16.99 mg/kg) levels exceeding regulatory limits. The PRISMA review ensured the quality of the analyzed studies, highlighting the impact of contamination in oil-producing areas. The biomagnification of mercury and the capacity of bivalve mollusks as bioindicators underscore the need for environmental monitoring. These findings reinforce the importance of strict regulations to mitigate risks t...

The aim of this study was to determine the viability and nutritional characteristics of shrimp head silage and fish waste destined for pig feeding. In the conservation process, molasses and rice powder were used as a substrate and Lactobacullus fermentus, obtained from the digestive tract of the piglet, as a fermenter. Temperature, pH and percentage of acidity data were recorded, as well as organoleptic and nutritional characteristics in the first 30 days of conservation. The treatments were T1 = Shrimp head with molasses and yogurt; T2 = Shrimp head with rice powder and yogurt; T3 = Fish residue with molasses and yogurt; and T4 = Fish residue with rice powder and yogurt. T1 and T3 presented acidity and low pH, as well as low temperature during the first week, stabilizing the process on day 15. The fermentation of T2 and T4 was inadequate (not feasible). Aerobic mesophilic microorganisms...
