Fish larvae counting is a technique applied in aquaculture to determine the efficiency of the induction stage and to know the number of fertilized larvae. For this reason, the research aims to improve the count of larvae under 3 fundamental pillars: precision, error and time. For this, we carried out an experimental investigation under a completely randomized design with two counting systems: traditional and artificial vision; each one with 10 repetitions, with 2000 larvae; Later, we carried out the count by means of artificial vision using a camera that captured images of a fish tank with moving fish. The results show that the proposed method is feasible for counting larvae, with 92.65% accuracy, 7.41% error and an average time of 61 seconds per repetition in relation to the traditional counting system: accuracy 64.44%, error 35.61% and time 2009.3 s. The developed system can be replica...

This study presents an extensive review of published and unpublished occurrence records of fish species in the Loreto department. Located in the northeast of the country, Loreto is the most geographically extensive region in the Peruvian territory. Despite the increase in fish collections in Loreto in recent years, the ichthyofauna of this department needs to be more documented. Based on a database of scientific collections and bibliographic information, an updated checklist of the freshwater fishes from Loreto is presented. The results reveal a rich and diversified ichthyofauna, with 873 species distributed in 331 genera, 50 families and 15 orders. The main groups are Characiformes (42.6%), Siluriformes (34.8%), Gymnotiformes (8.6%) and Cichliformes (7.4%). Part of the ichthyofauna has restricted distribution for Loreto (4.7%).

Edible films were elaborated from gelatin solutions (4% w/v) of mahi-mahi skin (Coryphaena hippurus) with 2,5; 5; 7,5 and 10% v/v of oregano extract (OE) and its physicochemical, antimicrobial, structural and surface properties were determined. The control and with 2.5% OE films showed the lowest moisture and opacity values and the highest viscosity values. All films with OE inhibited the growth of Staphylococcus aureus and Proteus vulgaris. Alone films with 10% OE showed antimicrobial activity against all the strains evaluated. Scanning electron microscopy showed that the incorporation of oregano extract in the film-forming solutions, FFS, was related to an increase in the presence of oil droplets in the films, showing the lipid fraction of OE. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analyzes showed the interaction between gelatin, pla...

This paper describes the methodology used to predict the behavior presented by a displacement boat when it sails in certain sea conditions. It is important that the naval engineer determines this behavior in the design phase of the boat, because this way you can evaluate the adverse performance, such as the rise of the propellant, shipping water on deck, slamming and excessive accelerations vertical. The harmful effects described above are predicted by the response spectra of the vessel for a given sea condition and for a given movement. The procedure used for obtaining Response Spectra consists of overlapping Unitary Operator Response in regular waves for a given vessel movement (RAO) and the energy spectrum of Pierson-Moskowitz, used to represent the sea in a certain condition. The operator of the boat united response was determined using a Dynamic Vessel program based on the Th...

An important group of the Ecuadorian population is linked to the artisanal fisheries where most of the fresh fish consumed in the country originates. In the canton Manta, there are approximately 5,000 registered boats known as fibers, which are essential for fishing; however, in the last four years artisanal fishermen have endured massive economic losses by theft of fishing gear and engines at sea, a situation that sometimes it’s even mortal for the crew. The research is based on the situational analysis of artisanal fisheries and the existing problems in the management of its activities, proposing the implementation of a management model to decrease piracy on the high seas and solve other problems related to it. The main Objective of this work is to propose a model to improve the management of artisanal fisheries in Canton Manta.
