The aim of this study was to produce a nutritious food, in short-time period, of final low cost, based in frog matrix. Tadpoles obtained from natural fertilization were reared for 100 days and then transported to industrial processing plants, where two primary products were elaborated: the frog tail fillet (FTF) and the non-edible part (NEP). Two canned preserves were developed from the FTF (frog tail fillet in oil/FTFoil; frog tail fillet in tomato sauce/FTFtomato) and, from the NEP, a flour was produced (tadpole flour/TF). The five products were subjected to physical-chemical analysis. Those elaborated from the tail presented chemical composition values close to the frog meat, while NEP and TF showed values of protein, lipid and ash compatible with by-products and ingredients normally used in the animal feed industry. The two canned preserves were subjected to acceptance test and purchase intent test, with emphasis on the FTFoil, which obtained an acceptance rate of 77% from the evaluators. The method of food production proposed proved to be satisfactory, fully reaching the objectives stated. It also can be used in anti-hunger programs, as well as by human and animal industries, improving the quality of the products developed.

Objetivou-se a produção de um alimento nutritivo, em curto espaço de tempo, de custo final baixo, utilizando a rã como matriz. Girinos obtidos a partir de fertilização natural foram criados durante 100 dias e transportados para plantas processadoras, onde foram elaborados dois produtos: o filé da cauda de rã (FTF) e a parte não comestível (NEP). Duas conservas enlatadas foram desenvolvidas a partir do FTF (filé da cauda de rã em óleo/FTFoil; filé da cauda de rã com molho de tomate/FTFtomato) e da NEP, uma farinha produzida (farinha de girino/TF). Os cinco produtos foram submetidos í análise físico-química. Aqueles elaborados a partir do FTF apresentaram valores de composição química próximos aos da carne de rã, enquanto que NEP e TF apresentaram valores de proteínas, lipídios e cinzas compatíveis com coprodutos normalmente usados na indústria de alimentação animal. As duas conservas enlatadas foram submetidas a testes de aceitação e intenção de compra, destacando-se o FTFoil, que obteve uma taxa de aceitação de 77%. O método de produção de alimentos proposto mostrou-se satisfatório, alcançando plenamente os objetivos estabelecidos. Os produtos propostos podem ser utilizados em programas de combate í fome, bem como pelas indústrias de alimentos, nas mais diversas formas.

An aerial multihead camera consists of a photogrammetric system composed of multiple cameras, which are mounted together in a main structure. By combining the images acquired simultaneously from each camera, a single synthetic image with much larger coverage can be generated. Such systems are usually integrated with a position and orientation system (POS) to perform direct georeferencing (DG) or integrated sensor orientation (ISO). However, to obtain mapping products with high accuracy through a DG procedure, it is essential the implementation of the system geometric calibration. Usually, the aerial multihead camera manufacturers perform the geometric calibration using laboratory methods and only the camera interior orientation parameters (IOPs) and their relative orientation parameters (ROPs) are determined to generate the synthetic image (process known as “platform calibration”). The mounting parameters (lever arms and boresight misalignment angles) relating the synthetic image and GNSS/INS reference systems are usually defined using nominal installation values. The objective of this paper is to present an in-flight calibration methodology for multihead camera systems and its assessment for DG applications. The introduced methodology involves three steps: determination of the cameras' IOPs and their ROPs; synthetic image generation; and refinement of the IOPs of the synthetic image and the mounting parameters determination between the synthetic image and GNSS/INS reference systems using different methods. The results of the experiments shown the viability of the proposed methodology for DG applications involving photogrammetric procedures for large-scale mapping requirements.

Commercial exploration of swimming crab is rapidly increasing worldwide. In 2015, total production of crabs (fisheries plus aquaculture) reached almost 1300 thousand tons. One of the most valuable marketing forms is called “soft-shell crab”. The internet is one of the most important marketing channels for soft-shell crab, with prices starting at US$3.5 a unit, but going up to US$8.00–10.00, depending on the size and presentation form of the product (live, cooled, frozen, or processed). In luxury restaurants, a dish containing one large animal may cost well over US$75.00. Increasingly, this market requires exporting companies to present some kind of quality certification of the product or process (mainly certifications related to food safety). Almost all soft-shell crab production is based on crabs caught in the wild, by either trawling or trapping. Crab populations are suffering from environmental impacts associated with human activity, so much that obtaining the raw material (crabs in pre-molt stage) has become the biggest challenge for companies that market soft-shell swimming crab nowadays. Even recognizing the aquaculture as an alternate form to acquire crabs, it is necessary to understand that technology for commercial crab cultivation is still incipient and restricted to some species of few genera, such as Scylla, Portunus, and Callinectes. The present article reviews and discusses the problems and challenges related to the productive chain of soft-shell swimming crab, and presents an overview of the worldwide market, identifying the main exporting and importing centers, and their respective trading methods.
