Using TASA fishing vessels on the Peruvian coast during the period 2007 to 2016, the Oxygen Minimum Zone (OMZ) was determined through echograms obtained using a digital echo sounders ES60 and ES70 SIMRAD. The purse-seine fleet operates during two seasons per year for anchovy fishing as well as in fishing ...
The target strength (TS) of a species is a variable used for the biomass estimation, this force is a measurement of the received echo or reflected energy of the species, given by the sound wave transmission generated by the echo sounder. The objective of this work is developing the TS of the Peruvian ...
OceanNet is a Long Range Wi-Fi based system that has been designed to provide internet services for fishermen who venture into the sea for several days together as far as 60 kms and beyond. Internet availability would enable options such as onshore communication (text and calls) using VOIP, localization ...
Lake whitefish (Coregonus clupeaformis) are an ecologically, economically, and culturally important species to the native and non-native fishers of Lake Huron, Canada. Studying the effects of anthropogenic activity on lake whitefish is of utmost importance to ensure this species remains viable in its ...
The Visible Infrared Imaging Radiometer Suite (VIIRS) collects two styles of low light imaging data at night, enabling the detection of electric lighting and combustion sources. NOAA operates two near-real time processing chains to exploit the low light imaging data collected by VIIRS. One is focused ...
Two experiences of target strength measurement of Sprattus fuegensis carried out through two differentiated ex situ methodological approaches “fish group” and “individual mark”. Both experiences were carried out on board of the artisanal vessel Huracán I The system used were (S1) conformed by a 38 Khz ...
Tuna are an important source of food and protein. Among this group of fishes, seven species represent 90% of the global catches and the main species is the skipjack (Katsuwonus pelamis) with a total production of over three million ton. We worked on a Skipjack Fishery Improvement Project in the Brazilian ...
The Peruvian industrial fleet deploys digital acoustic technology, mostly commercial echosounders, which must be calibrated when used for quantitative purposes. However no calibration routine is included in the standard version of the operating software of these echosounders, so that a Protocol has ...
In the Gulf of California, small pelagic fish like sardines, anchovies and mackerels are of ecological and economic importance. A particular feature of these species is their tendency to form schools, which can be described by their size, acoustic density, position and location in the water column. ...
Diacronema vlkianum is a marine microalgae for which supposed health promoting effects have been claimed based on its phytochemical composition. The potential use of its biomass as health ingredient, including detox-shakes, and the lack of bioavailability studies were the main concerns. In order to ...
Data on nutrient contents of freshwater crabs are important for ecological studies and species conservation assessments, especially when the species concerned is threatened among others by habitat destruction and uncontrolled resources utilisation. Indeed comprehensive biological information is required ...
The study of river water quality plays an important role in assessing the pollution status and health of the water bodies. Human-induced activities such as domestic activities, aquaculture, agriculture and industries have detrimentally affected the river water quality. Pinang River is one of the important ...
The importance of polyunsaturated fatty acid (PUFA) in microalgae was widely reported. In this study, six isolated microalgae from Teluk Aling, Penang National Park were screened for PUFA contents. Isochrysis maritima showed the best polyunsaturated fatty acids essential for aquaculture species compared ...
The Ephemeroptera, Plecoptera and Trichoptera (EPT) community structure and the specific sensitivity of certain EPT genera were found to be influenced by water parameters in the rivers of Gunung Jerai Forest Reserve (GJFR) in the north of peninsular Malaysia. The scores of EPT taxa richness of >10 ...
In this paper, we studied some biological aspects of big eye scad (Selar crumenophthalmus) from Maldives. The fish sample was collected from the local fish market at Bangaa Faru, Male, Maldives. The length of the samples were ranged from 7.7 cm to 24.5 cm (mean value = 16.85 ± 2.82 cm) in fork length. ...
The nutritional composition of the dried seaweed Ulva lactuca from Pameungpeuk waters, including proximate, vitamins, minerals, dietary fibre and heavy metal has been carried out. The objective of this present study is to know the nutritional composition of the dried seaweed U. lactuca for utilisation ...
In this study, a Lactic acid bacteria (LAB) strain was isolated on MRS medium from gastro-intestinal tissues of Broadhead catfish (Clarias macrocephalus). Out of 50 isolates, 25 isolates were found to be positive on lactose utilisation test and were identified to be gram positive cocci. Using disc diffusion ...
Aim: The aim of this study is to identify antibiogram and heavy metal resistance pattern of Aeromonas hydrophila and Edwardsiella tarda isolated from red hybrid tilapia (Oreochromis spp.) coinfected with motile aeromonas septicemia and edwardsiellosis in four commercial fish farms. Materials and Methods: A. ...
Aim: The objective of this research is to report parameters for breeding soundness evaluation, semen extension, and cryopreservation in Rusa timorensis. Materials and Methods: Seven healthy stags were chosen for semen collection using an electroejaculator. The collections were performed twice in ...
Background Two trials were performed to evaluate a partially defatted Hermetia illucens (HI) larvae meal as potential feed ingredient in rainbow trout (Oncorhynchus mykiss Walbaum) diets. In the first trial, 360 trout (178.9 ± 9.8 g of mean initial body weight) were randomly divided into three experimental ...
