Background The dramatic increase in myotomal muscle mass in post-hatching fish is related to their ability to lastingly produce new muscle fibres, a process termed hyperplasia. The molecular and cellular mechanisms underlying fish muscle hyperplasia largely remain unknown. In this study, we aimed to ...
Freshwater fish populations are rapidly declining globally due to the impacts of rapid climate change and existing non-climatic anthropogenic stressors. In response to these drivers, freshwater fishes are responding by shifting their distribution range, altering the timing of migration and spawning ...
The coral symbiosis is the linchpin of the reef ecosystem, yet the mechanisms that promote and maintain cooperation between hosts and symbionts have not been fully resolved. We used a phylogenetically controlled design to investigate the role of vertical symbiont transmission, an evolutionary mechanism ...
In animal husbandry, livestock industry and research facilities, anaesthetic agents are frequently used to moderate stressful intervention. For mammals and birds, procedures have been established to fine-tune anaesthesia according to the intervention. In ectothermic vertebrates, however, and despite ...
Hatching timing is under strong selection and environmentally cued in many species. Embryos use multiple sensory modalities to inform hatching timing and many have spontaneous hatching patterns adaptively synchronized to natural cycles. Embryos can also adaptively shift their hatching timing in response ...
Bighead carps (Aristichthys nobilis) were divided into four groups with different feeding strategies: group A, nature live food only (fertiliser only, 200 g urea + 160 g ethylamine phosphate + 250 g Huangjintai bio-fertiliser); group B, nature live food + 1/2 formulated feed; group C, nature live food ...
Background. Water quality in the Marilao-Meycauayan-Obando river system (MMORS) of Bulacan, the Philippines, is of great concern due to the pollution load from local industries. The river system is currently used as a source of water for the aquaculture industry in Bulacan. Objectives. In order to ...
Macroalgae are a natural source of clinically relevant molecules such as polyunsaturated and monounsaturated fatty acids. The Antarctic environment, due to its cold climate, leads to high production of these bioactive molecules. Adenocystis utricularis, Curdiea racovitzae, and Georgiella confluens from ...
Parasites are key drivers of phytoplankton bloom dynamics and related aquatic ecosystem processes. Yet, the dearth of morphological and molecular information hinders the assessment of their diversity and ecological role. Using single-cell techniques, we characterise morphologically and molecularly, ...
Fish are ectotherm organisms that move through different thermal zones according to their physiological requirements and environmental availability, a behavior known as thermoregulation. Thermoregulation in ectothermic animals is influenced by their ability to effectively respond to thermal variations. ...
Abstract Arthropods require periodic molting in order to grow which presents a number of challenges to terrestrial taxa. Following ecdysis, the pliant new cuticle is susceptible to buckling under gravity and requires elevated hydrostatic pressure for support. Terrestrial species also require a mechanism ...
Abstract The timing of breeding migration and reproduction links generations and substantially influences individual fitness. In salmonid fishes, such phenological events (seasonal return to freshwater and spawning) vary among populations but are consistent among years, indicating local adaptation ...
Hazardous contaminants, such as nitrite and microcystin-leucine arginine (MC-LR), are released into water bodies during cyanobacterial blooms and may adversely influence the normal physiological function of hydrobiontes. The combined effects of nitrite and MC-LR on the antioxidant defense and innate ...
Positioning, Navigation and Communication on land would be very difficult and nowadays unimaginable without satellite communication networks. The situation underwater is much more complex due to high attenuation of radio waves. Moreover, due to the different nature of communication above and underwater, ...
Emerging Issues in Occupational Safety and Health
In this paper, we define sustainability as the requirement to manage the available resources such that our average quality of life can be shared by future generations. For this definition to make sense, we must define the qualities of life that are important to us—these are the safety of personnel involved ...
The results of implementation of East Nusa Tenggara Marine Affairs and Fisheries Department or Dinas Kelautan dan Perikanan Nusa Tenggara Timur (DKP NTT) web tools and the tests that have been carried out, prove that there has been a decrease in the number of public and industry who registered registration ...
Fishing the major acceptation of the most costal people, but due to the floods and coastal disturbances it is difficult to the fisher man to know about dangers prior going to fishing. In this project it is been planned to implement a fisherman guiding system using ZigBee and GPS Technology. Here in ...
Controlling animal population in natural environment, such as fishery resources, their preys and predators, and some invasive species, is a main part of environmental management. In the real world, both continuous and impulsive interventions are carried out for controlling the population; the latter ...
In this paper, DC electric propulsion system was designed and applied to a small fishing boat to demonstrate the advantages of DC system over AC system. A 10-ton class DC fishing boat was built and tested not only in land-based test site but also in sea trials. In design phase, 30% reduction in the ...
