Pingguo He's Behavior of Marine Fishes: Capture Processes and PDF

Realizing fish habit with regards to catch approaches in marine fisheries is of basic significance to decreasing bycatch and discards, and to bettering marine fisheries conservation efforts.    a radical knowing of this enables advertisement fishers to extra successfully catch aim species whereas decreasing the trap of undesirable species.

Sample text

If the oxygen consumption rate of the culture animal is known, the loading rate can be computed. The loading rate will depend on dissolved oxygen and un-ionized ammonia criteria, temperature, and size of animals. Guidelines for maximum loadings are presented for holding (Fig. 7A), production (Fig. 7B), and research (Fig. 7C) conditions. For holding conditions, aeration can increase the loading rate. For production conditions, it has been assumed that aeration will be used. The maximum loading for unaerated production conditions is typically 50 to 60% of the aerated values but falls off significantly above about 25~ For research conditions, maximum loading is controlled by the ammonia criteria and aeration will have no effect on loading.

Diagram of tidal datums. , tidal data are collected and tabulated by the National Ocean Survey (NOS). 2). This information is available at a nominal charge. A wide variety of tidal information may be needed in the design process. Depending on the type of intake and pumping cycle, detailed information may be needed on both the high and low tides at the site. The design of the intake, pumping system, and vertical location of the pumps will be strongly influenced by the tidal conditions. Ideally, the detailed information on the distribution of the high and low tides should be used to define the tide in a probabilistic manner.

30 will over-estimate the flows needed to maintain the required un-ionized ammonia concentration. This is due to chemical reactions of metabolic carbon dioxide in 38 water and the impacts of metabolic carbon dioxide on pH and un-ionized ammonia. The mole fraction of ammonia (c~ in Eq. 30) depends strongly on pH. If the metabolic carbon dioxide excreted by the animal reduces the pH, Eq. The impact of these two factors on the required flows depends strongly on the amount of carbon dioxide retained in the water (under normal pHs, negligible ammonia (NH3) is lost to the atmosphere).
