Swimming Physiology of Fish: Towards Using Exercise to Farm by Kazufumi Hayashida, Kosuke Fukaya, Arjan P. Palstra, Hiroshi

By Kazufumi Hayashida, Kosuke Fukaya, Arjan P. Palstra, Hiroshi Ueda (auth.), Arjan P. Palstra, Josep V. Planas (eds.)

In mild of mounting fishing pressures, elevated aquaculture creation and a transforming into hindrance for fish health, better wisdom at the swimming body structure of fish and its program to fisheries technology and aquaculture is required. This e-book offers contemporary investigations into one of the most severe examples of swimming migrations in salmons, eels and tunas, integrating wisdom on their functionality within the laboratory with that during their typical surroundings. For the 1st time, the applying of swimming in aquaculture is explored by way of assessing the capability affects and invaluable results. The changed dietary necessities of “athletic” fish are reviewed in addition to the consequences of workout on muscle composition and meat caliber utilizing state of the art options in genomics and proteomics. The final chapters introduce zebrafish as a unique workout version and current the newest applied sciences for learning fish swimming and aquaculture applications.

Data modified after Palstra et al. 2008). b Cost of transport (mg O2 kg-1 km-1) of eels in each trial calculated from the oxygen consumption shown in panel (a) swimming. SE was ± 1–2 mg O2 kg-1 km-1. (Data modified after Palstra et al. 1 m s-1. At each speed the oxygen consumption was measured continuously for 90-min. A group of 40 eels were tested twice with a 2 h interval between tests. After the first trial (test 1) the eels were swum at the same speeds but now with a 12 h interval. This endurance test lasted six days (one day per swim speed).

2009; Tsukamoto 2009). The distinctness of these internal and external morphological changes has led to the development of several ‘silver indices’ that can help to identify the stage an eel has reached in the silvering process (Pankhurst 1982; Durif et al. 2005; Okamura et al. 2007). These indices can be extremely helpful in determining the timing of the silvering process, and comparing the silvering process across different catchments and regions. Second, to enable efficient swimming, the specialised organ that controls buoyancy, the swim bladder, also becomes more vascularised, and its walls become thicker.
