Stable isotopic studies have shown that it can assimilate plant-derived hard-degradable carbohydrates. Further studies revealed that this species has endogenous enzymes to digest these carbohydrates. We investigated the ability of various organisms to degrade hard-degradable carbohydrates in wetlands from subarctic to subtropical zones and found that they could contribute to their degradation. We found that the enzymes secreted from organisms would bind to the sediment and contribute to the degradation of cellulose. We defined these enzymes as “the environmental enzymes”. Comparison of various sediments revealed that the binding abilities of the sediment for the environmental enzyme were ascribable to oxidized metal, organic matters and the ratio of sand, silt and clay. Regeneration of the wetlands will be important to improve coastal environmental conditions because nearly half of the wetlands have been lost in the last century. Geological diversity as well as biological diversity should be considered to regenerate the wetlands, because the function of environmental enzyme system depends on their contents in the sediments.

Hypoxia Controlled by Hydrodynamics 流体力学控制的缺氧
Pub Date : 2014-10-24 DOI: 10.5047/ABSM.2014.00704.0117

In summer dissolved oxygen is often depleted in the lower and bottom layers in many coastal basins all over the world. This phenomena is called hypoxia. When the oxygen consumption exceeds oxygen supply, the water becomes hypoxic. The oxygen is consumed by decomposing organic matter by bacteria (biochemical processes), while the oxygen is supplied by physical processes such as convection, advection and diffusion. The primary cause of hypoxia is the consumption of oxygen in the water column, but physical processes mainly control its generation, distribution and configuration. In addition to the vertical supply of oxygen by mixing, horizontal transport by estuarine circulation plays the major role in the formation of hypoxia in regions of freshwater influence. As the hypoxic water contains a lot of nutrients, it plays an important role for primary production, producing middle layer chlorophyll maximum in summer and inducing bloom of phytoplankton in autumn. 1. General introduction Oxygen is essential for almost all marine biota, including fishes and invertebrates, to maintain their life. However, the amount of oxygen diluted in the water is limited. The saturation rate of oxygen in the water is only 5.2 mL L–1 (=7.4 mg L–1) under 1 atoms at 20°C. This concentration is significantly lower than that in the air (210 mL L–1). Therefore, marine animals develop advanced gills to take in oxygen efficiently from the seawater. In spite of the advanced organ intrinsic to marine animals, significant decrease of dissolved oxygen (DO) in the water damages them. DO concentration sometimes reduces seriously to the level which has harmful effects on marine animals especially in summer. This water mass is called hypoxia or hypoxic water. The water including nearly zero amount of oxygen is called anoxia. Oxygen depletion exerts a serious impact on marine ecosystems, although the tolerability of marine animals is different among the species. For instance, fishes such as red sea bream and yellowtail are going to die within a few days by exposure to the water with 3 mg L–1 of DO (Ishioka 1982; Yamamoto et al. 1990). In general, oxygen deficiency lower than 4 mg L–1 exerts a baneful influence upon cultured fish (Inoue 1998). On the contrary, benthic animals tend to be tolerant to low oxy118 A.

All rights reserved. the Seto Inland Sea, there are some regions including Osaka Bay, Harima-Nada, Hiuchi-Nada, Hiroshima Bay, Suo-Nada and Beppu Bay, where hypoxia occurs every summer (Fig. 1a). The diversity of species of macro benthic animals is low in the hypoxic regions (Fig. 1b). One of the most wide-spread hypoxia is observed off the coast of Louisiana and Texas, USA (Rabalais et al. 2002). The survey of the region shows an area of about 17,000 km2 experiencing hypoxia, which leads to large changes in bottom water marine life. This region is called the “dead zone” because
夏季,世界上许多沿海盆地的下层和底层溶解氧经常被耗尽。这种现象被称为缺氧。当耗氧量超过供氧量时,水就会缺氧。氧气是通过细菌分解有机物(生化过程)消耗的,而氧气是通过对流、平流和扩散等物理过程提供的。缺氧的主要原因是水体中氧气的消耗,但物理过程主要控制其产生、分布和形态。在受淡水影响的地区,除了垂直混合供氧外,河口环流的水平输送在缺氧形成中起主要作用。由于缺氧水含有大量的营养物质,对初级生产起着重要的作用,夏季产生中层叶绿素最多,秋季诱导浮游植物华。1. 氧气对几乎所有的海洋生物,包括鱼类和无脊椎动物,维持它们的生命都是必不可少的。然而,水中稀释的氧气量是有限的。在20℃下,1个原子下,水中氧的饱和率仅为5.2 mL L-1 (=7.4 mg L-1)。该浓度明显低于空气中的浓度(210 mL L-1)。因此,海洋动物发育出先进的鳃来有效地从海水中吸收氧气。尽管海洋动物的高级器官是固有的,但水中溶解氧(DO)的显著减少会损害它们。DO浓度有时会严重降低到对海洋动物有害的水平,特别是在夏季。这种水团被称为缺氧或低氧水。含氧量几乎为零的水被称为缺氧。缺氧对海洋生态系统产生了严重的影响,但海洋动物对氧气的耐受性因物种而异。例如,红鲷和黄尾鱼等鱼类在接触含有3mg L-1 DO的水后几天内就会死亡(Ishioka 1982;Yamamoto et al. 1990)。一般来说,低于4 mg L-1的缺氧会对养殖鱼产生有害影响(Inoue 1998)。相反,底栖动物倾向于耐受低氧118 A。Kasai / Aqua-BioSci。学报,7:117-145,2014 doi:10.5047/absm.2014.00704.0117©2014 TERRAPUB, Tokyo。版权所有。濑户内海,有大阪湾、Harima-Nada、hiuichi - nada、广岛湾、Suo-Nada和别府湾等地区,每年夏天都会发生缺氧(图1a)。在缺氧地区,大型底栖动物的物种多样性较低(图1b)。最广泛的缺氧之一是在美国路易斯安那州和德克萨斯州海岸观察到的(Rabalais et al. 2002)。对该地区的调查显示,大约17,000平方公里的面积正在经历缺氧,这导致了海底海洋生物的巨大变化。这个地区被称为“死亡区”,因为无法捕获底栖鱼类和底栖动物。缺氧不仅会破坏环境,渔业自然也会受到损害,特别是在封闭的光海湾和湖泊中。夏季在三川湾湾头很少见到底栖鱼类、蟹类和贝类。新司湖和小川原湖是日本最重要的石料蚌咸淡湖,但由于中心深水区夏季缺氧,石料蚌无法生存,因此石料蚌的捕捞被限制在浅于5米的狭窄沿海地区

© 2014 TERRAPUB, Tokyo. All rights reserved. doi:10.5047/absm.2014.00703.0079 Abstract The mummichog is a euryhaline cyprinodont fish native to North America. In this monograph, various reproductive properties, i.e. gonadal changes during ontogeny, gonadal and endocrine changes during annual and daily reproductive cycles, and environmental and endocrine control of reproduction are described. This fish is a spring to summer spawner showing distinct annual changes in gonadal states. A reared strain of this fish shows daily spawning also indicating distinct cycles of oocyte development and maturation. Their annual reproductive cycle is precisely controlled by environmental factors, such as lowering temperature in autumn and winter, warm temperature in spring, and short photoperiod in early autumn. These factors induce the early phase of gonadal development, initiation of the spawning period, and termination of the spawning period, respectively. Their gonadotrophs (FSH cells and LH cells) showed prominent changes during the ontogeny and the annual reproductive cycle. FSH cells appeared at very early stages in the ontogeny, and their abundance showed good correlation to the gonadal stages in the annual cycle. LH cells appeared later, and were abundant only during the spawning period. Plasma FSH levels also showed good correlation to the gonadal stages, whereas plasma LH levels were high only during the spawning period. These findings indicate that FSH is important for gonadal development and LH is responsible for final gametes maturation.

This fish is a spring to summer spawner showing distinct annual changes in gonadal states. A reared strain of this fish shows daily spawning also indicating distinct cycles of oocyte development and maturation.

Utilization of Biological Responses of Fish and Shellfish for Improving Seafood Qualities 利用鱼类和贝类生物反应改善海产品品质

Quality control of seafood has been one major purpose of scientific researches on fish and shellfish. In this monograph, we deal with the utilization of biological responses in the preharvest and postharvest stages of aquatic animals, (1) responses of fish muscle energy metabolisms to environmental temperature changes in postmortem stages, (2) responses of fish and shellfish chromatophore to extrinsic stimuli, and (3) responses of fish to the oral administration of phytosterol related compounds. These approaches will not only confer the improvement of seafood qualities but the addition of extra value to seafood for human consumption. Because animals respond biologically to many factors, comprehensive understanding of biological responses of aquatic animals to environmental factors will lead to the further improvement of seafood qualities.
海产品的质量控制一直是鱼类和贝类科学研究的主要目的之一。在这本专著中,我们讨论了水生动物在收获前和收获后阶段的生物反应的利用,(1)鱼类肌肉能量代谢对死后阶段环境温度变化的反应,(2)鱼类和贝类色素体对外部刺激的反应,(3)鱼类对口服植物甾醇相关化合物的反应。这些方法不仅可以改善海产品的品质,而且可以为人类消费增加海产品的额外价值。由于动物对许多因素有生物学反应,全面了解水生动物对环境因素的生物反应将有助于进一步提高海产品品质。
