Otolith morphology is widely used for fish stock identification. The sulcus, a structure on the medial side of the otolith, is an important feature in morphological analysis. This study was conducted to evaluate the feasibility of using sulcus morphology for stock identification and to compare its performance with commonly used otolith morphology analysis. Otoliths were collected and analyzed from three geographical groups (the Huanghe (Yellow) River estuary, HHE;the Jiaozhou Bay, JZB;and the Changjiang (Yangtze) River estuary, CJE) of yellow drum Nibea albiflora. The results show that the analysis of sulcus morphology based on shape indices (SIs), elliptic Fourier coefficients (EFc), and a combination of the two parameters identified stocks at overall classification rates of 51.0%, 72.5%, and 73.2%, respectively. These classification rates are similar to those obtained using otolith morphology analysis (57.0%, 73.8%, and 76.5% by SIs, EFc, and their combination, respectively). The findings suggest that sulcus morphology is comparable to the commonly used otolith morphology for identifying stocks of sciaenids, such as the yellow drum. For both otolith and sulcus morphology, EFc could identify the stocks more efficiently than SIs, while the combination of SIs and EFc was even better.

Under artificial LD cycles （6, 12, 18 L）, the elvers of Japanese eel, Anguilla japonica, showed a 24 h cycle of locomotor activity rhythm being most active at light transitions ： the eels＇ activity rose to a primary peak after lights-off, followed by a quiescent period during which they buried into the shelters or lying motionlessly on sand for most of the time, and then reached a secondary peak before lights-on. Elvers could resynchronize their activity rhythm with a new photo cycle within 4 d. Moreover, their activity level at dark phase significantly increased as the light period was prolonged ： higher activity levels during shorter dark period. However, the elvers did not display clearly the existence of a circadian rhythm under constant light or dark conditions. The timing of daily activity rhythm evidenced in the Japanese eels may occur through the action of the LD cycles with a weak participation of an endogenous circadian system. In all the LD cycles, over 99% of the activity occurred in the dark phase, indicating that the eels were always nocturnally active no matter what time of day it might be. Under 12 L conditions, the eels＇ activity level and the time outside sand were significantly elevated both at light and dark phases as temperature increased from 10 - 15 to 20 - 25 ℃. The activity rhythm pattern （ i. e. , two peaks occurring around light transitions） did not apparently change among temperatures. However, in contrast with the primary activity peaks immediately after lights-off at 20 and 25 ℃, the timing of the primary peaks at 10 and 15 ℃ showed a latency of a few hours following lights-off, indicating the inhibiting effect of low temperature on the eels＇ activity.

T his study compared and evaluated the efficiency of two otolith shape descriptors(i.e., the elliptic Fourier transform(EFT) and discrete wavelet transform(DWT)) and morphometrics for stock discrimination. To accomplish this, sample fish from three stocks of yellow croaker L arimichthys polyactis along the Chinese coast(LDB stock from the Liaodong Bay of the Bohai Sea, JZB stock from the Jiaozhou Bay of the Yellow Sea and CJE stock from the Changjiang River estuary of the East China Sea) were used for otolith morphology analyses. The results showed that morphometrics produced an overall classification success rate of 70.8% in contrast with success rates of 80.0% or 82.0% obtained using EFT or DWT, respectively. This suggests that the two shape descriptors comparably discriminated among the stocks and performed more efficiently than morphometrics. During data adjustment and acquisition, some size variables were excluded from the subsequent discriminant analysis for stock discrimination because they were statistically "inef fective," which could reduce the efficiency of morphometrics and lead to relatively low overall classification success. Both EFT and DWT retain the contour coefficients and thus provide a detailed description of otolith shape, which could improve discriminatory efficiency compared with morphometrics.

The otolith morphology of two croaker species(C ollichthys lucidus and C ollichthys niveatus) from three areas(Liaodong Bay, LD; Huanghe(Yellow) River estuary, HRE; Jiaozhou Bay, JZ) along the northern Chinese coast were investigated for species identifi cation and stock discrimination. The otolith contour shape described by elliptic Fourier coefficients(EFC) were analysed using principal components analysis(PCA) and stepwise canonical discriminant analysis(CDA) to identify species and stocks. The two species were well dif ferentiated, with an overall classifi cation success rate of 97.8%. And variations in the otolith shapes were significant enough to discriminate among the three geographical samples of C. lucidus(67.7%) or C. niveatus(65.2%). Relatively high mis-assignment occurred between the geographically adjacent LD and HRE samples, which implied that individual mixing may exist between the two samples. This study yielded information complementary to that derived from genetic studies and provided information for assessing the stock structure of C. lucidus and C. niveatus in the Bohai Sea and the Yellow Sea.

Sand dabs, an important commercial flatfish in the Bohai Sea, has recently decreased gradually in biomass, resulting from overfishing and marine pollution. Artificial culture and multiplication of sand dabs are essential and practical in China. The present paper examines the food habitof this fish to provide detailed information for its culture and multiplication.

鱼类早期生活阶段对外界环境极为敏感,即使低浓度的污染物暴露也可能对其胚胎发育、仔鱼生长存活造成损害,导致种群数量和质量的降低。研究污染物对鱼类早期生活阶段的毒理效应和机制是揭示污染物对生物种群和水生生态系统潜在风险的有效途径。重金属对鱼类的影响在精、卵发生时即可显现。例如,抑制卵(精)母细胞成熟和精子活力降低,使受精率降低;影响受精卵吸水膨胀过程,改变胚胎发育速率、引起胚胎畸形、影响胚胎心率、改变孵化时间、降低孵化率;影响初孵仔鱼体长、造成仔鱼畸形、影响卵黄囊吸收和胚后仔鱼发育生长、摄食行为等。重金属对鱼类早期发育阶段的毒性效应主要取决于金属种类、暴露浓度和受试鱼种及其发育阶段。此外,外界环境条件等因素也会对重金属的毒性产生显著影响。本研究综合分析国内外关于重金属污染物对鱼类精卵、胚胎、仔鱼等早期发育过程生态毒理效应的研究进展,并结合相关报道阐述了其毒性机制。

科学认识鱼类耳石中微量元素沉积与主要水环境因子的关系是基于耳石微化学方法重新构建鱼类生活史及反演其环境履历的重要前提。本研究以环境与耳石中重要元素Sr为例,研究在不同水温(16℃、19℃和22℃)和不同元素浓度(1×、2×和3×Sr)下Sr在褐牙鲆(Paralichthys olivaceus)仔稚鱼耳石形成生长过程中(孵化后15~93 d)的沉积(Sr∶Ca比)特征。结果显示,在不同水温下,耳石中Sr∶Ca比随水体中Sr浓度的升高呈线性增长,而元素分配系数(DSr)随元素浓度的升高先降低然后趋于稳定。在不同Sr浓度下,耳石中Sr∶Ca比及DSr均随水温升高呈增长趋势,二者在22℃时的值均显著高于在其他水温时的值。耳石中Sr沉积能够表征褐牙鲆仔稚鱼所经历的水环境中Sr浓度和水温的变化,可作为元素指纹应用于褐牙鲆早期生活史的重建和环境履历的反演。

运用污染风险评价标准和方法研究了2010年5月（春）、8月（夏）、10月（秋）和12月（冬）莱州湾表层沉积物中7种重金属污染物的时空分布特征、来源及生态风险。结果表明,表层沉积物中Cr、Zn和Pb含量均呈现春季低于其他季节特征,秋季Hg含量是其他季节的4倍,Cu、As和Pb含量无显著季节差异。表层沉积物中Cr、Cu、Zn、As和Cd最高值出现在莱州湾中部及小清河河口等西部水域,来源呈现受自然作用影响较大的特征;而Hg和Pb最高值出现在龙口和界河河口等东部水域,来源呈现受周边工业污染物的人为排放影响较大的特征。基于地理累积指数、生态效应浓度以及Hakanson潜在生态风险指数的综合评价表明,13%~29%的研究区域的表层沉积物受到轻微程度的Cd、Hg和Pb污染,Cd和Hg高值水域达到中等生态风险程度;Hg和As在65%~68%的研究区域的表层沉积物中达到可能对沉积物底质环境及生物群落产生不利生态影响水平。基于对重金属污染物的评价结果,莱州湾表层沉积物质量较好,局部区域存在Hg、Pb、Cd和As的潜在污染风险。
