The contribution of four variables, namely Chlorophyll -a (Chl- a ), Sea Surface Temperature (SST), diffuse attenuation coefficient (Kd_490 or Kd), and Photosynthetically Active Radiation (PAR), in predicting the catches of major pelagic fish species (Indian mackerel, horse mackerel, Bombay duck, oil sardine, and other sardines) was evaluated using Canonical Correlation Analysis (CCA). The outcome of the analysis was compared with those obtained by using the following models and methods: the Generalized Linear Model (GLM), the Generalized Additive Model (GAM), connection weight methods, and the explanatory methods of Artificial Neural Networks (ANNs). Both the sets of results were in agreement. Neither the GAM nor the ANNs method showed any clear advantage over each other, although the GAM performed better than the GLM.

Coverage is a factor to reflect the network service quality of the Underwater Wireless Sensor Network (UWSN). Existing UWSN has problems of void-hole and low coverage, which is reducing UWSN lifetime and ability to monitor deployment areas. To improve network coverage and network lifetime, a coverage optimization method based on virtual force and particle swarm optimization (VF-PSO) is proposed in this article. By action of virtual force, the underwater mobile nodes would move to a better position to improve network coverage in this method. For the VF-PSO algorithm, the virtual force can guide the optimization of particles and accelerate the convergence of particles to the global optimal solution. This algorithm could not only optimize the movement trend of nodes to maximize the coverage ratio but also adjust the node distance threshold to reduce the network coverage redundancy. Simulation presents that compared with other typical algorithms, VF-PSO can improve the network connectivity and coverage of the UWSN area, and effectively avoid the network void-hole problem.

Intensive mechanized fishing has induced marked alterations in coastal marine ecosystems resulting in proliferation of low-value, nuisance species in marine fish catches. Assessment of 75 shrimp trawl catches taken in the near-shore waters off Goa, west coast of India during active fishing periods from 2006 – 2008 revealed that the demersal pufferfish, Lagocephalus spadiceus constituted ≈ 27 % by weight of the trawl catch during January – March, and its catch was inversely related to prey and predator species. Sub-tidal rock reefs and submerged rocky patches in the study area offer suitable substrates for spawning, and the predominance of adults during these months suggesting spawning migration. Comparison of the present data with published literature indicates a significant reduction in puffer predators (catfishes). Excessive removal of high-value predators favours the proliferation of pufferfish and its establishment as a meso-predator, probably triggering a potential trophic cascade. The paper discusses the role of removal of High Trophic Level (HTL) species in the proliferation of a meso-predator and its impact on ecosystem function.

A clupeid group (Hilsa) in the Indian sub-continent is represented by three species viz ., Tenualosa toli , T. ilisha and Hilsa kelee , which has great economic significance for the fishers. Tenualosa toil is observed to have narrow distribution in the Indian sub-continent, along with vulnerability status. The present study describes the morphological and meristic features of T. toli collected from the Narmada estuary, Gujarat, India. A single specimen was collected from the bag net catches (10 mm cod-end mesh size) - from Bhadbhut fishing site in December 2019. The size of specimen with a total length of 298 mm, standard length of 224 mm, and weight of 214 g. The morphometric and meristic characters were assessed and compared with other published literature. The present investigation of T. toli suggested that immediate measures should be adopted to rejuvenate the species in the aquatic habitats.

Marine sediments are good sources of both subsistent and anthropogenic ingredients. Recently, an assessment of phylogenetic analysis at the genotypic and molecular levels has revealed the phylogenetic relationships of the prokaryotes. In our study, samples were collected from the surface of sediments in the İ zmir Bay, located in the eastern Aegean Sea and surrounded by the coastal city of İ zmir. Total genomic DNA was extracted from 0.25 g sediment of each sample and used in real-time qPCR to detect 16S rDNA genes of archaea, bacteria, sulfate-reducing bacteria, Desulfobulbus , and Desulfosarcina - Desulfococcus . Our results showed that the maximum number of all samples was found in bacterial primers (1.24×10 9 DNA copy numbers/g), while the minimum number was observed in Desulfosarcina-Desulfococcus primers (1.17×10 2 DNA copy numbers/g). Consequently, genetic studies should focus on investigating the abundance levels of seasonal and annual microbial groups in future studies. analyzed by real-time PCR were identified as a comparative This study was conducted in shallow and deeply buried sediments, and real-time qPCR was used to quantify various groups of microbial primers. Copy number of 16S rRNA gene for prokaryotes, bacteria, Geobacteraceae and sulfate-reducing prokaryotes (dissimilatory (bi)sulfite reductase gene - dsrA) was also investigated. This study shows that the number of all genes in the sediment decreased with increasing depth. The gene numbers of prokaryotes and bacteria showed similar results with a maximum of 10 8 – 10 10 cm -3 gene copies in shallow sediments. The number of copies of the genes of Geobacteraceae and the sulfate-reducing prokaryotes was 10 6 – 10 8 cm -3 gene copies in the sediments. Unlike the present study, Schippers and Neretin 19 examined sulfate-reducing bacteria and common bacteria according to different genes, besides the abundance of Geobacteraceae and prokaryotes. The results of our study were similar in the number of DNA copies of sulfate-reducing bacteria and common bacteria 19 . q-PCR analysis was performed by Einen et al. 40 to quantify and detect archaea and bacteria existing in the glass shell of seabed basalts of different ages and water depths. Results of this study showed that the total number of cells present in the basalt ranged from 6×10 5 to 4×10 6 cells per gram of basalt glass. The samples were taken from different ages and water depths, however, no significant differences were found in the concentrations or relative abundance of archaea and bacteria.

海洋沉积物是生物成分和人为成分的良好来源。近年来，基因型和分子水平的系统发育分析揭示了原核生物的系统发育关系。在我们的研究中，样本是从位于爱琴海东部、被沿海城市İ兹米尔包围的İ兹米尔湾的沉积物表面收集的。从每个样品0.25 g沉积物中提取总基因组DNA，采用实时荧光定量pcr检测古菌、细菌、硫酸盐还原菌、Desulfobulbus和Desulfosarcina - Desulfococcus的16S rDNA基因。结果表明，所有样品中细菌引物的DNA拷贝数最多(1.24×10 9个/g)，而Desulfosarcina-Desulfococcus引物的DNA拷贝数最少(1.17×10 2个/g)。因此，在未来的研究中，遗传研究应侧重于调查季节性和年度微生物群的丰度水平。本研究分别在浅埋和深埋沉积物中进行，采用real-time qPCR对各组微生物引物进行定量分析。研究了16S rRNA基因在原核生物、细菌、土细菌科和硫酸盐还原原核生物中的拷贝数(dissimilatory (bi)亚硫酸盐还原酶基因- dsrA)。该研究表明，沉积物中所有基因的数量随深度的增加而减少。浅层沉积物中原核生物和细菌的基因拷贝数相似，最多为10个8 ~ 10个10 cm -3基因拷贝。土杆菌科和硫酸盐还原原核生物的基因拷贝数为10个6 ~ 10个8 cm -3基因拷贝。与本研究不同的是，Schippers和Neretin 19除了对地杆菌科和原核生物的丰度进行了检测外，还根据不同的基因检测了硫酸盐还原细菌和普通细菌。我们的研究结果在硫酸盐还原菌和普通细菌的DNA拷贝数上是相似的。Einen et al. 40采用q-PCR分析，定量检测不同年龄、不同水深的海底玄武岩玻璃壳中存在的古细菌和细菌。研究结果表明，每克玄武岩玻璃中存在的细胞总数为6×10 5至4×10 6个细胞。这些样本取自不同的年代和不同的水深，然而，在古细菌和细菌的浓度或相对丰度方面没有发现显著差异。与我们的研究相反，Einen等人使用了古细菌和细菌的共同引物，并且研究是基于玄武岩表面微生物的数量。在书房里
