This Paper reports a study on the benthic faunal abundance and diversity of tiger shrimp P. monodon culture ponds in Perak, west coast of Malaysia Peninsular. Sampling was carried out at three weeks interval throughout the 116 days culture period. In addition, water temperature, dissolved oxygen, salinity, transparency, pH and organic matter of soil were also measured. Results showed that the m...

The study focused on assessment of metal accumulation in certain aquatic macrophytes and benthic organisms to be used as biomonitors. The macrophytes and benthic organisms collected during April to May (2011) from river Cauvery, one of the main fresh water aquatic systems in the south of India. Microwave digested samples of discrete organs of macrophytes and benthic organisms were analyzed for ...

The seasonal and interannual variability of feeding in 15 species benthic marine suspension feeder was studied over 8 yr at Ryder Bay, Antarctica. Feeding strongly bryozoans, gorgonians, polychaetes, dendrochirote holothurians. winter non-feeding period longest the holothurians shortest bryozoans. Bryozoans started late very low chlorophyll concentrations, often when surface fast-ice still pres...

Lakes and lagoons play an important role worldwide, salinity fluctuations significantly affect their ecosystems. Bay Sivash, the world’s largest hypersaline water body, underwent a sharp change in salinity, induced by closing of North Crimean Canal. To monitor shift ecosystem, study was carried out from 2014 to 2020 at 15 sites lagoon. Since closure canal, average increased 22 g L?1 (2013) 94 (...

Warwick (2014; Mar Ecol Prog Ser 505:295−298) suggests that my claim that the biology of marine metazoan benthos may scale continuously with body mass (Bett 2013; Mar Ecol Prog Ser 487:1−6) is an overstatement. His alternative hypothesis is that there is a ‘step-change’ in allometric relationships between the meioand macrobenthos. I continue to propose that simple null hypotheses for standing s...

Fishers have been complaining about the effects of bottom trawl gear on the marine environment since at least the 14th century. Trawl gear affects the environment in both direct and indirect ways. Direct effects include scraping and ploughing of the substrate, sediment resuspension, destruction of benthos, and dumping of processing waste. Indirect effects include post-fishing mortality and long...
