Abstract Natural mortality, stock–recruitment relationship and sustainable yield of the anchovy ( Engraulis japonicus ) stock in Yellow Sea were estimated based on acoustic assessments wintering from 1987 to 2002. The stock‐recruitment was be: R = 151.1 × SSB e −0.299·SSB , where is given billion fish million tons. optimum at 520 000 tons for period 1987–2002. ecological consequences sharp decline observed after 1996 examined terms reduction biomass production ecosystem, as well such...
Stomach contents of 1603 small yellow croaker Pseudosciaena polyactis , sampled from seasonal bottom trawl surveys in the central Yellow Sea between March 2001 and January 2002, were examined. The results showed that was a carnivorous predator >30 prey species identified stomach analysis. Crustaceans (mainly euphausiids decapods) most important prey, occurring 93·1% stomachs containing food, accounting for 77·6% total food by mass. Feeding activity highest autumn lowest spring winter....
Based on bottom trawl surveys in autumn 2000 and spring 2001, the fish assemblage structure southern Yellow Sea continental shelf of East China was analysed. Four groups fishes were identified for each season by two‐way indicator species analysis (TWIA). Although seasonal migration caused a slight difference assemblages between spring, two major fishes, corresponding to identified. Inshore offshore subsequently separated. Changes water depth may be most important separation waters Sea....
The envelope surface ultrastructure and specific gravity of artificially fertilized eggs the Pacific cod Gadus macrocephalus were examined. unfertilized, demersal slightly adhesive G. almost spherical had no oil globules. Wrinkled with elaborated hexagonal reticulated patterns type I micropyle observed under a scanning electron microscope. adhesiveness was lost at blastodermal‐cap stage after fertilization. micropylar canal sealed by secretion perivitelline fluid, entire became rough....
Seasonal changes in structure or demersal fish assemblages the Yellow Sea are studied by means cluster analysis based on bottom trawl surveys from March 1985 to January I 986. Simple discriminate is used test for significant differences environmental characteristics among sampling station groups which show that species composition and biomass each group season associated with water temperature. The cold mass central plays an important role distribution of One three absolutely dominant...
A survey of free-living nematodes in Dagu River Estuary Qingdao was conducted October 2011, the results were analyzed with help computer systems and digital intelligence tools. And 113 species or taxonomic entities identified, among which dominant Leptolaimus sp.1, Daptonema sp.1 Parodontophora all non-selective deposit feeders. The abundance, biomass production surveyed seas 2998.6 ind·10cm-2, 1199.4 μg dwt·10cm-2 10794.6 dwt·10cm-2·a-1, respectively. average Margalef's richness index (d),...
