    Abstract:

    The stock enhancement program in Laoshan Bay is vital for the Yellow Sea fisheries, and it is essential tounderstand the ecology of the release areas. The springtime species composition and diversity of the Laoshan Bay fishassemblage were determined using bottom trawl surveys conducted in May 2014. The catch included a total of 32 fishspecies in 8 orders, 21 families, and 30 genera. Perciformes were the most abundant, where Gobiidae and Sciaenidaeaccounted for 36.87% and 36.87% of total catch biomass, respectively. The index of relative importance indicated 3dominant fish speciesChaeturichthys stigmatiasHexagrammos otakii, were the next six main species and accounted for 31.98% of total catch biomass. Diversitycalculated as the Margalef species richness index, Shannon-Wiener diversity index, and Pielou evenness index were3.19, 2.34, and 0.68, respectively, which were similar to those of Laizhou Bay, Jiaozhou Bay, and Haizhou Bay, althoughspecies numbers were smaller. Thus, the nine most abundant species accounted for 83.52% of total catch biomassand were also considered important for trophic relationships in the Laoshan Bay springtime fish assemblage.Stomach content analysis indicated three feeding types in the primary species, where was a zooplankivore, and the other six species were benthivores.Benthivorous fish were most abundant, accounting for 57.38% of total catch biomass. The average trophic level of thefish assemblage was 3.52, and the main food species were
