The influence of turbidity on juvenile marine fish in the estuaries of Natal, South africa

Fish Diversity and Water Characteristics in the Reju Khal River

“…Consistent with the mentioned studies, results of the CCA model in the present study explained that temperature, salinity, transparency and phytoplankton seem to have strong correlation with the variability of the species assemblages. One previous study has been reported that salinity is one of the most limiting factors in the distribution of fisheries assemblages from the Uruguayan estuaries [64]. They confirmed the interrupted recruitment pattern of the faunal assemblages in the studied habitat.…”

What are the main local drivers determining richness and fishery yields in tropical coastal fish assemblages?

“…Hidden behind precipitation and wind effects may appear the influence of trophic relationships, reproductive cycles (Keddy and Weiher 1999) and may also a stochastic component (Grossman et al 1982). Moreover, this influence may be modulated by specific variables correlated to the rivers input into the coastal areas, including salinity, river flow (Gillson et al 2012, Mitchell et al 1999, turbidity (Castillo-Rivera et al 2002, Cyrus and Blaber 1987, Johnston et al 2007, Whitfield 1999 or pollution (Lekve et al 2002). Nevertheless, evidences provided here indicated for consistent seasonal changes determined by precipitation and wind direction/intensity in the distribution and abundance of species within coastal fish assemblages.…”

“…The waning moon had significantly higher values for its turbidity according to the variance analysis, confirming thus the relationship between the waning phase and higher turbidity for both capture areas (A1 and A2). Corroborating these results, the highest turbidity was also a determining factor in the abundance of ichthyofauna in Australia (Blaber et al, 1995), Kuwait City in the Arabian Peninsula (Abouseedo et al, 1990) and South Africa (Cyrus, Blaber, 1987). Additionally, turbidity can bring ecological advantages for juvenile fish, as it serves as a cover against predators, but also provides food for the ichthyofauna of the surf zone (Cyrus, Blaber, 1987;Abou-Seedo et al, 1990;Menegassi del Favero, Dias, 2013).…”

On the other hand, a high turbidity can cause as much physiological stress to the fish, as to cause a high availability of food in the environment (Gondolo et al, 2011).…”
