Is scuba sampling a relevant method to study microhabitat in lakes? Examples and comparisons for three European species [PDF]

, 2001
We compared fish microhabitat use patterns in the littoral zone of a lake using a new direct method (i.e. Point Abundance Sampling by Scuba, PASS) and the widely used Point Abundance Sampling by Electrofishing technique (PASE).

Isolated reefs support stable fish communities with high abundances of regionally fished species [PDF]

Ecology and Evolution, 2021
AbstractAnthropogenic impacts at isolated and inaccessible reefs are often minimal, offering rare opportunities to observe fish assemblages in a relatively undisturbed state. The remote Rowley Shoals are regarded as one of the healthiest reef systems in the Indian Ocean with demonstrated resilience to natural disturbance, no permanent human population ...

Distance from a fishing community explains fish abundance in a no-take zone with weak compliance [PDF]

, 2015
There are numerous examples of no-take marine reserves effectively conserving fish stocks within their boundaries. However, no-take reserves can be rendered ineffective and turned into ‘paper parks’ through poor compliance and weak enforcement of reserve

The distribution of estuarine fish larvae: nutritional condition and co-occurrence with predators and prey [PDF]

, 2000
Fish larvae were collected monthly between March and September 1997 in the Mira and Guadiana estuaries (southern Portugal). Hydrological parameters were registered and zooplankton samples were obtained simultaneously. Densities of fish larvae (ind.100 m(-

Recent Region-wide Declines in Caribbean Reef Fish Abundance [PDF]

Current Biology, 2009
Profound ecological changes are occurring on coral reefs throughout the tropics, with marked coral cover losses and concomitant algal increases, particularly in the Caribbean region. Historical declines in the abundance of large Caribbean reef fishes likely reflect centuries of overexploitation.
