“…Yet, in spite of the availability of structure, we see vast differences in grouper biomass between sites of differing structural stabilities, especially between deeper locations. In the absence of any temporal data on abundance across the entire archipelago, it is difficult to ascertain whether patterns in biomass represent the response of long-lived fish communities to multiple mass-bleaching disturbances or if they merely reflect a natural distribution with respect to depth and exposure (Sabetian 2003). In our survey, depth does emerge as an important factor by itself, positively affecting grouper biomass and structural complexity.…”

“…Exposure and depth work together in mitigating temperature-mediated bleaching responses in corals and in facilitating reef recovery processes (West and Salm 2003). These physical factors, in addition to reef structural complexity and benthic composition, are known to synergistically affect the distribution of reef-associated fish communities (Gust 2002;Sabetian 2003;Floeter et al 2007). The long-term interaction between habitat characteristics, physical disturbances that disrupt habitats, and species life-history characters, 'filters' unfavourable species from habitats of characteristic disturbance regimes (Southwood 1977).…”

Long-lived groupers require structurally stable reefs in the face of repeated climate change disturbances

et al. 2014

Benthic recovery from climate-related disturbances does not always warrant a commensurate functional recovery for reef-associated fish communities. Here, we examine the distribution of benthic groupers (family Serranidae) in coral reef communities from the Lakshadweep archipelago (Arabian Sea) in response to structural complexity and long-term habitat stability. These coral reefs that have been subject to two major El Nin ˜o Southern Oscillation-related coral bleaching events in the last decades (1998 and 2010). First, we employ a long-term (12-yr) benthicmonitoring dataset to track habitat structural stability at twelve reef sites in the archipelago. Structural stability of reefs was strongly driven by exposure to monsoon storms and depth, which made deeper and more sheltered reefs on the eastern aspect more stable than the more exposed (western) and shallower reefs. We surveyed groupers (species richness, abundance, biomass) in 60 sites across the entire archipelago, representing both exposures and depths. Sites were selected along a gradient of structural complexity from very low to high. Grouper biomass appeared to vary with habitat stability with significant differences between depth and exposure; sheltered deep reefs had a higher grouper biomass than either sheltered shallow or exposed (deep and shallow) reefs. Species richness and abundance showed similar (though not significant) trends. More interestingly, average grouper biomass increased exponentially with structural complexity, but only at the sheltered deep (high stability) sites, despite the availability of recovered structure at exposed deep and shallow sites (lower-stability sites). This trend was especially pronounced for long-lived groupers (life span [10 yrs). These results suggest that long-lived groupers may prefer temporally stable reefs, independent of the local availability of habitat structure. In reefs subject to repeated disturbances, the presence of structurally stable reefs may be critical as refuges for functionally important, long-lived species like groupers.

“…Groupers belongs to the subfamily Epinephelinae under the family Epinephelidae, which mainly inhabits tropical and subtropical coral reefs or continental shelves, acting as the top predators maintaining the ecological balance of coral reef ecosystems 1 . Groupers encompasses over 16 genera and more than 160 species, out of which approximately 47 species were currently cultivated for aquaculture 2 , making them globally significant economic fish species.…”

Epinephelus awoara, as known as yellow grouper, is a significant economic marine fish that has been bred artificially in China. However, the genetic structure and evolutionary history of yellow grouper remains largely unknown. Here, this work presents the high-quality chromosome-level genome assembly of yellow grouper using PacBio single molecule sequencing technique (SMRT) and High-through chromosome conformation capture (Hi-C) technologies. The 984.48 Mb chromosome-level genome of yellow grouper was assembled, with a contig N50 length of 39.77 Mb and scaffold N50 length of 41.39 Mb. Approximately 99.76% of assembled sequences were anchored into 24 pseudo-chromosomes with the assistance of Hi-C reads. Furthermore, approximately 41.17% of the genome was composed of repetitive elements. In total, 24,541 protein-coding genes were predicted, of which 22,509 (91.72%) genes were functionally annotated. The highly accurate, chromosome-level reference genome assembly and annotation are crucial to the understanding of population genetic structure, adaptive evolution and speciation of the yellow grouper.

Strengthening the resilience of small-scale fisheries: A modeling approach to explore the use of inshore pelagic resources in Melanesia The International Center for Tropical Agriculture (CIAT) believes that open access contributes to its mission of reducing hunger and poverty, and improving human nutrition in the tropics through research aimed at increasing the eco-efficiency of agriculture. CIAT is committed to creating and sharing knowledge and information openly and globally. We do this through collaborative research as well as through the open sharing of our data, tools, and publications.
