“…The fish apartments would affect upwelling and carry nutrients such as natural coral reefs (Yu et al 2015). It could increase the nutrient content in the upper-lower of seawater and sediment that it had a role as fish foraging (Wang et al 2018).…”

Abstract. Isroni W, Samara SH, Santanumurti MB. 2019. Short Communication: Application of artificial reefs for fisheries enhancement in Probolinggo, Indonesia. Biodiversitas 20: 2273-2278. Overfishing is one of the biggest challenges in the fisheries sector in Probolinggo, Indonesia. The fish apartment (artificial reefs) was one of the solutions to increase the fish resource since it serves as the habitat for fish to live, spawn, and search for food. In this study, the fish apartment was installed in Probolinggo (Karang Katon and Dringu Beach) from 2017 to 2018. This study showed that five fish species (Caesio cuning, Acanthurus achilles, Acanthurus albipectoralis, Sphyraena jello, and Apagon novemfasciatus) were found in Karang Katon while four species (Chaetodon octofasciatus, Chromobotia macracanthus, Nemipterus japonicas, and Lates calcarifer) lived in Dringu Beach. From a total of 333 fishes, A. achilles was the species with the highest composition level of 51.65% (172) in Karang Katon station. In Dringu Beach station, C. octofasciatus had the highest fish species composition level of 46% (183) from a total of 402 fishes. The diversity index and dominance index in Karang Katon station were low at-1.280 and 0.343, respectively. The diversity index and dominance index in Dringu Beach station were also low at -1.115 and 0.3503. A. achilles had the highest density of 34.4 ind/m3 in Karang Katon station while C. octofasciatus had the highest species density of 36.6 ind/m3 in Dringu Beach Station. From this study, it could be concluded that artificial reefs application enhanced the fisheries in Probolinggo, Indonesia, and help its sustainability.

1. Artificial reefs are used around the world for many purposes, including widespread deployment to increase fishery yields. These reefs are well-studied from a direct fisheries-based perspective, drawing largely on traditional theory and methodological approaches from population and community ecology. 2. Here we provide an alternative perspective using basic tenets of ecosystem ecology. We focus largely on primary production, as this ecosystem process necessarily constrains the secondary production of fish and invertebrates. 3. We use this ecosystem ecology viewpoint to examine the long-standing attraction/ production question-do artificial reefs support 'new' fish production or simply attract individuals from other habitats? Central to this discussion is identifying ecological thresholds and self-reinforcing feedbacks. For example, biological or physical processes may facilitate reaching nutrient supply thresholds where fundamental ecological dynamics are shifted, such as enhanced seagrass allocation of resources to above-ground plant structures following aggregation of fish around reefs. 4. Synthesis and applications. We propose that the scope for enhanced primary productivity (or other accelerated ecosystem processes) is an under-utilized guideline that can be used to prioritize artificial reef deployment as part of broader coastal management programmes. Such an ecosystem ecology perspective may provide new insights into the ecological role of artificial reefs and guide the optimization of their deployment and management.

“…Transformation from high-nutrient fish species to low-nutrient fish species reflects the increasing utilization intensity of fishery resources in coral reef waters. Chlorophyll a concentrations (Chl-a), biomass and species quantity of nekton are increased in artificial fish reef waters, which protect and facilitate local marine ecosystem [5] [6] [7]. In marine ecological environment, temperature can affect metabolism, ingestion, spawning and distribution of marine organism directly [8] [9] [10].…”

Dapeng Bay is a typical offshore fisheries area in the South China Sea (SCS). In order to understand the fishery resources, seasonal variations of species composition, dominant species composition, standardized catch per unit effort (SCPUE) and community diversity of fishery resources in Dapeng Bay, China were analyzed based on trawl survey data in spring (March) and summer (May) of 2013 as well as autumn (August) and winter (December) of 2012. Results demonstrated that there are 113 fishery species, which belong to 78 categories, 50 families, 14 catalogues, 3 classes. There are the most species in summer (61 species) and about 56 species in other seasons. In all four seasons, fish and crustacea are dominant species, and there are the fewest cephalopoda. High values of SCPUE occur in spring and autumn, reaching 5.65 and 5.33, respectively. SCPUE is generally low in summer, ranging between 0.52 -0.96. Fish biodiversity is the highest in summer and the lowest in winter.Among biodiversity, Shannon-Wiener diversity index, Margalef diversity index and Pielou evenness index vary in the same trend. They are decreasing from summer, spring, autumn to winter successively. Therefore, there are violent seasonal variation of species composition, quantity and structure of fishery resources in Dapeng Bay. The community structure and function are highly stable in summer, but they have poor stability in autumn and winter. This research can provide scientific references for protection and sustainable use of fishery resources in typical offshore fisheries area in the SCS.
