“…This can be seen in Tables 6 and 7 that both the spatial and temporal parameters of salinity consistently exert influence on the abundance of zooplankton. This is according to the research of Almeida et al (2012), Jeyaraj et al (2014), and Takarina et al (2019) which shows the effect of salinity on the distribution and abundance of zooplankton in waters.…”

“…Waya et al (2017) found that transparency significant effect on the abundance of plankton in the lake Lake Victoria, Tanzania. Furthermore, Takarina et al (2019) also found a strong relationship between phytoplankton and the intensity of sunlight and nutrients in the coastal waters of Banten. Thus, both the tides and ebb abundance of phytoplankton are influenced by the presence of sunlight and nutrients.…”

“…In contrast to phytoplankton that requires sunlight and nutrients for growth, zooplankton requires phytoplankton as a food source and salinity conditions where the waters of the wave lake have fluctuations in salinity both spatially and temporally. The results of Almeida et al (2012) shows that salinity impacts the horizontal distribution of zooplankton in an estuarine lagoon in Northeast Brazil, including in the Northern Kerala estuary, India (Jeyaraj et al 2014) and the waters of the Bonang estuary, Demak (Yudhatama et al 2019) and waters Banten Pandeglang beach (Takarina et al 2019). Related to phytoplankton as a food source of zooplankton, Mialet et al (2011) obtained the results of a study that showed that the abundance of zooplankton in water was greatly affected by the abundance of phytoplankton in the fair.…”

“…Various plankton studies have been carried out in lake waters, both natural and artificial lakes, such as Lake Pondok Lapan (Muhtadi et al 2015), Lake Toba (Rahman et al 2016), Lake Ebony (Pratiwi et al 2018a), Lake Matano (Sulawesty 2019), Lake Maninjau (Sulastri et al 2019). Some research on estuarine and mangrove waters has been widely carried out and reported, such as the Mahakam Delta, East Kalimantan (Effendi et al 2016), Belawan Estuary (Dimenta et al 2018), Segara Anakan, Central Java (Dewi et al 2019;Wiyarsih et al 2019); including bay and coastal waters, such as in Gorontalo Bay (Kadim et al 2018), Sunda Strait (Takarina et al 2019), Banten Bay, Lampung and Jakarta (Sidabutar et al 2016;Damar et al 2020). However, no research has been reported on the dynamics of plankton in tidal lakes in Indonesia.…”

Abstract. Muhtadi A, Pulungan A, Nurmaiyah, Fadlhin A, Melati P, Sinaga RZ, Uliya R, Rizki M, Rohim N, Ifanda D, Leidonald R, Wahyuningsih H, Hasani Q. 2020. The dynamics of the plankton community on Lake Siombak, a tropical tidal lake in North Sumatra, Indonesia. Biodiversitas 21: 3707-3719. The tidal lake is a very dynamic estuary ecosystem and very vulnerable to environmental stresses and disturbances. Plankton is an aquatic organism that is very easily affected by environmental pressures and disturbances. This study aimed to reveal the phenomenon of plankton dynamics in tropical tidal lakes in Indonesia. The study was conducted at Siombak Lake from September 2018 to August 2019. Data were collected at high and low tides every month during the full month. The data analysis included plankton abundance, diversity index, and the relationship between water quality and plankton with PCA and succession analysis. The results showed that in Siombak Lake was found 66 genera which consisted of 54 phytoplankton genera and 12 zooplankton genera. Plankton abundance is higher in parts of the lake (stations 1-8) than in the river (stations 9-11) at both high and low tide. Temporally it shows that plankton abundance is higher in the rainy season (Feb-Aug, outside May) than in the rainy season (Sep-Jan, and May). Spatially, plankton in Siombak Lake at high tide is more influenced by TSS, phosphate, and salinity, while at low tide, it is influenced by TSS, Water transparency, BOD, silicate, salinity, and dissolved oxygen. Temporally, plankton in Siombak Lake at high tide is more influenced by salinity, conductivity, Debit, TSS, and salinity, while at low tide, it is influenced by salinity, conductivity, turbidity, TSS, TDS, DO, BOD, and COD. Based on the plankton Frontier succession graph, it shows that Siombak Lake is included in stage 1 and stage 2. Stage 1 occurs before the rainy season (August-September) and the peak of the dry season (March-April).

“…The Indonesian Throughflow makes the distribution of oceanographic parameters very dynamic (Gordon 2005). Even with very dynamic fluctuations of SST and SSC in the waters, it results in alternating upwelling and downwelling events (Atmadipoera and Widyastuti 2015;Sari et al 2018;Wijaya et al 2020) and has the potential to cause biological responses in water (Iskandar et al 2017;Takarina et al 2019). The distribution of skipjack tuna in the waters correlates to the thermal front location, not far from the…”

Abstract. Hidayat R, Zainuddin M, Mallawa A, Mustapha MA, Putri ARS. 2021. Mapping spatial-temporal skipjack tuna habitat as a reference for Fish Aggregating Devices (FADs) settings in Makassar Strait, Indonesia. Biodiversitas 22: 3637-3647. Skipjack tuna (Katsuwonus pelamis) has a high economic value in the international market. Catching skipjack tuna using fish aggregating devices (FADs) without knowing its habitat characteristics can damage the ecosystem. This study aimed to determine suitable fishing areas for setting skipjack’s FADs. The data used included that on catch, sea surface temperature (SST), and sea surface chlorophyll-a (SSC) in the Makassar Strait obtained for 2017-2019. The generalized additive model (GAM) and empirical cumulative distribution function (ECDF) analyses were used to investigate the skipjack’s tuna habitat. A pelagic habitat index (PHI), with PHI > 75%, was applied to determine suitable FAD positions. The gravity center of the skipjack tuna habitat for ten months (January-October 2020) was calculated to validate the model’s results. The results showed that the optimum SST range was from 28.78°C to 31.25°C, while the SSC from 0.18 to 0.28 mg m-3. The best skipjack habitats in the southern Makassar Strait are criterion 4 (PHI > 90%) and criterion 3 (PHI = 85-90%), having a relatively high consistency of the average PHI values. These results can help determine the optimal positions for setting FADs to benefit the global management and sustainable development of skipjack tuna fisheries.

Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of fishes in the Usumacinta River Basin, Guatemala, where Pterygoplichthys is now widespread and locally abundant. We analyzed stable isotopes (δ13C, δ15N) in fish tissues and basal resources to assess the potential impact of Pterygoplichthys on the trophic ecology of six co‐occurring native fishes that feed at a similar trophic level (Astyanax aeneus, Dorosoma petenense, Thorichthys pasionis, Oscura heterospila, Poecilia mexicana, and Gambusia sexradiata). The study was conducted during the dry season in the La Pasion (LPR; high invasion) and San Pedro (SPR; low invasion) rivers. We compared isotopic spaces occupied by native fish and Pterygoplichthys, estimated isotopic overlap, and evaluated the trophic displacement of native species. We also evaluated the relationships of environmental factors, including the relative biomass of the invasive catfish, with δ13C and δ15N signatures. Except for P. mexicana, native species had lower isotopic overlap with the catfish in LPR. Native fish isotopic spaces were compressed and shifted toward higher trophic positions in LPR relative to SPR. Benthic food resources were important for Pterygoplichthys in both rivers, and water‐column resources had greater relative importance (RI) for native species in LPR. Native fish δ13C was significantly associated with Pterygoplichthys biomass, conductivity, and water flow velocity; and water depth and sedimentation had a significant association with native fish δ15N. Findings provide evidence that invasive Pterygoplichthys, along with environmental factors, impact the trophic ecology of native fish in the Usumacinta Basin. Additional field research conducted over longer time periods and mesocosm experiments that account for fish assemblage and environmental variation could elucidate Pterygoplichthys impacts via food resource depletion or habitat alteration.
