“…CL is a rather homogenous basin, being triangular shaped with strong exposure to wind and wave action (Gasiunaite et al 2008). In contrast, VL is an elongated basin with a clearly marked salinity gradient-from almost freshwater part of the western part of the lagoon fed by rivers to the more saline eastern part being under the influence of the sea, that strongly affects phytoplankton composition (Kruk et al 2016). Therefore, it is not the food selectivity of the larvae, but differences in the food base within the lagoons that seem to determine the composition of the food ingested by the larvae.…”

Four major categories of food items were determined in the gut content of chironomid larvae collected in the Curonian and Vistula Lagoons in the spring-summer period of 2009-2011. These were detritus (range from 88 to 92% of the gut content, by volume), matter of plant (2-7%) and animal origin (0.2-0.5%), and mineral particles (3-7%). Plant matter comprised pine pollen, conidia of fungi, cyanobacteria, green algae and diatoms. Matter of animal origin consisted of remnants of oligochaetes and rotifers. Food content was more diverse in the larvae inhabiting the Curonian Lagoon. The size of mineral particles in gut contents was significantly higher in C. balatonicus, although the distance between the bases of the maxillas, as a predictor of the size of the particles being eaten, was larger in C. plumosus. The gut content analysis suggested lack of clear food selectivity which potentially may lead to interspecific competition for food. However, the strength of interaction can be substantially weakened by several factors: (1) exceptionally favourable food conditions for benthic chironomids in both highly eutrophic lagoons, (2) the ability to occupy areas differing in salinity, (3) different feeding behaviour and (4) the ability to swallow particles of different size spectra.

“…and Sari et al (2016) emphasis that the degradation of mangrove ecosystem also was caused by the decreasing of total economic value from mangrove ecosystem. The degradation of mangrove ecosystem decrease supporting of spawning, feeding and nursery ground for phytoplankton and zooplankton (Cadier et al, 2016;Kruk et al, 2016;Masuda et al, 2017), loosing of the phytoplankton and zooplankton habitat's.…”

The abundance of phytoplankton and zooplankton have correlation with mangrove conditions in coastal area. The mangrove degradation give negative impact for abundance and diversity phytoplankton and zooplankton. The research aimed to analysis and construct prediction model of abundance and biodiversity of phytoplankton and zooplankton in mangrove ecosystem. The research used the transect method (to determine mangrove density), filtering method (to analyze abundance of phytoplankton and zoopankton) and statistical method (to develop estimation modeling of plankton abundance). The results showed that (1) the mangrove density between 250 trees/Ha - 1250 trees/Ha (2) the phytoplankton abundance were 10.675 Indv/L (in mangrove rarely) - 24.290 indv/ L (in mangrove high density), (3) the zooplankton abundance were 261 Indv/L (in mangrove rarely) - 2.204 indv/L (in mangrove high density) (4) The modelling analysis showed that (1) the phytoplankton abundance (y) = 0.0303 x2 - 22.059 x + 13004 and (2) the zooplankton abundance (y) = 0.0057x2 – 5.39 x + 1458.2, with x = mangrove densityKeywords: phytoplankton and zooplankton, mangrove density, abundance, estuary and lagoon

AbstrakPerairan Yapen Timur di Kepulauan Yapen, Papua merupakan perairan semi terbuka dengan potensi sumber daya alam hayati yang sangat tinggi. Penelitian terkini mengenai parameter kimia dan biologi lebih khusus konsentrasi sat hara serta kelimpahan fitoplankton masih sangat terbatas. Penelitian bertujuan untuk mengkaji tentang konsentrasi zat hara (nitrat dan fosfat), dan keterkaitannya dengan kelimpahan fitoplankton di Perairan Yapen Timur, dilakukan pada 5 Januari -5 Februari 2016. Menggunakan metode eksploratif dan purposive sampling method, menggunakan 15 titik pengambilan sampel. Analisis data menggunakan Spektrofotometer pada panjang gelombang 545 nm untuk nitrat dan 885 nm, sedangkan untuk kelimpahan fitoplankton mengunakan persamaan APHA, distribusi spasial nitrat, fosfat dan kelimpahan fitoplankton menggunakan persamaan kriging-metode dan bantuan Sofware Ermaper 7.0. Konsentrasi nitrat ditemukan berkisar antara 0,2 mg -0,7 mg/l, fosfat berkisar antara 0,2 -0,6 mg/l dan kelimpahan fitoplankton berkisar 49.682 -139.490 ind/l. Analisis koefisien korelasi mengindikasikan hubungan antara nitrat dan fitoplankton sebesar 0,3947, fosfat dan fitoplankton sebesar. 0,0068. Konsentrasi nitrat dan fosfat pada lokasi pengamatan mengindikasikan kualitas perairan tergolong dalam perairan oligotrofik, kelimpahan fitoplankton tergolong tinggi dan tidak terdapat blooming pada spesies tertentu, serta hubungan antara konsentrasi nitrat dan fosfat berkorelasi positip terhadap kelimpahan fitoplankton pada lokasi pengamatan.Kata Kunci: Fitoplankton, Fosfat, Nitrat, Yapen-Timur AbstractThe waters of Yapen Timur in Yapen Islands, Papua are semi-open waters with high potential natural resources. Recent research on chemical and biological parameters more specifically of nutrient concentration and phytoplankton abundance is still very limited. The study aimed to observe the concentration of nutrients (nitrates and phosphates), and their relation with the abundance of phytoplankton in Yapen Timur waters, was conducted on January 5Th to February 5 th , 2016. Using explorative method and purposive sampling method, with 15 sampling points. Data analysis using Spectrophotometer at wavelength 545 nm for nitrate and 885 nm, whereas for phytoplankton abundance use APHA equation. Spatial distribution of nitrate, phosphate and phytoplankton abundance using kriging-method equation and Software Ermaper 7.0. Nitrate concentrations were found to be between 0.2 mg -0.7 mg / l, phosphates ranging from 0.2 to 0.6 mg / l and the abundance of phytoplankton ranged from 49,682 to 139,490 ind / l. The correlation coefficient analysis indicates the relationship between nitrite and phytoplankton of 0,6738, phosphate and phytoplankton of. 0,7356. The concentration of nitrate and phosphate at the observation site indicated that the water quality belongs to the oligotrophic waters, the abundance of phytoplankton is high and there is no blooming in certain species, and the relationship between the nitrate and phosphate concentration is positively correlate...
