Puck Bay KEYWORDS Mya arenaria Population dynamics Biochemical composition Inner Puck Bay Justyna Miąc, Małgorzata Groth, Maciej Wołowicz Institute of Oceanography, Gdańsk University, Gdynia Manuscript received April 4, 1997, in final form May 20, 1997. Abstract Morphometric relationships, the growth rate, sex distribution and annual fluctua- tion in dry flesh weight, biochemical composition and energy value of the sublittoral bivalve Mya arenaria (L.) from Inner Puck Bay were studied from May 1994 to April 1995. M. arenaria grows rapidly during the first year of its life, after which the growth rate decreases. The oldest individual was 5 years old and 53 mm long. Judging from the sex distribution and analysis of biochemical composition, the soft-shell clam breeds in June–July. Analysis of the growth rate and the age distribution confirms the theories that specimens of M. arenaria found in low latitudes reach a smaller maximum size and grow more slowly than those living in higher latitudes. The biochemical composition was determined in the 20–30 mm length class. The mean percentages of the main components of dry flesh were: proteins 47.54 ± 6.0 (male), 51.28 ± 7.7 (female); carbohydrates 9.28 ± 3.7 (male), 10.40 ± 4.0 (female); glycogen 5.74 ± 2.8 (male), 6.72 ± 3.5 (female); lipids 8.67 ± 1.8 (male), 8.79 ± 1.3 (female). Analysis of lipid and carbohydrate (glycogen) content in tissues of the soft-shell clam yielded the highest values in the residue (gonads and hepatopancreas). The lipid level is much higher in early spring, before spawning, than in autumn, when gonad development begins. The highest energy values are reported for August (20.82 J mg−1 in both sexes), the lowest for October (14.38 J mg−1 in males and 14.98 J mg−1 in females). 178 J. Miąc, M. Groth, M. Wołowicz Seasonal changes in energy values are mainly connected with the availability of food and reproduction cycle. 1. Introduction Even though the soft-shell clam, Mya arenaria, is a very common species in Inner Puck Bay, its growth and population dynamics have only been occasionally investigated. Information about this species can be found in Mulicki (1957), Żmudziński (1967), Wenne and Wiktor (1982) and Żmudziński (1990). It must be pointed out that none of these investigations concentrated on M. arenaria; their purpose was to provide a brief, general characterisation of the bay’s ecosystem. There is no data on the biochemical composition of this species. The purpose of the present investigation is to examine in detail the growth rate, sex distribution, biochemical composition and energy values of the soft-shell clam population in Inner Puck Bay. 2. Material and methods All the samples were taken at Rzucewo every month from May 1994 till April 1995 (except the winter months) (see Figs. 1 and 2, Tab. 1) from an area of 1 m2.

Type of sediment, salinity and depth at the sampling site Sediment type Organic matter Salinity Depth gravel and sand < 1% av. 7.5 PSU ∼ 1 m Wet weight was recorded for the whole organism (both shell and body) and separately for the shell and for the body. The flesh was dried at 60◦C for 48 h to constant dry weight (d.w.). D.w. was determined both in the whole body and in the separate tissues – siphon, muscles, mantle, gills and residue. The biomass of the samples in each month was calculated according to the equation: biomass = mass of sample (g) / area (m2). In our case the area was equal to 1 m2. Microscopic examination of gonadal tissues enabled each individual to be assigned to one of three categories: male, female or immature (Brousseau, 1987). Age classes were determined by counting annuli (Newcombe, 1936). Morphometric relationships were estimated using the following equa- tions: S = aL + b, (1) b W = aL , (2) where S – height or weight, L – length, a, b – parameters of the equation. 180 J. Miąc, M. Groth, M. Wołowicz The parameters a and b were estimated. The relationship between age and shell length was estimated using the von Bertalanffy equation (Brousseau and Baglivo, 1987). The 20–30 mm length group was used in the determination of the biochemical composition of whole organisms in each month. Moreover, in October 1994 and March 1995 the lipid, carbohydrate and glycogen contents were determined in soft tissues, i.e. siphon, muscles, mantle, gills and the residue (containing gonads and hepatopancreas). Protein content was determined according to Lowry’s method (Lowry et al., 1951). Lipids were extracted from the bivalve bodies with 2:1 chloroform-methanol (Blight and Dyer, 1959) and then determined by the Marsh and Weinstein method (1966). The quantities of carbohydrates and glycogen were determined as described by Dubois et al. (1956). The energy values were calculated on the basis of the biochemical composition using standard conversion factors: 39.57 J mg−1 for lipids, 23.65 J mg−1 for proteins and 17.16 J mg−1 for carbohydrates (Brody, 1945). 3. Results and discussion 3.1. An investigation of the population Fig. 3 shows the number of individuals per m2 and the biomass fluctuations in Inner Puck Bay soft-shell clam population in each month. The average density of M. arenaria there was 129 indiv. m−2, which is higher than the results obtained by Munch-Petersen (1973) – av. 96 or 500 500 -2 -2 15% 450 14% 450 400 400 13% 350 350 11% 11% 10% 300 300 10% 250 250 7% 8% 200 200 15% 15% 12% 12% 150 10% 150 9% 9% 10% 9% 100 100 50 50 biomass [g m ] abundance0 [indiv. m ] 0 May June July Aug.

Further, the biomasses obtained are much higher than those published by Wenne and Wiktor (1982), who found the biomass of M. arenaria in Inner Puck Bay to be 84 g m−2. M. arenaria is a bioecious pelecypod, the sexes of which are distinguish- able only after examination of the gonads. Of 978 individuals examined, 358 were male and 300 female (Tab. 2). It is therefore reasonable to assume equal numbers of the sexes in the population, which is in good agreement with the results obtained by Pfitzenmeyer (1972), Munch-Petersen (1973) and Brousseau (1987). No evidence of hermaphroditism or protandry was forthcoming, which suggests that these are rather rare phenomena in M. arenaria. Coe and Turner (1938) found only 3 hermaphrodites in more than 1000 individuals, Munch-Petersen (1973) found only 1 in 110 individuals examined, and Brousseau (1987) none at all. Table 2.

The estimated parameters of the equation linking length and width, length and height, length and total wet weight, length and body wet weight, and length and body dry weight for each month are shown in Tab. 3. It must be pointed out that the result obtained for the Inner Puck Bay population of M. arenaria differs from the data obtained by other investigators (see Tab. 4). The differences between these parameters are attributable to the effects of substrate, temperature, salinity etc. found at all these sites. Analysis of parameter a in the length-weight relationship suggests that M. arenaria spawns during June–July, which is in good agreement with the analysis of biochemical composition. 182 J. Miąc, M. Groth, M. Wołowicz The age-shell length relationship is shown in Fig. 5. Clearly, M. arenaria from Inner Puck Bay grows rapidly during the first years of life, after which the growth rate decreases. This agrees well with the results obtained by others (Munch-Petersen, 1973; Feder and Paul, 1974; Brousseau, 1979; Brousseau and Baglivo, 1987). An inverse relationship exists between growth rate and age, a feature common to a number of bivalves. Growth rates within a species are commonly found to increase with rising temperature. Accordingly, bivalves occurring in lower latitudes attain a smaller max- imum length than those living in higher latitudes.

  • The Results of Palynological Investigations As the Evidence of Development of the Rzucewo Culture Neolithic Settlement on the Coast of the Puck Lagoon
    Polish Geological Institute Special Papers, 16 (2005): 65–70 Proceedings of the Workshop “Reconstruction of Quaternary palaeoclimate and palaeoenvironments and their abrupt changes” THE RESULTS OF PALYNOLOGICAL INVESTIGATIONS AS THE EVIDENCE OF DEVELOPMENT OF THE RZUCEWO CULTURE NEOLITHIC SETTLEMENT ON THE COAST OF THE PUCK LAGOON Gra¿yna MIOTK-SZPIGANOWICZ1, Danuta KRÓL2 Abstract. Archaeological investigations have been performed for years in the vicinity of the Rzucewo Headland, on the wes- tern shore of the Puck Lagoon. The best known site of the Neolithic Rzucewo Culture is located there. Also palynological in- vestigation was performed earlier in this area. The present article is an attempt at recapitulating the obtained information. Materials for the palynological tests came both from organic sediments, which occur on the shore of the present Lagoon, and directly from archaeological excavations. The obtained results of both the palynological and archaeological tests made it possible to find out that the earliest traces of the economic activity of humans in this area belong to settlement which was earlier than that of the Rzucewo Culture. This Paraneolithic settlement is dated at the end of the Atlantic Period. The area under investigation was covered then by peatlands and lake, which determined that the main economic activity of humans was fishing, and animal husbandry done on a small scale was only an extra activity of the then population. Archaeologically dated at 4400–3700 years BP, the settlement of the Rzucewo Culture developed when the sea transgressed into the area of the present Puck Lagoon. The results of the research shows that in the economic activity of the inhabitants of the settlement both animal husbandry and farming were treated as matters of secondary importance, while fishing and seal hunting were the main activities.

  • Macrozoobenthos of the Sandy Littoral Zone of the Gulf of Gdańsk 449 3
    Macrozoobenthos OCEANOLOGIA, 39 (4), 1997. of the sandy littoral zone pp. 447–460. 1997, by Institute of of the Gulf of Gdańsk Oceanology PAS. KEYWORDS Gulf of Gdańsk Sandy littoral zone Macrozoobenthos Seasonal changes Lech Kotwicki Institute of Ecology, Polish Academy of Sciences, Dziekanów Leśny Manuscript received October 10, 1997, in final form November 14, 1997. Abstract The aim of the study was to determine the distribution, composition and seasonal variability of the macrozoobenthos in the sandy littoral zone of the Gulf of Gdańsk including the inner part of Puck Bay. The results of qualitative and quantitative investigations of the benthic fauna are presented. Material was collected every month from October 1992 to December 1993 at 10 stations from 0.5 to 1 m depth. A total of 23 species and 5 higher macrofaunal taxa were identified. At each station 2 samples were collected with an 80 cm2 Morduchaj–Boltovski pipe-grab. The average abundance and wet weight of particular taxa were calculated. The analyses showed that in the shallow-bottom zone the most diverse and abundant bottom fauna occurred at the stations situated in the inner Puck Bay. The composition was least diverse at the stations located in the estuary of the river Vistula (Świbno, Mikoszewo). Polychaeta and Bivalvia constituted up to 97% of the bottom fauna biomass; Nereis diversicolor and Mya arenaria were the dominant species. 1. Introduction The Gulf of Gdańsk has frequently been the subject of marine biological and hydrological research. Hagmeier (1926, 1930) published the first numerical results concerning the macrobenthos, and these were followed by the papers of Mulicki (1938), Demel and Mańkowski (1951) and Demel and Mulicki (1954).
