To estimate the growth parameters of the banana prawn, P. merguiensis, a tag-recapture study, using vinyl streamer tags (Floy FTSL-731, was undertaken throughout the northern Gulf of Papua. Recapture data were analysed using Fabens' derivation of the von Bertalanffy growth curve. A differential growth rate was found between male and female banana prawns: L∞ and K values for males were 29.34 mm carapace length (C.L.) and 0.136 per week, and for females 35.34 mm C.L. and 0.117 per week, respectively. The assumptions applied in estimating the parameters by the Fabens method were not invalidated. These prawns were shown to have a smaller maximum size than banana prawns from the Gulf of Carpentaria, and it is proposed that two discrete populations exist.

Macrobrachium rosenbergii (De Man, 1879) is a freshwater prawn species that have a high economic value because of its relatively large size compared to the other freshwater prawn species. Exploration to find this species in the Maraja River, Toli-Toli, Central Sulawesi was carried out in January 2019. Sample collected using tray net. Two male specimens of M. rosenbergii were found in the river, with maximum size of carapace length reaching 45.94 mm. Macrobrachium rosenbergii has been found in habitats with clay substrate and slow flowing current. This record extended the distribution of M. rosenbergii, whose spread in Sulawesi has been known only in the southern part of the island, such as in Makassar, Bone, Pinrang, Wajo and Luwu. In this paper, the morphological characters and line drawing of some character M. rosenbergii from the Maraja River were provided.

Novel Approach

We describe the first application of a non-invasive and novel approach to estimate the growth rate of Asconema setubalense (Porifera, Hexactinellida) through the use of 3D photogrammetric methodology. Structure-from-Motion techniques (SfM) were applied to videos acquired with the Politolana ROTV in the El Cachucho Marine Protected Area (MPA) (Cantabrian Sea) on three different dates (2014, 2017, and 2019) over six years. With these data, a multi-temporal study was conducted within the framework of MPA monitoring. A complete 3D reconstruction of the deep-sea floor was achieved with Pix4D Mapper Pro software for each date. Having 3D point clouds of the study area enabled a series of measurements that were impossible to obtain in 2D images. In 3D space, the sizes (height, diameter, cup-perimeter, and cup-surface area) of several A. setubalense specimens were measured each year. The annual growth rates recorded ranged from zero (“no growth”) for a large size specimen, to an average of 2.2 cm year–1 in cup-diameter, and 2.5 cm year–1 in height for developing specimens. Von Bertalanffy growth parameters were estimated. Taking into account the size indicators used in this study and based on the von Bertalanffy growth model, this sponge reaches 95% maximum size at 98 years of age. During the MPA monitoring program, a high number of specimens disappeared. This raised suspicions of a phenomenon affecting the survival of this species in the area. This type of image-based methodology does not cause damage or alterations to benthic communities and should be employed in vulnerable ecosystem studies and MPA monitoring.

Growth rates and migration of P. plebejus were investigated by a series of tagging experiments. Growth records of 157 recaptured, streamer-tagged prawns from 2450 releases were analysed for estimates of von Bertalanffy growth parameters by Fabens method. The size-age relationship differed between sexes with males attaining only 75% of the maximum size of female prawns. There was no appreciable size-related mortality of tagged individuals. Recaptured tagged prawns confirmed the previously determined northerly movement and showed little movement toward deeper water off New South Wales. Once past the easternmost point of the continent dispersal into a range of depths occurred. There was no apparent relationship between rates of movement and size, suggesting that fluctuations in the intensity of the East Australian Current were responsible for variations in these rates. Based on the results of this and other tagging studies, a two-substock hypothesis, defined by the origins of the bulk of recruits, is postulated.

The waters of South Sorong have potential shrimp resources, including abundant banana shrimp (Penaeus merguiensis de Man, 1888). This study aims to obtain information about the morphometric characteristics and growth of banana shrimp in the fishing area around the waters of Kampung Bakoi, South Sorong Regency, West Papua Province. Data collections were carried out in June and October 2019 using descriptive methods with direct observation techniques. Based on the results of data analysis, it was found that the total length of shrimp caught in Bakoi Village was in the range of 10 - 26.8 cm and the most were caught measuring 15.2 cm to 16.4 cm. The model of the relationship between length and weight of banana shrimp in Bakoi Village follows the equation Log W= 1,630+2,659 Log (L) or the form of negative allometric growth. Analysis of the relationship between total length (Y) and carapace length (X) (including rostrum) and the relationship between total length and carapace length (Z) (excluding rostrum) obtained the best estimator models, each following the logarithmic equations L = -2,188 + 10,226 Ln(PK) and L = 4,439 + 9,201 Ln(PKt) respectively.

Annual fishing effort for banana prawns, Penaeus merguiensis (de Man), in the Gulf of Papua increased from low levels in 1974 to around the optimum level in 1978 and peaked at 95000 trawl-hours in 1989 before decreasing after the introduction of effort controls in 1988. Maximum sustainable yield of P. merguiensis was estimated at 559 ± s.e. 25 t (of tails) by linear regression of CPUE (U) on effort using the Schaeffer model. Optimum effort was estimated at 84·0 (± s.e. 11·8) 103 trawl-hours, and an equation for the yield (CE) for a given effort (E) was derived as CE = 13·5E – (8·31 10-2)E2. Application of the CLIMPROD program to Gulf of Papua yield and effort and seasonal rainfall inputs resulted in validated modelling of the fishery. CLIMPROD selected a Schaeffer model for the CPUE–effort relationship (U = a + bE). When CLIMPROD incorporated rainfall (V), the model used was = UaV(b+c) + dV(2b)E (linear–exponential–exponential), where rainfall influences abundance and catchability. For 1974–93 overall, effort was by far the chief determinant of yield. The model using regionally averaged total rainfall in the fourth quarter and unstandardized effort data explained only an extra 5% of the variation in the following year’s catch over the model using effort alone. Standardization of effort data by 3% probably approximates the real effort applied more accurately than does recorded effort.

AbstractWe here report some data on the biology and population structure of Plesionika narval (Fabricius, 1787) captured along the coast of the island of Ustica in the southern Tyrrhenian Sea. Specimens were collected monthly from January to October 2000 using commercial traps at depths ranging from 15 to 100 metres. The carapace length (CL) of females ranged between 7.0 and 26.0 mm, and between 7.0 and 17.0 mm for males. Three modes were identified in the cumulative frequency distribution for females but only two for males. In females, the third modal value was observed only at the deeper sample sites. The Von Bertalanffy growth parameters and performance index ϕ were K = 0.65 y–1, CL∞ = 27.4 mm CL and ϕ = 2.62 for females, and K = 0.71 y–1, CL∞ = 17.8 mm CL and ϕ = 2.28 for males. Ovigerous females were found during the entire period of the investigation, indicating that this species spawns all year round. We compared our results with other data recorded in the literature.

To provide the information necessary for optimizing sampling strategies, the effects of tidal, diurnal, lunar and seasonal cycles on the catchability of juvenile and adolescent banana prawns, P. merguiensis, were examined in the Norman River and in the inshore coastal zone of the Gulf of Carpentaria. A major part of the large variability in catches in both environments was attributable to marked tidal periodicity in catchability. In the river, large catches of juvenile P. merguiensis were taken only at or near the time of low water during both the neap and spring tide periods. Smaller prawns (< 12 mm carapace length) tended to be even more restricted to the time of low water than were larger prawns. This phase shift in catchability of larger prawns was particularly evident in the offshore sampling where large catches of adolescent prawns were made only at high water. Both the number and size of prawns caught also varied considerably with water depth. The reasons for the marked differences in catchability throughout a tidal cycle are not clear, but it is obvious that sampling can be restricted in time, thus providing much more consistent data with a minimum of effort.

Age and growth of the deep water mud shrimp Solenocera melantho (De Man, 1907) was estimated using von Bertalanffy growth model employing modal progression analysis, Ford-Walford method for L∞ and K and t0 by Gulland’s method as well as ELEFAN I (FiSAT II software version 1.2.2) method. The growth parameters estimated by the former method were: L∞= 107.9 mm, K = 2.61 y-1, t0 = 0.1344, φ’ = 4.4825 for males and L∞ = 116.4 mm, K = 3.69 y-1, t0 = 0.1346, φ’ = 4.6997 for females and by the latter method were : L∞ = 106.1 mm, K = 2.17 y-1, t0 = -0.05, φ’ = 4.3879 for males and L∞ = 116.8 mm, K = 2.1 y-1, t0 = -0.05, φ’ = 4.4571 for females. The longevity estimated for both males and females of S. melantho was about 36 months. The females were observed to grow faster than the males.
