Sustainable management of the species requires reliable data on the current pressure of traditional fishing in order to find measures to adjust fishing activities to the recruitment capacity of the species. Therefore, from January to December 2020, data on total length, total weight and sex were collected monthly on a total of 3447 specimens of <i>P. schlegelii</i> caught by local fishermen. The size at first maturity (<i>L</i>₅₀) determined with the statistical package sizeMat was estimated at 6.5 and 6.2 cm for males and females, respectively. The asymptotic length obtained with the TropFishR statistical package was 14.8 cm for both sexes. The growth coefficient and growth performance index were 0.87 year⁻¹ and 2.28, respectively, with a normalised adjustment value of 0.21. Estimates of total, natural and fishing mortality were 3.55, 1.53 and 2.02 year⁻¹, respectively. The current exploitation rate was 0.57 and as such remained above the exploitation rate at 50% of its unexploited biomass (<i>E</i>_0,5 = 0.37). Therefore, a reduction in the current exploitation rate is required by at least 35.1% to maintain sufficient biomass. The estimated size at first capture of 5.9 cm is smaller than <i>L</i>₅₀ for both sexes. These parameters clearly reflect a current trend of overexploitation. Monitoring of fishing efforts and sensitisation of fishermen to catch fish measuring at least 9.3 cm (optimal length) are among the management measures recommended to sustain the <i>P. schlegelii</i> fishing in Benin.</p>\u0000 </div>","PeriodicalId":39473,"journal":{"name":"Lakes and Reservoirs: Research and Management","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Punarbhaba-Atrai-Jamuna river system of northwest Bangladesh is agriculturally important, but the watersheds are frequently affected by droughts in summer and river erosion during the monsoon season. The morphological studies on this river systems are very limited, and hence, the aim of this study was to investigate the morphological characteristics of their largest basins and prioritise the studied watersheds based on erosion vulnerability using two approaches. The remote sensing tools were used to delineate and analyse the linear, areal and relief aspects of the morphometric indices of the six largest river basins of Dinajpur district as the conventional methods of determining the morphological characteristics of a basin are expensive and time-consuming. The studied basins included the following regions—Dinajpur Sadar-Birganj (DS-B), Dinajpur Sadar-Khansama (DS-K), Chirirbandar-Khansama (C-K), Nawabganj-Chirirbandar (N-C), Birampur-Parbatipur (B-P) and Hakimpur-Parbatipur (H-P). The results of the bifurcation ratio, length of overland flow, drainage density, drainage texture and constant channel maintenance indicated that the watersheds were well-dissected and had less flood and erosion risk. The values of form factor, elongation ratio, circularity ratio and compactness coefficient dictated an elongated shape of all the basins with a mature geological adjustment. The multi-criteria prioritisation, combining morphometric analysis with land use factors, offers a holistic understanding of watershed vulnerability signifying DS-B and N-C the most vulnerable watersheds, which require a sustainable development decision making framework for their management.

Because of substantial overfishing and pollution in the fish's natural environment, the wild population of these fishes is drastically dropping, which is a troubling situation that justifies a high priority for conservation. Fish populations can acquire morphometric variations as a result of prolonged isolation and interbreeding. The goal of this study was to use the truss network approach to delineate the stock structure of <i>S. curvifrons</i> based on morphological attributes. A total of 167 fish specimens were gathered from the three sampling stations of Kashmir waters, viz. Telbal Nallah, Dal Lake and Anchar Lake. A total of 37 truss distance measurements were established by joining 15 morphometric landmark points on the fish body. For the fish species currently targeted, MANCOVA demonstrated significant (<i>p</i> &lt; 0.001) morphological heterogeneity among sampling locations. Univariate ANOVA test showed statistically significant differences in 21 out of the total 37 studied morphometric variables among the three sampling sites for <i>S. curvifrons.</i> Based on principal component analysis, the first component (PC1) explained the maximum amount of variation in samples, which is 26.9%. The second component (PC2) contributes 16.5%, and the third (PC3) 10.3% of the total variance. Wilk's lambda test found substantial (<i>p</i> &lt; 0.001) differences in the morphometric measures of the fish across all sampling sites. The discriminant function analysis identified two morphological indices that explained 58.8% and 42.2% of the differences between the groups. Discriminant function analysis further revealed 84.6% correctly classified individuals into their respective populations. The findings from this investigation can be used to develop stock-specific management and conservation strategies for the long-term protection of <i>S. curvifrons</i> in Kashmir water bodies.</p>\u0000 </div>","PeriodicalId":39473,"journal":{"name":"Lakes and Reservoirs: Research and Management","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fish species <i>Badis assamensis</i> is currently listed in the data deficient (DD) category of IUCN. The species has previously been reported in swampy wetlands in the upper reaches of the Brahmaputra valley in Assam; with no detail description on its biology however. The current work redescribes morphology and presents detail reproductive biology of this species based on fresh collection of 377 individuals from the Basistha. length-weight relationships (LWR) analysed in this species indicated an isometric growth; and condition factor (<i>K</i>) indicated a suitable habitat for this species. <i>Badis assamensis</i> exhibits a non-seasonal breeding behaviour twice a year, as analysed from the Gonado-somatic and ovarian indices. During certain period of the year, local people use unscientific ways of fish collection thereby resulting in a steep decline in fish population. The study is believed to lay an insight into this species' geographical range from a swampy wetland habitat in upper reaches of the Brahmaputra basin; to a semi-torrential hill stream habitat in the lower Brahmaputra sub-basin; thereby providing baseline information on this DD species.

However, easy accessibility to the reservoir along with other human-driven disturbances are pushing the stocks at risk. The sustainable fishery management depends on estimating a stock's total allowable catch (TAC), therefore, a recently developed Monte Carlo method (CMSY) was used for five data-limited stocks (catfish, <i>Sperata aor</i>; snakehead, <i>Channa marulius</i>; carp, <i>Labeo rohita</i>; cichlids, <i>Oreochromis mossambicus</i> and featherback, <i>Notopterus notopterus</i>) to estimate their fishery reference points using their catch, resilience and exploitation record at the first and last catch of the year. A Bayesian state-space implementation of the Schaefer surplus production model (BSM) was also used to compare and justify the output of the CMSY. CMSY estimated the maximum sustainable yield (MSY) to be 378, 110, 74.5, 432 and 99 mt for <i>S. aor</i>, <i>C. marulius</i>, <i>L. rohita</i>, <i>O</i>. <i>mossambicus</i> and <i>N. notopterus</i>, respectively.

We used a mixed effects model to assess the influence of changing precipitation patterns and the chemistry of hydrologic inputs on ANC in seven northern Wisconsin, USA seepage lakes from 1984 to 2018. We observed differential ANC responses across lakes to the concomitant changes in precipitation acidity and post-drought oxidative acidity pulses from adjacent wetland soils. Although all study lakes lie within a 4 km² area, mean lake ANC values ranged from 32.8 ± 25.2 μeq L⁻¹ to 71.9 ± 26.8 μeq L⁻¹ and were inversely related to lake landscape position. Lakes with higher mean ANC also showed lower relative variability over time, suggesting that these lakes were better buffered than those with lower ANC. Mixed effects modelling explained 50% of the ANC variability across all lakes, while model explanatory power ranged from 39% to 71% when ANC was assessed within individual lakes. The range of modelled ANC accuracy highlights the complex nature of biogeochemical regulation in individual seepage lakes, despite their shared geographic setting.

The expansion in farm number and perfarm production puts pressure on the environment and increases susceptibility of the cultured fish to disease, leading to production loss by the investors. This study was conducted in cage aquaculture systems located in three riparian counties in Lake Victoria, Kenya to investigate the combined role of biosecurity and adherence to best management practices (BMPs) by looking at the knowledge, attitude, and practices (KAP) of the cage aquaculture farmers. Additionally, it examined the link between biosecurity, BMPs, and water quality in the context of promoting fish health and preventing fish kills in the cage aquaculture of Nile tilapia in Lake Victoria, Kenya. Gulf and open water locations were included in the study design. A semi-structured questionnaire was used to gather qualitative information on the KAP of fish farmers to biosecurity and BMPs in the cage aquaculture farms. For water quality analysis, quantitative data was utilised. Results showed that the farmers had a positive attitude towards various biosecurity and BMP concepts and a moderate level of knowledge, but the practices on the farm were not in concurrence with both their attitudes and knowledge. Using a customised aquaculture performance index score, which assessed compliance to some BMPs and biosecurity, only 8% of the farms under investigation had a good score, while 24% had an average score and the majority (68%) had a poor score. Additionally, a good aquaculture performance index score was inversely related to ammonia levels. This finding suggests the need to locate cage fish farms in areas with better water circulation.

In this study, the process-based model NICE-BGC was extended to couple with LAKE2K in a stratified water quality model to evaluate the global plastic dynamics in both lotic and lentic waters. The new model could simulate riverine plastic transport in inland waters with and without the presence of global major reservoirs and lakes. The result showed the simulated plastic transport with the presence of reservoirs becomes slightly smaller than that without the presence of reservoirs. In particular, the plastic burial simulated by the model became different with and without the lake model when the density of plastic was higher than that of water. This result showed there are limits to the application of the same partial differential equations as in inorganic carbon for the derivatives either with or without the reservoirs as assumed in a previous study by this author, especially when the plastic density is higher than that of water. The model also simulated plastic sedimentation in the global lakes and reservoirs together, and showed that more plastic deposits in the reservoirs than in the lakes with the exception of the Caspian Sea and most of lentic waters are found to deposit more microplastics than macroplastics as pointed out in a previous study. Finally, the weighted average of plastic budget in the global major rivers with the effect of anthropogenic factors such as construction of artificial dams and global lakes in lentic water was quantified. The simulated result also showed that incorporation of the lake model in NICE-BGC led to improved estimates of plastic dynamics in inland waters, and may aid the development of solutions and measures to reduce plastic input to the ocean.</p>\u0000 </div>","PeriodicalId":39473,"journal":{"name":"Lakes and Reservoirs: Research and Management","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142359846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
