“…Stock assessment of a fishery is necessary to relieve fishing pressure and ensure the fisheries' sustainability. The fishers and management administrators need to set management actions based on stock assessment information [1][2][3]. However, most of the world's fish stocks are still unassessed because of data limitations, and a shortage of expertise is a significant constraint in fishery management [3,4].…”

“…However, most of the world's fish stocks are still unassessed because of data limitations, and a shortage of expertise is a significant constraint in fishery management [3,4]. In affluent nations, the evaluated fish stock's percentage varies between 10% and 50%, whereas in developing countries, the proportion is often 5% to 20% [1,5]. Due to the high cost of data collection and analysis, resource assessment exists for less than 1% of global fish species.…”

Stock assessment is necessary to understand the status of fishery stocks. However, for the data-poor fishery, it is very challenging to assess the stock status. The length-based Bayesian biomass (LBB) technique is one of the most powerful methods to assess the data-poor fisheries resources that need simple length frequency (LF) data. Addressing the present gap, this study aimed to assess the stock status of three sardines (Sardinella fimbriata, Dussumieria acuta, and D. elopsoides) in the Bay of Bengal (BoB), Bangladesh using the LBB method. The estimated relative biomass for S. fimbriata was B/B0 < BMSY/B0, indicating the overfished biomass, while the assessed B/B0 > BMSY/B0 for D. acuta and D. elopsoides indicates healthy biomass. Additionally, for S. fimbriata, the length at first landing was smaller than the optimum length at first landing (Lc < Lc_opt), indicating an overfishing status, but a safe fishing status was assessed for D. acuta and D. elopsoides (Lc > Lc_opt). Therefore, increasing the mesh size of fishing gears may help to ensure the long-term viability of sardine populations in the BoB, Bangladesh.

“…In general, caution must be exercised when assessing the stock status using this method (Dowling et al, 2019). However, the papers in SMFEA, including those by Liang et al (2020), Ren and Liu (2020), Wang et al (2020a), Zhang et al (2020), and WA2020, have all applied CMSY to assess the stock status, without discussing the potential bias. A discussion related to bias based on previous studies is thus necessary.…”

“…Polacheck et al (1993) reported that the latter performs better. With the advances of mathematics and computer science, the surplus production models had been further developed, such as the CMSY model and the BSM model by Froese et al [22]. These new models can use prior information such as the resilience of the population and the assumption of initial and final relative biomass to calculate the posterior distribution of fishery biological reference points.…”

Fishery resources play an important role in the national economy and ecological diversity in China; it is of great significance to evaluate and rationally exploit the fishery resources. Most fisheries off the coast of China are data-limited, as the complex assessment models are not suitable for its resource assessment. Therefore, data-limited models for fishery resources assessment in China are among the current research hotspots. In this paper, two new data-limited assessment models (Bayesian state–space implementation of the Schaefer production model (BSM) and Monte Carlo MSY estimation model (CMSY)) were used to evaluate the fishery resources of Scomber japonicus and Muraenesox cinereus in the East China Sea. The results showed that the estimated value of MSY of S. japonicus was 220 × 103 t to 240 × 103 t, the estimated value of F/FMSY was greater than one, and the estimated value of B/BMSY was very close to one, indicating that the fishery in the East China Sea had been overfished. The estimated value of MSY for the M. cinereus fishery in the East China Sea ranged from 140 × 103 t to 170 × 103 t. The estimated value of F/FMSY at the biological reference point was greater than one and the estimated value of B/BMSY was less than one, indicating that the fishery had been overfished and resources had declined. Both models can be used for data-limited fisheries offshore of China. To better understand the impact of uncertainty on fishery resource assessment, more research should be carried out on these two data-limited assessment models.
