“…Source: Gasper et al, 2012 [13] Figure 1 illustrates the possible risk associated with the intensive cage or pen mariculture practices widely adopted in India and the world to meet the increased demand for seafood products. In India the species which is mostly cultured in cage farming is Pangasianodon hypophthalmus and Genetically Improved Farmed Tilapia (GIFT) while salmon, yellow tail, etc.…”

Integrated Multi-Trophic Aquaculture (IMTA) represents a sustainable approach to aquaculture that promotes the co-cultivation of multiple species to enhance ecosystem efficiency and productivity. This paper provides a comprehensive review of IMTA practices in India, examining their potential benefits, encountered challenges, and outlining future directions for development. India's diverse aquatic ecosystems offer ample opportunities for IMTA implementation, with various species combinations including finfish, shellfish, and seaweeds being explored. Despite its potential, IMTA faces numerous challenges in India, ranging from regulatory hurdles and technical constraints to socio-economic factors and environmental concerns. The review synthesizes existing research and industry experiences to assess the current status of IMTA in India, highlighting successful case studies and identifying areas for improvement. Additionally, the paper discusses potential strategies for overcoming barriers to IMTA adoption and suggests avenues for future research and policy interventions to promote its widespread implementation. By addressing these issues, India can harness the full potential of IMTA to enhance sustainable aquaculture practices and contribute to food security, economic development, and environmental conservation.

“…Japan mainly explores the green transformation model of mariculture from the two aspects of realizing the integration of production, university, research, and application and improving the monitoring technology and system of mariculture [12,13]. In recent years, Western developed fishing countries have continued to increase investment in fishery clean and energy-saving technologies, providing sufficient financial support for the research and development of related technologies, prompting a series of key technologies to break through, and promoting and applying the low-energy and low-emission mariculture model has become a consensus across all countries [14,15]. Under the wave of global mariculture green development, in 2019, ten ministries and commissions jointly issued a programed document on the green development of aquaculture in China, "Several Opinions on Accelerating the Green Development of Aquaculture", and in 2021, the Ministry of Agriculture and Rural Affairs issued a notice on the implementation of the "Five Major Actions" to promote green and healthy aquaculture technology.…”

It is imperative to achieve the high-quality development of fisheries and green transformation of mariculture. Based on the data of marine aquaculture fisheries in China from 2006 to 2019, this research uses the Super-SBM (Slacks-Based Measure) model to measure the efficiency of marine green aquaculture in China and analyzes the regional gap, evolution trend, and driving factors of marine green aquaculture efficiency in nine coastal provinces in China. The results are as follows: (1) The Super-SBM measurement results showed that the efficiency of marine green aquaculture in China showed a fluctuating upward trend from 2006 to 2019. The results of nuclear density estimation and Dagum Gini coefficient show that there is an obvious regional gap in the efficiency of marine green aquaculture in China, and the regional gap is increasing with time. The Dagum Gini coefficient decomposition results show that inter-regional differences and supervariable density differences were the main sources of marine green aquaculture efficiency. The results of barycentric elliptic standard deviation show that the gravity center of marine green aquaculture efficiency in China shifted to the south from 2006 to 2019, indicating that the efficiency of marine green aquaculture in southern China has had a high degree of improvement. (2) The spatial Markov chain results show that spatial proximity plays a key role in the state transfer of marine green aquaculture efficiency. The higher the efficiency of marine green aquaculture in neighboring provinces, the greater the effect on improving the efficiency of marine green aquaculture in the province. The state transfer of marine green aquaculture efficiency usually occurs between similar horizontal states, and there is less “leapfrog” transfer. (3) The results of the geographic detector show that the number of professional mariculture practitioners is the core driving factor and plays a leading role in the regional gap in the efficiency of marine green aquaculture in China. The explanatory power of the interaction of the two factors on the regional gap of marine green aquaculture efficiency is more than 90%, which is much higher than the explanatory power of a single factor. The regional gap of marine green aquaculture efficiency is the result of multiple driving factors.

“…Newell, 2004), with several bivalve species being targeted by commercial fisheries and recreational harvesting activities (e.g. Gaspar et al ., 2012). In Portugal, small-scale bivalve fisheries are traditional and relevant activities at cultural, social, and economic levels, due to fleet size, number of fishermen, and both volume and value of the catches (Gaspar et al ., 2002 a ; Oliveira et al ., 2013; Rufino et al ., 2017; Almeida et al ., 2021).…”

This study reports the spatial and depth distributions, occurrence and prevalence, infestation rate and intensity of the pea crab Pinnotheres pisum colonising five commercial bivalve species (Chamelea gallina, Donax semistriatus, Donax trunculus, Donax vittatus, and Spisula solida) along the south and southwest coasts of Portugal. In addition, the study also analysed the colonisation pattern, morphometric measurements and relative growth of P. pisum inhabiting those bivalve species. Overall, 33,370 bivalves were analysed, collected in 371 sampling stations at depths ranging from 3 to 25 m. A total of 102 bivalves hosted 106 P. pisum, corresponding to an infestation rate of 0.31%. Besides 13 juveniles, were recorded 60 males and 33 females of P. pisum, corresponding to a male-biased sex ratio (1M: 0.6F). Pea crabs carapace width ranged from 1.3 to 13.5 mm and males were smaller than females (hard females were also smaller than ovigerous soft females). In general, larger and heavier bivalves hosted larger and heavier P. pisum. Pea crabs morphometric relationships presented negative allometries, reflecting slower growth rates in carapace length and total weight compared to carapace width throughout the species ontogeny. Overall, this study provides valuable insights into diverse descriptors of bivalves' colonisation by P. pisum, comparing the main results and trends with analogous information available throughout the species distributional range. Although the current fairly low infestation by P. pisum does not constitute a health concern for these bivalve species, its evolution under a climate change scenario should be periodically monitored in the mid- and long-term.
