This study aims to analyze the impact of Covid-19 on the operational conditions of production and distribution at the Palabuhanratu Nusantara Fisheries Port (NFP) before and after the Covid-19 pandemic. Data was collected from May 2021 to July 2022 through interviewing 7 port officers and 25 fishermen based on certain criteria and direct observations in the field. The results shows that the amount of fish production and fish catch per fishing gear decreased significantly in the peak of the pandemic. During the peak of the pandemic (2020), fish catch per fishing gear decreased from gillnet, tuna Long line, toddler fishing, tramel net, hand fishing and purse sein. The distribution of fresh fish at the peak of the pandemic has increased, while the distribution of pindang fish and salted fish has decreased. This happens because fish production at the peak of the pandemic (2020) has decreased, therefore fish in ports do not experience over stock so for Pindang and salted fish is reduced. The highest income for payang and fishing rods was Rp. 650,000 before the pandemic and after the pandemic: the lowest income was Rp. 350,000 for net fishermen. Based on the results of interviews, most fishermen stated that the average household expenditure before and after the pandemic did not change much.

The effects of different protein blends (gliricidia/moringa leaf meals, soybean meal and defatted palm weevil larvae) on Nile tilapia (Oreochromis niloticus) fingerlings were studied for a 10-week feeding period. Six diets with 30 percent crude protein content were formulated, the protein sources were included in equal ratios. Diets were designated as fishmeal/soybean (FMS), palm weevil/soybean (PWS), palm weevil/ moringa (PWM), palm weevil/ gliricidia (PWG), palm weevil/soybean/moringa (PSM) and palm weevil/soybean/gliricidia (PSG). Trials were carried out in triplicates with each having ten (10) fish in a total of 18 tanks. Fish fed diet PSG had the highest mean weight gain of 4.35±0.08 and protein efficiency ratio (PER) of 1.14±0.02. These values were significantly different (P<0.05) from those recorded for fish on other diets. Fish fed diet PSG gave the lowest food conversion ratio (FCR) of 1.10±0.02, with those on diet PWG recording the least. Fish fed diets containing soybean meal (PSM and PSG) gave better performances than those without it. The carcass protein, ash and fat contents differed significantly (P<0.05). This results showed that Oreochromis niloticus fingerlings fed a mix of protein blends could give good performance in terms of growth, nutrient utilization and carcass constituents.

This research aims to evaluate the application of the GMP and SSOP systems and determine the quality of the jambal roti salted fish produced at Mamah Jambal MSMEs, Pangandaran. The research was conducted from September 2021 to January 2022 using the case study method. The research procedure included observation of processing stages, prerequisite program deviation analysis, and microbiological, chemical, and metal contamination testing. The data obtained was compared and analyzed descriptively, referring to Regulation of the Minister of Marine Affairs and Fisheries of the Republic of Indonesia No. 17 of 2019 and SNI 8376:2017. The analysis showed that there were 12 minor deviations, 9 major deviations, and 3 serious deviations in the process of processing jambal roti at Mamah Jambal. Based on the number of deviations applying GMP and SSOP, Mamah Jambal has a C predicate. Quality analysis of jambal roti showed that the samples met microbiological and metal contamination standards in SNI 8376:2017. The test did not find any content of Salmonella sp. and Escherichia coli in the sample. The metal contamination test results revealed the content of cadmium (Cd) to be approximately 0.0037 mg/kg, mercury (Hg) 0.2993 mg/kg, and absence of lead (Pb) content. The results of chemical parameter testing showed a difference in the amount of chemical content in jambal roti salted fish with a predetermined standard, with the water content determined as 55.58%, the salt content determined as 10.6%, and acid insoluble ash content determined as 0.09%.This research aims to evaluate the application of the GMP and SSOP systems and determine the quality of the jambal roti salted fish produced at Mamah Jambal MSMEs, Pangandaran.

Padjadjaran Retention basin is an inland aquatic ecosystem in the form of a water basin that was newly flooded in 2021, located in Cileles Village, Jatinangor District, used as a water storage pond, irrigation source, and fishing. Around the waters there are human activities in the form of fisheries, agriculture, livestock and construction of the Cisumdawu Toll Road which can affect water quality physically and chemically. The purpose of the study was to determine the suitability of the water quality of the Padjadjaran Retention basin for aquaculture with a sustainable floating pond system. Water samples were collected from February to March 2022. The method used in this study is a survey, sampling is carried out using a random sampling method at three stations representing inlets, midlets and water outlets, measurement of water samples is carried out in situ which includes temperature, water transparency, pH, Dissolved oxygen and Carbon dioxide and ex situ measurements include Total suspended solid, Total dissolved solid, Ammonia, Nitrite, Hydrogen sulfide and Biochemical oxygen demand at the Aquatic Resources Laboratory of Padjadjaran University and the Tirtawening Environmental Quality Control Laboratory. The data were analyzed using the Water Quality Suitability Index (WQSI) according to Costa Pierce et al (1990), water quality standards refer to the Indonesian Government Regulation Number 22 of 2021, and Indonesian National Standard number 6494: 2013. The results showed that the water quality of Padjadjaran Retention basin is suitable for use for aquaculture, it is located near the outlet are more suitable for the placement of fish farming containers with a suitability index of 0.53, compared to in the inlet and in the midlet have a suitability index of 0.18 and 0.17, respectively.

The distribution, biology and ontogenic development of the Indian River Shad (Tenualosa ilisha) compared with some other fishes compile in this review. The distribution in the inland waters of Bangladesh, stock/race, movement and migration pattern, size and sex ratio, age of reproduction, maturity and fecundity and ontogenic development of the mouth, digestive tract and accessory gland of T. ilisha discussed in this article. The life cycle of a fish starts after fertilization, but the mouth and digestive tract development start after hatching. Yolk sac larvae (3.83 ± 0.57 mm SL), pre flexion larvae (8.07 ± 1.83 mm SL), flexion larvae (11.50 ± 1.55 mm SL), post flexion larvae (14.72 ± 1.70 mm SL), and juvenile (18.75 ± 3.02 mm SL) were separated into five groups based on morphological characteristics. At the yolk sac stage, the mouth was closed, however at the pre-flexion stage, the larval mouth gape varied between 177 ± 25 and 367 ± 47 µm. The ranges were 241 ± 31 and 497 ± 59 µm, for the flexion stage, 307 ± 38 and 621 ± 74 µm for the post-flexion stage, and 393 ± 61 and 788 ± 119 µm for the early juvenile stage. Development of the digestive tract is complete at the juvenile stage of this species.
